Answer:
C. A negative feedback loop.
Explanation:
As we know the melting of Arctic ice caps and polar regions due to global warming impact, and the release of methane a harmful natural gas in the environment from the Arctic system has created a negative impact upon the ecological system impacting badly and hence destroying it. The occurrence of a negative feedback is a way of earth saying that its resource cannot no longer bear the pressure and hence a balance needs to be made within this system, so system analysis predicts show this negative feedback as a disturbance being created.How does a stream typically change as it flows from its headwaters to its mouth?
A. discharge decreases, channel shape widens
B. gradient increases, channel shape narrows
C. gradient decreases, discharge remains the same
D. gradient decreases, discharge increases
Answer:
D. Gradient decreases, discharge increases.
Explanation:
As steam is a body of water that carries rock particles and dissolved ions, discharge is measured in terms of volume/time (m3/sec). So when a river discharges its flow from a headwater to its mouth the velocity increases in the downstream direction. Thus the river load-carrying capacity increases downwards and so does the discharge rate. The discharge rate can also be influenced due to the rainfall patterns, volume of water and velocity of flow. Rock types also impact the streamflow if it is a porous rock, the surface will absorb more of moisture content and comparative more will be the water penetration towers the mouth of the flow.A stream typically changes as it flows from its headwaters to its mouth by widening its channel, slowing down the current, and increasing its temperature. This is due to a decrease in gradient, an increase in volume, and the deposition of sediment.
Explanation:As a river or stream flows from its headwaters to its mouth, there are several changes that typically occur. The width of the channel gradually widens and the current slows down. This is due to a decrease in gradient and an increase in volume as tributaries join the main stream. As a result, more sediment is carried by the slower-moving water, leading to increased deposition. Additionally, the water temperature typically increases as it moves downstream.

Based on principles discussed earlier in the course, you know that the annual temperature range of places located in the interior of a continent is ________ those located along the coast at the same latitude.
A) greater than
B) less than
C) the same as
Answer: A) greater than
Explanation:
Continental climates usually have a greater annual variation in temperature than coastal regions, meaning hot summers followed by cold winters. This happens because winds that blow overland prevail
in inland areas, and the temperatures are not decreased by nearby bodies of water. Coastal areas have a smaller range of temperature than continental land because of the ocean´s heat capacity.

Middle latitude swirls are storm systems that transport humid warm air poleward to be replaced by colder and drier polar air moving equatorward. Storm motions transfer ________ within the earth system.
Answer:
Warm atmospheric water vapour
Explanation:
As the middle latitudes on Earth lie between 23°26 and 66°33" north, and between 23°26' and 66°33" south. These are middle latitudes tropical cyclones or storms that cause swirls that transport humidity and warm air polewards to be replaced by the colder and drier air moving equatorward. Anticyclone winds rotate clockwise in the Northern Hemisphere around a center of high pressure. They may be caused by the polar winds coming down and in return warm wind collision going up i.e a type of air front produced over water. Anti Trades and westerlies are found in this latitude. Their wavelengths may extend to 4000 kilometers and are generally slow-moving from east to west, with earth's rotational speed.What is a reason there are so many different types of maps? Disagreement about what one to use Maps are always outdated Some maps are better looking than others Different maps used for different purposes
Answer:
Yes, different types of maps are made to represent various aspects of earth.
Explanation:
As the earth needs to be studied by use of maps that are a 2 dimensional representation of earth on a globe of 3 dimensions the use of various types of maps is done so as to differentiate each and every phenomenon distinct from other as the need arises as the example of Topographic maps shows relief use to depict relief feature and other types of feature like vegetation etc. The use of large and small scale maps to depict surface features on a sheet of paper in terms of details shown. The use of hydrological maps to depict the natural bodies of water arranged in various layers of the earth's water cycle. The map may become outdated when the geographic features obtained on the earth's surface change or when there is a need to revise the maps in response to the changes in the political boundaries of any country. Some maps drawn at various points of time may be differently projected and thus appear to look different or better , but it's mainly due to the type of projection that the map displays like earlier maps are in the form a heart shape later on the shape and size to represent the earth's surface changed as the availability of data and maps began to be made wider and that changed how they look.List five professions that use geography and explain who these professions use those skills.
Answer:
Five professional are Cartographer, Town planner, Teachers, Gis experts, Demographers,
Explanation:
As cartography is the art and science of making maps the Cartographers use geographic data on maps from various maps, diagrams and define locational boundaries. Use the geographic principles of the globe to form models of the earth's surface. Town planners or urban geographers use the art of geography to interpret and plan the cities formation and development, they also use the basic geographic techniques like zoning and land-use patterns of a city, the internal structure, etc. Teachers, they use their knowledge of geography to teach and develop approaches so as the student can understand the world better, they use innovative ideas and out of text information to spread this body of knowledge far and wide. Demographers, generally study the population parameters based on the statistics and data collected from the surveys both primary and secondary. Population studies also come under this field, and analysis the population age and sex ratio, etc. Gis experts or professional working with the software need to have a thorough knowledge of geography as it helps them to formalise and plan various types of maps the as they are governed by the government bodies and private groups in the country.Earthquakes can be predicted on a short-term basis with considerable accuracy (correct time and place most of the time) by careful measurement of precursor phenomena such as foreshocks and ground deformation.

In which of the four time periods did the Sun-centered model gain widespread acceptance, meaning that nearly everyone who looked at the evidence concluded that it was correct?
a. Ancient Greece (through Ptolemy, ~150 A.D.)
b. Early Copernican Revolution (about 1543 – 1600)
c. Later Copernican Revolution (about 1609-1630)
d. Newton and beyond (after about 1687)
Answer: c. Later Copernican Revolution (about 1609-1630)
Explanation:
During the Middle Ages, it was believed that the Earth remained motionless, occupying the center of a universe subject to uniform circular motion where Earth was the only world. All this because the only accepted idea was that of Ptolemy.
Until the Polish astronomer Nicolaus Copernicus proposed that the Earth annually orbits the Sun and rotates once a day on its own axis. He also dared to affirm that the other planets also orbited the Sun as a fixed point. This meant the Earth was no longer unique, nor did it occupy the center of the known universe.
It was on this main idea that the Copernican revolution was based, by changing the Earth for the Sun as the center of the Universe, bringing with it a paradigm shift from the ptolemaic model of the heavens (the stationary Earth in the center of the universe) to the heliocentric model with the Sun in the center of the solar system.
These ideas were published by Copernicus in De revolutionibus orbium coelestium.
In a study of genetic variation of the Graceland gene, a researcher finds that there are two alleles in a population. In a large sample (500 individuals), the frequency of heterozygotes is 0.63. Is the population in Hardy-Weinberg equilibrium?
Answer:
No, Hardy Weinberg Equilibrium is a theory that states the allele and genotype frequencies in a population will remain constant irrespective of the sexs.
Explanation:
Derivations from the HWE Hardy Weinberg Equilibrium assume that organisms are diploid, population size is infinite, and mating is random. In all the equilibrium the four fundamental factors like the selection, mutation, random mating including interbreeding and small population size. So, if the number of heterozygotes is 34 then the significant level is 0.067. So higher the significance level higher is the heterozygotes. In the absence of selection and genetic drift, all the frequencies within variables are constant. This principle was named by G, H Hardy.All lines of longitude are measured east and west of what imaginary line
Using paragraph 43,explain the contrast between the behavior of the wounded man and unwounded man.
43. The wounded man scrambled hard still for the top of the ridge without devoting any glances to the direction whence the bullets came, and the other man followed at an equal pace; but he was differen, in that he looked back anxiously three times.
Written answer
English
The wounded man is so motivated to escape that he doesn't care to look back. He's already wounded, so his motivation to leave the vicinity of the shooting is understandable.
The other man is evidently concerned about the source of the bullets, for some reason. Maybe to gauge whether the shooter is pursuing?
The wounded man's behavior displays an undistracted determination, likely fueled by a survival instinct, while the unwounded man's frequent anxious glances back portray more awareness or fear of the danger they're in.
Explanation:In paragraph 43, there is a stark contrast drawn between the wounded and unwounded man's behavior. The wounded man is depicted as focused solely on his goal, scrambling hard for the top of the ridge without any regard to where the bullets are coming from. This could signify his desperation, determination, and possibly, his instinct for survival overriding his fear.
On the other hand, the unwounded man, despite being in the same situation and maintaining an equal pace, manifests a different behavior. He frequently looks back anxiously, indicating that he is more aware and perhaps more fearful of the danger behind them. His actions could represent caution, anxiety or a deeper concern with their predicament.

Answer:
Biological Productivity.
Explanation:
As the term ecological footprint means the impact of one's foot over the ecological systems. Its also seen as the foot of consumption, It is the ability of the earth or the ecological system to produce the demanded stuff that is required for the existence and survival of the organisms, that compete for biological space. The term in short also is used to define biocapacity. This Also states the biological component to absorb the carbon content created by the organism The biological capacity in polar decreases and increases in trophic levels. Similarly, the oceanic productive and biological carrying capacity is impacted by this demand cycle. Related to the food chain and food web. Thus it's essential that this productivity is maintained and is needed as an energy source to absorb and recycle the wastes and pollution produced by continuous resource use. The primary productivity is measured by autotrophic level and secondary productivity is measured by heterotrophic level.Describe the roles of temperature and precipitation in determining what parts of the earth’s land are covered with:
(a) desert,
(b) arctic tundra,
(c) temperate grassland,
(d) tropical rain forest, and
(e) temperate deciduous forest.
Answer:
(a) Desert- In a desert environment, the temperature is relatively very high during daytime due to high absorption of sunlight and at night it again cools down. There is little or no precipitation here. This region includes the equatorial and some parts of the tropical region.
(b) Arctic tundra- This region lies in the higher latitudinal areas extending from the arctic to the extreme poles. The temperature here is extremely cold and precipitation is low. The plants and trees here are short in height.
(c) Temperate grassland- These are the mid-latitude areas covering the extensive grasslands of both the northern and the southern hemisphere. The temperature and precipitation level here are both moderate.
(d) Tropical rain forest- These are the regions that covers the vast rain forest areas in the tropical region of both the hemispheres. The temperature here is high is relatively high and high moisture content. As a result of which the rate of evaporation is high and rainfall is maximum. The region is rich in diverse trees and plants species.
(e) Temperate deciduous forest- These are the regions covering the mid latitudes that are rich in the deciduous forest. These are the dry forests comprised of various plant species. The temperature in this region is very moderate and summers are comparatively much cooler. Precipitation in this region is also quite moderate.
What caused Nordic countries to become more continental in the 1300s?
Question 1 options:
the development of democracies
new social classes
increased trade
industrialization
Answer:
increased trade
Explanation:
During the 1300's, the Nordic countries gradually became more continental. There was one major reason behind this process, that being the increased trade.
During this period, Europe and Asia became much more connected, and the trade was flourishing, bringing in lot of profit with it. While the Nordic countries didn't engaged in trade with Asia on a large scale, but mostly with the other European nations that were than trading those goods with Asia, they had to start offering quality and attractive goods in order to have their share from it.
This resulted in the people of these countries to become much more sedentary, and much less nomadic sea dwellers from what they were actually famous for. The people in this part of Europe started to engage into specific fields in which they were good at, and started to produce their own goods that were highly demanded on the market, so the population was becoming more concentrated and almost exclusively on the continent, not on the sea.
Answer:
increased trade

The type of the stream valleys formed in the mountains depends on the process of the flow of water as such the valleys that are formed are that of the V and U shaped forms and V-shaped valleys are usually found in the hills and the valleys pf the mountain ranges as these areas are affected by glaciers that make a U shaped flat valley bottom.The fossils of multicellular life forms observed in rocks a. are bones that have lithified into rock b. are found mostly in igneous rocks. c. are proof of the young age of the Earth. d. are no older than ~600 million years.
Answer:
d. are no older than 600 million years
Explanation:
Life on Earth appeared relatively early and in very hostile conditions, approximately 3.5 billion years ago, which is only 1 billion years after the formation of Earth. For the first multi-cellular animals to occur though, it took a very long time since life occurred, as the fossils suggest that they only appeared around 600 million years ago, whole 3.9 billion years later than the first uni-cellular lifeforms on Earth. Once the living organisms managed to get to a faze where they are multi-cellular, a real explosion in diversification of the living organisms occurred, and the evolution was rapid. Very soon complex organisms start to appear around the planet, eventually leading to the plants, fish, insects, sinapsids, dinosaurs, mammals, reptilians.

Which of the following is typically found in a developing nation?
strong technological base
lack of industrialization
highly diversified economy
advanced social programs
Answer:
lack of industrialization
Explanation:
The developing nations are nations that are classified as nations with low development. This type of nations are usually poor, their economies are not in good condition, there is lot of corruption, and the people often don't have most of basic means for life at disposal.
Another major characteristic of these nations is the lack of industrialization. Very often, these nations have economies that are based on agriculture, but agriculture that is practiced in primitive manner and there is only one major or just few products that are being produced.
These nations tend to stride toward industrialization, and the developed nations are helping them with funding and investments. Unfortunately, the large scale corruption is hindering this process, and these nations tend to stagnate instead of move forward.
Suppose that Earth’s interior contains a large amount of lead. Based on your prior knowledge, how dense is lead? Would the lead be more likely to be found in the crust, mantle, or core?
Answer:
Lead is one of the important elements found on earth. They are metallic gray in color and one of the heavy metal. It has a density of about 11.34 g/cm³. It has a high density because of its closed type of packing and face-centered cubic structure. Lead rarely occurs in its pure form on earth. It is mostly found to be present in association with its principle ore known as galena.
Thus, lead is a very denser element as it has a very high density.
In a situation where there is a huge amount of lead in the earth's interior, the lead will be most likely to be found in the core of the earth. It is because, in the present scenario, the core of the earth is comprised of denser elements namely iron (Fe) and nickel (Ni) that have an extremely high density.
Suppose that the hypothetical country of Kernaland suffers from chronic scarcity of its staple grain, corn. True or False: The country of Kernaland must be a developing country, since scarcity is not a problem in developed countries.
Answer:
False, Not necessarily
Explanation:
According to the question,Kerneland suffers from a chronic scarcity of its staple grain, and corns which are agricultural products don't mean that a country is not self-sufficient in itself. Since Kernaland faces this scarcity it can import the same products from other countries to get rid of this problem which maintaining a balance of trade it can export what it specializes with. Developed countries have had similar problems of food scarcity in the earlier periods, but have overcome this. Blaming developing countries from the lack of food supplies is not a good way of understanding the economy, as many nations that are now developed or food sufficient had to import more of agricultural produce example is landlocked countries.Large cities are fewer in number and farther apart than medium-sized cities; medium-sized cites are fewer in number and farther apart than small cities. What theory accounts for the regularities of size and spacing of cities as market centers?
Answer:
Rank size rule of cities given George zipf
Explanation:
It is a distribution of cities based on ranking their sizes as compared to others. This law states that there exists a remarkable regularity in the distribution size of cities and businesses, this ranking is also influenced by the population living in the cities. Thus farther apart cities tend to have a smaller size and varying further as the spacing grows. The main cause that leads to the growth of cities is there power to attract customers like centers of economic growth. like a city with rank three would have one-third the population of a country's largest city, ans a rank four city would have one-fourth the population of the largest city.Slang includes the formal aspects of a language.

In what ways is globalization of culture manifest in the landscape?
Answer:
Globalisation of Culture refers to the growth and spread of material culture from the place of origin to far and wide around the globe.
Explanation:
As culture includes transmission of ideas, beliefs, moral values and ethics. As globalization and integration of society, and spreading of the culture around the world through the international travels across national borders. As have modified culture according to there needs similarly they have modified their environmental settings so that it now hosts of manifestation or imprints on the landscape. The cultural changes across the globe have manifested itself the landscape's the globe and keeping this in mind UNESCO has classified many places son to earth as world heritage sites. Like Rice Terraces of Philippine Cordilleras, Matobo Hills, Zimbabwe, and Lavaux Vineyard Terraces, Switzerland are a few examples.Final answer:
The globalization of culture is manifest in the landscape through the proliferation of global brands, architecture, and consumer products that create a homogenizing effect on local cultures. This is evidenced by the presence of fast-food chains, technology stores, and fashion outlets originating from different parts of the world but found ubiquitously across various countries, thus contributing to a global cultural landscape that overlaps with local traditions and practices. Additionally, certain architectural styles and urban planning approaches, despite their foreign origins, become part of the local landscapes, reflecting a blend of globalization and local adaptability.
Explanation:
Globalization is an expansive term that pertains to the interconnectedness of the world through various forms of exchange, including cultural exchange. The cultural landscape, which encompasses architecture, economy, clothing, and entertainment, is a direct manifestation of the local resources and cultural adaptations of a community. The influence of globalization on these landscapes can be seen in the spread of common architectures like skyscrapers, shopping malls, and the presence of global brands in local markets. Moreover, localization or 'glocalization' also plays a part where global influences are adapted to fit local tastes and preferences, creating unique hybrid cultures. These changes are part of a broader conversation around globalization's effects, which are studied to better understand and navigate the ongoing transformations within cultural landscapes. Responses to globalization, such as syncretism and alternative market participation, demonstrate the agency of local cultures in redefining their landscapes amidst global influences.
The Nomadic Bedouin have lived in the Negev for centuries, and they have laid claim to large tracks of southern Israel. Currently the Bedouin are in dispute with the government of Israel over land use. The Nomadic Bedouin claim the government of Israel wants to use the disputed land for what purpose?
Answer:
Nomadic Bedouin are nomads that live by rearing livestocks having claims to large tracts of land the government of Israel is trying to remove them so that the land can be used for immigrants.
Explanation:
The Israeli prime minister David Ben oppose the movement of Bedouins from Jordan and Egypt as he wanted them to change their minds as the lands were nationalized and the area was kept for military ground as the government saw Negrev as the potential area for Jewish immigrant population. In 1951, the United nation reported the removal of 7000 bedouins from the Gaza strips. As they considered most of the grazing to be illegal, also the environmental leader Alon Tai claimed that the bedouins constructed environmental hazards in Israel as a result of soil erosion. Apart from this, they wanted to convert the land for industrial uses, for commercial uses and also for agricultural uses and onset of the urban settlements.What prefix is derived from the Greek word for earth?
Answer:
Ge or Geo
Explanation:
The Greek root word ge, commonly used in the English prefix geo-, means “earth.”
The prefix derived from the Greek word for earth is 'geo-,' which is used extensively in scientific terminology, including in various disciplines that study the Earth.
Explanation:The prefix derived from the Greek word for earth is geo. The usage of Greek and Latin in science and academia is prevalent due to their historic role as languages of the educated class. Those ancient languages provide foundations for many words used today in various fields like science, law, and philosophy. In particular, many metric prefixes that we use to denote different sizes of measurements in the SI system, such as kilo-, centi-, and mega, are derived from Greek or Latin.
In the context of the earth and sciences related to it, geo- is commonly used. For instance, 'geology' is made up of 'geo-' meaning earth and '-logy' meaning the study of, together referring to the study of the Earth's physical structure and substance.
Thermal (contact) metamorphism occurs ________.
a. only where gneiss is in contact with schist
b. only at the surface, where rock is in contact with the atmosphere
c. as a consequence of the sinking of a broad region to great depth
d. in areas surrounding igneous intrusions
Answer:
Option (D)
Explanation:
The contact metamorphism is a type of metamorphism which usually occurs around an intrusive igneous body. The temperature of the adjacent rock increases due to the intrusion of hot molten magma. The area that surrounds this intrusive body forms a ring which is typically known as the metamorphic aureole. The rocks that are commonly formed due to this type of metamorphism is hornfels. This rocks are mostly fine-grained and they do not indicate if the deformation is strong or weak.
Thus, this type of metamorphism generally takes place in the areas surrounding an igneous intrusion.
Hence, the correct answer is option (D).
Thermal or contact metamorphism occurs in areas surrounding igneous intrusions, where the heat from magma transforms surrounding rocks into different types of metamorphic rocks.
Explanation:
Thermal metamorphism, also known as contact metamorphism, occurs in areas surrounding igneous intrusions. It is caused by the heat from the magma invading the surrounding solid rocks. The pre-existing rocks, due to this heat, are transformed into different types of metamorphic rocks. It does not occur solely where gneiss meets schist, at the surface where rock comes into contact with the atmosphere, or as a result of a broad region sinking to a great depth.
