Answer:
Option (4)
Explanation:
The lithosphere represents the outermost hard layer of the earth. This layer provides all the necessary elements for life to exist and these are available to all the living creatures in the form of soils. The lithosphere is comprised of the crust and the upper part of the mantle. The lithospheric crust on earth is divided into 2 types, namely the continental crust and the oceanic crust. These crusts move over the less dense layer of the asthenosphere, which covers a small portion of the upper portion of the mantle. This motion of plates is due to the convection current that generates in the mantle.
The rocks in the lithosphere are hard and it breaks during deformation.
Thus, the correct answer is option (4).
Asesthnosphere consist of the uppermost part of the mantel.
What forms the upper layer of planet earth ?
Earth is a planet in the solar system that supports life and has layered the earth is a dominant planet that is capable of supporting life. The earth is thus the rocky planet and is layers that support the earth are called the crust, core, and mantel.
As the asthenosphere is a sphere that divides the earth from the crust and core the layer has various properties.
The asthenosphere is a major layer and consists of more than 60% of the earth's mass. This layer holds the crust as crust freely floats on this layer.
Thus the answer is B.

At local solar noon in the northern hemisphere, the sun is south. Which way do shadows point at noon?
Answer:
The sun tends to rise from the eastern direction always and sets in the western direction. In the northern hemisphere, during the noontime, the sun reaches the center of the horizon and is directed towards the southern side. This means that when a person faces the sun at noon, by walking directly towards it, then it will let him move in the southern direction.
Thus, If one walks with the sun at his/her back, then it means that he/she is heading towards the north. Whereas, if a one moves with the sun at his front, then this means that the person is heading towards the south. The opposite case arises in the Southern Hemisphere.
In the northern hemisphere, the shadow moves from the western to eastern direction, and it points the north direction at noon. In the southern hemisphere, the shadows indicate the south direction at noon.
Final answer:
At local solar noon in the northern hemisphere, shadows point north as the sun is positioned in the southern sky. This is the underlying principle for how sundials operate, where the shortest shadow of the day points north at noon.
Explanation:
At local solar noon in the northern hemisphere, when the sun is in the southern sky, shadows always point away from the Sun. Therefore, shadows point north at noon. This phenomenon occurs because the Sun's position in the sky is to the south, casting shadows in the opposite direction. This principle is also the basis for how sundials work, with the shadow of the gnomon indicating the time of day. During the summer solstice, for instance, the gnomon's shortest shadow at solar noon points directly north, showcasing the Sun's highest position in the sky over the course of the year.
The climatic shift that was a major contributing factor to the collapse of the Viking colonies is known as the ________ ____ _____
Answer:
Greenland Norse collapse
Explanation:
The southern Greenland Vikings numbering 5000 at their peak never gave up their old way of lifestyle and did not adopt that of the Northern Inuits who arrived a century later after them. The study suspects that the climate factors became dominant and they were destroyed by the shifting nature of mother earth hence they starved to death and could not adapt to the present change in weather patterns this society collapsed. Some theories say soil grazing and over-exploitation of land lead to the effect of black deaths and the creation of ice age. It indicated that the number of fertile women dropped and thus population could not sustain itself.The symbolic nature of culture:

Why does hardness increase with shorter distances between the metal and the oxygen?
a.
The metallic bonding is optimal when the distances between the metal and the oxygen are the smallest.
b.
The electrostatic forces are the strongest when the metal and oxygen are closest together, making the compound harder.
c.
The chemical repulsion is the greatest when the metal and oxygen are closest to each other, making the compound harder.
d.
The magnetic attraction is the strongest when the metal and oxygen are closest together, making the compound harder.
Answer: Option (A)
The metallic bonding is optimal when the distances between the metal and the oxygen are the smallest.
Explanation:
Hardness increases with respect to shorter distances between the metal and the oxygen compounds, the reason for the increase in hardness is due to metallic bonding (electrostatic force between electrons and positive ions) which is optimal between them.
As the distance decreases, hardness increases and for increasing distances hardness decreases. So when the molecular weight is large, it has smaller valence or less charge on the metal which makes the bond weaker and less hard.

What factors made the study of traditional Native American music difficult for the ethnomusicologists who were interested in researching it?
Answer and Explanation:
Native american don't have any melodic hypothesis to give data with respect to their melodic traditions.Their music is fundamentally vocal and non-instrumental this makes measure of data present in open circle even less.Also local american culture has been hurt and devastated by non-locals, as America was settled essentially from European and African pilgrims
So generally we rely upon records of European Scholars with respect to the history and culture of local Americans.These European researchers had distinctive taste of music, so records of these researchers are misshaped. That is the reason it is hard for the ethnomusicologists to examine the local american music.
1) Joints differ from faults primarily
with respect to the types of deformation that form them
with respect to strength of the rocks
whether displacement has occurred
the amount of weathering to which they are prone
2) The law of cross-cutting relationships pertains to the age relationships in a sequence of sedimentary layers.
True
False
3) Neutrons add charge, but not mass, to an atom.
True
False
Answer:
1- Option (C)
2- TRUE
3- FALSE
Explanation:
Joints are the type of fracture that splits the rock into two parts thereby the blocks move away from one another. They are formed due to the tensional force. Whereas, the fault, in simple terms is defined as the cracks or fractures present in the crust of the earth. They are formed by both tensional as well as compressional forces. They differ from one another in terms of displacement. In a fault, the relative displacement between the blocks is more than in the case of joints.
According to the law of cross-cutting relationships, geological features such as faults, igneous intrusions, that cuts across the sedimentary layers on earth are younger than those sedimentary rocks.
A neutron is a neutral particle as it does not carry any kind of electric charge. So, the addition or elimination of neutron from the nucleus does not affect the electric charge of the nucleus. But it can cause changes in the mass within the nucleus. Isotopes originate due to the addition or removal of neutrons from a nucleus.
Hence, the correct answers are given above.
The majority of glaciers on planet earth are in either or regions
Answer:
Majority are on continental regions
Explanation:
Moat of glacial ice and ice caps are found in polar regions of the earth as they are home to permanent frosting and valley glaciers in the interior of the continents like in Asia, Africa, and other countries are not so much developed as they tend to stagnate or be limited due to the landmasses characteristics. Greenland and Antarctic glaciers together combine and makeup 99% of the freshwater reserves and ice on earth. As they were spread over a large surface of the earth the Antarctic glacier covers 25,400,000 km on the surface. These glaciers produce a thick mass of ice as compared to the valley glaciers which are unstable and have braided streams. Being characterized by retreating glaciers, and having an average mass of 4%.explain effects of different fire regimes on total soil carbon and organic carbon and dissolved organic carbon.
Answer:
Explanation as below.
Explanation:
As soil is composed of organic matter that includes the carbon contents, the fire regime leaves a bad impact on the soil nutrients such as bleaching of nutrients and minerals, also the crop fires are a common type of regime followed in various vegetation clearance practices. The dissolved soil organic content includes acids, fats, sugars, proteins, enzymes, and hydrocarbon fuels. As all organic matter consists of carbon , inorganic carbon is extracted from ores and minerals. DOC is abundant in minerals and freshwater. Also, forest fire on shrublands kills bacteria and fungi in soil surfaces. Loss of soil matter and increased bulk density can decrease the water keeping the holding capacity of the soil. Surface erosion by wind or gravity can also increase when ground cover.What are some of the environmental issues in Mexico that could contribute to poor health and economic problems? Can you explain ways you'd solve those issues also?
Answer and Explanation:
Some of the major factors for the environmental issues in mexico are:
1. Contamination of the environmental resources and the degradation of the level of oxygen as a result of the cutting down of forests and natural habitats loss.
2. Chemical contamination because of deceptive release of the material leaving the industrial facilities and exploitative dumping.
3. Increment in the population growth resulting from migration of people from other counties, lower Infant Mortality rates, better life expectancy of the residents as a result of good nutritional intake.
All these factors results in the increase in the basic needs of the people thus requiring more land and hence clearing of trees and land area.
Mexico should build the quantity of biosphere reserves and should center ecotourism for protection of its tendency.
Alongside this, they have to center populace control measures to be aware of population development. They should likewise turn out to be a piece of worldwide ecological projects that concentrates on the factors to safeguard our environment and should pay attention to the IPCC rules. They should join Convention on International Trade in Endangered Species (CITES) likewise and should stay up with the latest elements of the world. Aside from this, they ought to likewise do legitimate Environmental Impact Assessment before beginning of a formative undertaking.A long time ago, sailors recognized the lack of wind in the ITCZ and dubbed the region the"doldrums". What other situations can you think of where sailors made discoveries that are now justified by modern science?
Answer:
"Doldrums" also called as he Horse latitude.
Explanation:
The equator is generally considered as the region of calm later on it was called the ITCZ. Now its called the doldrums as the belt of the equator which houses the Hadley cells. This is marked by the zero degrees latitude and this zone is the zone of mixing of atmospheric trade winds, earlier times sailors who came at this place along with their ships and horses but had to experience long-lasting high velocity prevailing winds at an altitude of 30, 40, 50, 60 degrees. So they named these winds on these altitudes as the forties, screaming sixties filtering fifties. These winds were so strong that their ships used to get drowned with horses in these latitudes. These were the discoveries made by the sailors.Answer these questions: (3 to 8 paragraphs for each question)

6. What is dark energy? How much of the universe is thought to be dark energy?
Answer:
The dark energy is one of the primary composition of the universe, which is not visible and are mysterious. as a very little is known about this energy. This dark energy makes up nearly 68% of the universe. It is often considered as a property of space. The presence of dark energy can be detected as it affects the expansion of the universe. The universe started to form right after the big bang explosion and since then the space is expanding in all direction. With this, the dark energy present in the universe also is expanding at a considerably faster rate in association with the Cosmic Microwave Background (CMB) radiation. The measurements of the distance and their connection with the redshift provided an evidence that the universe has been expanding at a certain speed.
One of the reasons ______ environments tend to be warmer than _______ is that _______ surfaces tend to be covered with buildings and roads which have low albedo
Question 60 options:
urban, rural, urban
continental, rural, continental
rural, urban, rural
maritime, rural, urban
The correct answer is A. urban, rural, urban
Explanation:
In general terms, the temperature is related by multiple factors that include the altitude, latitude, weather, among others. Besides this, it has been found the temperature of the same geographical zone can vary depending on whether the zone is urban or rural. In this way, rural zones can be 1° to 3° grades hotter (even up to 7° grades) that urban zones, this can be explained as in urban zones surfaces are covered by roads, buildings or similar instead of trees, grass or lakes, and these type of artificial structures tend to absorb heat but not reflected which refers to the albedo. Thus, urban environments tend to be warmer than rural because urban surfaces have a low albedo.

a common misconception about earth's mantle is that it is a
thick layer of molten rock. Explain, in your own words, why Earth's
mantle is actually solid under normal conditions.
Answer:
Lava or magma is considered to be in molten state while the earth's mantle is layer of rocks that changes its state
Explanation:
Earth's mantle is composed of solid rocks that exist in a liquid form, the upper layer is that of the Asthenosphere and the layer of the mantle is further divided into upper, lower and transitory layers. Being the massive and most widely occurring layer covering the planet. It has a layer of silicate between the crust and outer core. It is approximately 1600 km thick. The upper mantle contributes to the tectonic activity as the rocks in this layer are malleable. There are 15 major and minor slabs above the layer and lava i.e the molten rock is burned inside the magma at grater depths and as there exists water in the mantel the transition zone is evident from the upper and lower exchange of minerals.Select all of the correct answers: AU is:

a measurement of distance
the distance from the center of the Sun to the center of the Earth
Explanation:
Astronomical unit ( AU )
The value of 1 astronomical unit ( AU ) = 92,955,807 miles or 149,597,871 km , which is equivalent to about 150 million kilometres . it is the average distance between the sun and the earth .
It is used as a measurement unit , for the solar system , the AU , measures the distance , hence its units are miles , km etc .
Final answer:
An Astronomical Unit, abbreviated as AU, is the average distance from Earth to the Sun, used primarily to measure distances within the solar system, and is about 150 million kilometers. (First and fourth options)
Explanation:
An Astronomical Unit (AU) is the unit of length defined as the average distance between Earth and the Sun. This distance is about 150 million kilometers (93 million miles) or precisely 149,597,870.7 kilometers. The AU is commonly used to measure distances within the solar system, making it a fundamental concept in astronomy.
The statements regarding the AU as a measurement that varies depending upon the time of year or as being the distance from the Earth to the Moon are incorrect. While the Earth-Sun distance does vary over the course of a year due to Earth's elliptical orbit, the AU represents the average of these distances.
Moreover, the distance from Earth to the Moon is measured in Earth-Moon distances, known as lunar distances, not in AUs.

Why is the June solstice associated with the Southern
Hemisphere?
Answer:
June solstice marks the beginning of summer in southern hemisphere, due the earth rotational motion and reverse properties of the both hemispheres.
Explanation:
The summer solstice is associated with the midsummer, occurs when the earth poles are the maximum inclination to the sun. A within the antarctic hemisphere there is continuous daylight as the maximum axial tilt is around 23.44 degrees. Depending on the shift of the calendar days the summer solstice occurs around Dec 20 and 23rd of the year. This is due to the earth moves in an elliptical motion. In the southern hemisphere, the sun moves from East to West. It contains about 60.7% of the water on the earthA water quality standard recognized in British Columbia for Zn

What are the principal sedimentary rocks? What is the genesis (origin) of each sedimentary rock type?
Answer:
The sedimentary rocks are those that are formed due to the compaction and lithification of sediments. Some of the examples are shale, mudstone, sandstone and limestone.
This sedimentary rocks are divided into 2 principle types. They are as follows-
(1) Clastic sedimentary rocks- This type of rocks are formed when the rock particles are weathered physically from the terrestrial rocks (source area) and are transported from one place to another by means of wind, water and ice. These rocks are named depending on the size of the sediment particles. Conglomerates and sandstone are examples of clastic sedimentary rocks.
(2) Chemical (Carbonate) sedimentary rocks- This type of sedimentary rocks are formed due to the precipitation of certain minerals from water. Due to this precipitation, the water releases the dissolved minerals. Some of them are also comprised of carbonate minerals that precipitates when reacts with water. In addition to that, some fragments of marine fossils are also found to be accumulated in this type of rocks. For example, rock salt, halite, dolomite, chert and limestone.

4. Explain the global timekeeping system. Mention standard time, standard meridians, and time zones in your answer.
Answer:
Answers given below.
Explanation:
Earth is not a perfect sphere but a geoid or elliptical, some claim that distance of the sun and rapid spinning of the earth on its axis from the equator to the poles is narrowed downwards. Effects of this rotational motion influence the seasons and oceanic currents and wind patterns. The angle of inclination that the sun makes with the earth is also affected due to the tilt and hence there is uneven heating of the earth at various altitudes. As the aspect of positive map projection is that it helps in navigation such as that of the Mercators projection but it distorts the upper spheres of earth and the Googe projection is an equal-area projection used in multiple worldwide interruptions also called as homolographic projection. Guillaume Postel created the polar projection used it represents the north polar regions. Its drawbacks are that the southern hemispheres of the map are distorted heavily. The time zones for the northern hemisphere and southern hemispheres are divided from the UTC points in Greenwich England.QUESTION 5 What is a Platonic Idea? A. Sensible forms within things B. An immaterial and intelligible form of sensible things C. The traditional gods that moves sensible things D. A human thought about sensible things
Answer:
B. An immaterial and intelligible form of sensible things
Explanation:
Platonic Idea -
It is given by Plato ,
He proposed this theory via the concept of eternal form , according to this theory , the immutable essence that can only be participated in the sensible things .
The idea is an invisible reality , an eternal thing , an immaterial and the prototype of the reality .
A Platonic Idea refers to an eternal, immaterial form of sensible objects, as conceptualized by the Greek philosopher Plato. These forms stand in contrast to the physical, changeable realm and are considered the true essence of things. Plato believed that understanding these forms is the key to wisdom, justice, and courage.
Explanation:A Platonic Idea, according to the Greek philosopher Plato, is an immaterial and intelligible form of sensible things, which gives them their identity. These forms critically differ from the ever-changing realm as the forms exist eternally in the invisible realm that Plato conceived. They shape our perception of reality, but are not subject to the change and decay that physical objects experience.
In contrast, Aristotle's philosophy focused more on the four causes, the material basis of things, instead of the immaterial forms. This material basis includes matter, form, agent of change, and the aim or purpose of things.
Plato further argued that virtue and understanding are derived from accessing the realm of the forms. That is why he proposed the idea of philosopher-kings who have the deepest understanding of the forms.

Explanation:
Specifically, it alludes to the steady move in the direction of Earth's pivot of revolution, which, similar to a wobbling top.
The expression precession regularly alludes just to this biggest mainstream movement; different changes in the arrangement of Earth's pivot - nutation and polar movement - are a lot littler in greatness.
What is geology? Why is it important that everyone have a basic understanding of geology, even if they aren't going to become geologists?
Answer:
Geology refers to the study of the earth's physical and chemical processes, how they occurs and what are its effects. It explains how the earth has formed over millions of years. It also describes the internal structure of the earth and the study of the rocks and its minerals. It is a vast subject that is related to physics, chemistry, and biology.
The basic concept of geology must be known to all because earth undergoes various changes with time. Some of the events that occur at different places on earth are earthquakes, tsunamis, floods, hurricanes and so on and the conditions under which these processes occur must be known to all. It provides an idea of how to be away from such destructive processes.
Thus, geology is a very important subject and one must have basic knowledge about it.
question 55:
As the altitude increases, the temperature of the atmosphere decreases in this layer of the atmosphere.
I. Troposphere
II. Stratosphere
III. Mesosphere
IV. Thermosphere
Question 55 options:
I and III
II and III
I and II
II and IV
Answer:
Option (1)
Explanation:
The atmosphere plays an important role in controlling the earth's climate. This atmosphere is comprised of different layers. They are as follows-
(a) Troposphere- This layer extends up to a height of about 10 km from the ground surface. In this layer, the temperature and altitude are inversely proportional to one another. This decrease in the temperature with increasing height is known as the Lapse rate and is 6.5 degree C/km.
(b) Stratosphere- This layer is present above the troposphere. It extends from about 10 to 50 km above the surface. Here, the temperature increases with height. It is because of the presence of ozone in this layer that warms the layer.
(c) Mesosphere- This layer is above the stratosphere and below the thermosphere. It extends vertically from about 50 to 80 km above the ground surface. The temperature again decreases with height in this layer.
(d) Thermosphere- This layer forms the outermost layer. Here, the temperature and height are directly proportional to each other.
Thus, the temperature decreases with altitude in the layers, namely the troposphere and the mesosphere.
Hence, the correct answer is option (1).

The rocks adjacent to the Mid-Atlantic Ridge are older than those further away from the ridge.
Answer:
Option (2)
Explanation:
The mid-oceanic ridge is the region along which the sea floor spreading takes place. It forms a divergent plate boundary. Here, the magma forces to come out to the surface, by stretching and thinning the lithosphere. These magma as it comes out to the ocean floor along this mid-oceanic ridge, it immediately cools and form rocks that are basaltic in composition and lavas are formed. The Mid-Atlantic ridge is an example of mid-oceanic ridge.
According to the given condition, the solidification age at the Mid-Atlantic ridge is given. This indicates that the rocks that last crystallized 10,000 years ago at the Mid-Atlantic ridge are the youngest rocks.
Hence, the correct answer is option (2).
