Answer:
Wegener gave many evidence to the theory of plate tectonics another piece of evidence was the finding of fossils of reptiles in oceans and glossiperious fauna and the similarity of glaciers in all continents
Explanation:
Alfred Wegener is supposed to believe that the supercontinent named Pangaea consisting of northern continents and the southern continent i.e Gondwanaland consisting of southern continents were once the same. Thus he gave evidence in the shape of puzzle-like fit of the continents as similarity of rocks found in the continent's of Africa and South America, as they were one earlier. Further, he gave the supporting pieces of evidence as the glacier landmasses distributed were the same part earlier drifted away from the larger continent of Greenland. The supporting evidence the put forth was the polar wandering forces that he called the flight from poles and drift under the impact of moons gravity and another evidence was the thin sheets or plate moved away due to the wind.Another key evidence for Wegener's hypothesis of continental drift was the similarity of fossils found in different continents, which suggested these continents were once joined.
Explanation:Wegener proposed that the similarities between fossils found only in South America and Africa indicated that these two continents were joined at one time. This idea was part of his larger argument that the continents were once connected in a supercontinent he called Pangaea. He supported his claim by pointing out the resemblances among living animal species on different continents, and asserted that these similarities could best be explained if the continents were once connected.
However, Wegener's idea was initially met with resistance due to a lack of a clear mechanism. The discovery and understanding of plate tectonics years later provided this missing piece, ultimately confirming Wegener's hypothesis and establishing it as a central viewpoint in our understanding of the Earth's dynamic nature.

Having an average density of 2,7 g/cm, primarily being composed of denser rocks like basalt and gabbro from below. Mostly it's basaltic, from here all sorts of rocks are recycled to the outer land surface of the earth. Accounting for nearly 60% of the global slab of plates. Apart from this, the seafloor is covered with volcanic necks, trenches and deep-seated volcanoes that produce magma and the oceanic floor is composed of layers of rocks that date back to the various epi, meso, bathy, and abyssopelagic divisions.PLZ HURRY IT'S URGENT!!
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.
Although greenhouse gases likely account for the problem of global warming, they are also responsible for making earth habitable. What would be the temperature on earth in the absence of the effects of carbon dioxide and water?
Answer:
-18°C
Explanation:
Global warming takes place due to the constant increment of atmospheric gases caused by human activities, and these include CO2, CH4, N20, and CFC. These are commonly known as greenhouse gases because they allow for the major part of solar radiation to enter the atmosphere and heat the surface of the Earth. At the same time, they avert a part of thermal radiation from escaping to space. If these effects caused by greenhouse gases and water did not exist, the average temperature of the Earth would be around -18°C (0°F), but instead, it is about 15°C (59°F).
Which of the arrows on the climate map above is pointing to the Sahel, the semiarid region bordering the Sahara Desert? A. One (1) B. Two (2) C. Three (3) D. Four (4)
The Sahel is a region in Africa that is located along the southern part of Northern Africa. This region is a natural transitional zone between the deserts on the north and the savanna and tropical forests on the south. The Sahel stretches roughly in an east-west direction, from the shores of the Red Sea to the shores of the Atlantic Ocean.
The climate in this area is semi-arid. The temperatures are hot all year round, the precipitation levels low, though higher than the desert, and it is relatively windy. The landscape is rocky and the vegetation that dominates is of steppe type.
The countries through which the Sahel passes are Senegal, Mauritania, Mali, Burkina Faso, Algeria, Niger, Nigeria, Cameroon, C.A.R., Chad, Sudan, South Sudan, Eritrea, and Ethiopia.

Consider the following processes: respiration, combustion, polymerization, nitrification, industrial fixation, and photosynthesis. How many of these result in the release of oxygen into the atmosphere?
Answer:
The answer to the question "How many of the processes result in the release of oxygen into the atmosphere?" is only one of them does it: photosynthesis.
Explanation:
The photosynthesis occurs mostly inside plants. During this process, the plant needs carbon dioxide, light and water in order to release oxygen into the atmosphere.
The respiration is a process where oxygen is consumed and carbon dioxide is released into the atmosphere.
The combustion involves two participants: a fuel and an oxidizer. During this process, oxygen is consumed too and new chemical substances are created. Also, it generates heat during the process.
The polymerization is a process where simple molecules form chains and become more complex and bigger molecules. There are different types of this reaction and some of them use oxygen when they are forming bigger molecules. To conclude, this process do not release oxygen into the atmosphere.
The nitrification is a process that is made mainly by bacteria. During this process, those organisms need to use oxygen from the environment to be able to transform ammonia to nitrate. This is an important step to enrich the soil, but it do not release oxygen.
The industrial fixation is not a natural process. During this synthetic reaction, atmospheric nitrogen is transformed into nitrogen oxides or ammonium ions that bacteria can use in nitrification. It consumes oxygen too.
Final answer:
Out of the processes listed - respiration, combustion, polymerization, nitrification, industrial fixation, and photosynthesis - only photosynthesis results in the release of oxygen into the atmosphere.
Explanation:
During photosynthesis, plants convert carbon dioxide and water into glucose and release oxygen as a byproduct, thus enriching the atmosphere with oxygen. The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + Light Energy
ightarrow C6H12O6 + 6O2, clearly showing the production of oxygen. None of the other processes mentioned, such as respiration, combustion, or nitrification, release oxygen; in fact, they consume oxygen and produce carbon dioxide. Respiration is the process where organisms use oxygen to break down glucose into carbon dioxide and water, releasing energy. Combustion is the burning of substances in oxygen, resulting in the release of carbon dioxide. Polymerization does not involve any exchange of gases with the atmosphere. Nitrification is part of the nitrogen cycle where ammonia is converted into nitrite and then nitrate, and industrial fixation, similar to the Haber process, is about synthesizing ammonia, neither contributing to atmospheric oxygen.

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.To test Copernicus’s model, Tycho took meticulous measurements of the positions of the planets, and he hired Kepler to interpret the data. Kepler found that the geocentric model did not accurately predict the planets’ positions, but neither did Copernicus’s heliocentric model. He found that Copernicus’s insistence that the planets’ orbits were perfectly circular was the problem. If the orbits were instead ellipses, then the heliocentric model would have been able to very accurately predict the positions of the planets. This is known as Kepler’s first law of planetary motion.
A. Elliptical orbits cause a planet to sometimes be closer to and sometimes farther away from the Sun.
B. The Sun is located at one focus of a planet’s elliptical orbit, and the planet is located at the other focus.
C. Halley’s Comet has a highly eccentric orbit.
D. The Sun is located at the center of a planet’s elliptical orbit.
E. The eccentricity of Mars’s orbit is zero.
The question discusses the historical breakthroughs in understanding the solar system, notably by Copernicus followed by improvements by Kepler. Misconceptions about the shape and nature of planet orbits (eccentricity and elliptical shape) are the main theme. Not all given statements about planets' orbits are correct.
Explanation:The subject matter in this context is primarily talking about the work of Copernicus and the discovery of better understanding of the solar system through the concepts of orbits. Terms like 'eccentric' and 'elliptical' orbits are being used which reference to the shape of the paths that planets follow around the sun. Statement A, B, and C are correct and based on Kepler's first law of planetary motion. Option B is not correct because it's not the sun and the planet that constitute the foci of the ellipse but the sun and an empty point in space. Option D is not correct because the sun is not at the center of the elliptical orbit but at one focus. And statement E implies that the Mars's orbit is a perfect circle - which is untrue, since no planet has a perfectly circular orbit; all planets have orbits with a certain degree of eccentricity.

Which of the following is correct?
a.The age of the seafloor decreases as you move away from the mid oceanic ridge
b.The age of the seafloor increases as you move away from the mid oceanic ridge
c.The age of the seafloor is the same in most areas
d.The age of the seafloor does not follow a discernible pattern
Answer:
A. The age of seafloor decreases as you move away from the mid oceanic ridges.
Explanation:
The scientist can determine the age of the seafloor by evidence collected by dating the rocks found near the seabeds, the rocks that were found far away from the mid-oceanic ridges and seafloor were considered to be of the old or ancient period as compared to the rocks that were seen near the surface of the ridges. This is because the spreading of lavas, on or near the surface of the ridges creates lava plumes that tend to move up and these on cooling down get settled with the same magnetic patterns or alignment that of earth. Thus distant rocks have different age compositions due to the molten matter that forms the basaltic rocks in tectonic plates.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.

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.

The temperate forest is the biome described. It is characterized by deciduous trees that create a thick layer of leaf litter, contributing to a rich nutrient cycle and ecosystem services such as filtering pollutants from water.
The biome that contains a nutrient-rich environment created by falling leaves and trapped organic materials from large trees, which provides the ecosystem service of filtering pollutants from water, is the temperate forest. In the temperate forest, deciduous trees dominate and form a thick layer of leaf litter on the forest floor when they shed their leaves. This leaf litter is crucial for maintaining a rich nutrient cycle and offering protection against soil erosion. Moreover, it insulates the ground and serves as a habitat for various invertebrates like the pill bug (Armadillidium vulgare) and their predators, such as the red-backed salamander (Plethodon cinereus). The nutrient cycle in temperate forests is characterized by the decomposition of the leaf litter, which returns inorganic and organic nutrients back to the soil, thereby enhancing its fertility and providing an integral ecosystem service by filtering pollutants from water.

You are halfway between the equator and the South pole and one-quarter of the way around the Earth to the west of the Prime Meridian. What is your latitude and longitude?
Answer:
All of the lines of longitude to the west of the prime meridian until 180 degrees are in the western hemisphere. Ninety degrees west is a line that passes through North America, including Lake Superior and the Yucatan Peninsula.
You are located at 45 degrees south latitude and 90 degrees west longitude, as you are halfway between the equator and the South Pole and a quarter of the way around the Earth west of the Prime Meridian.
If you are halfway between the equator and the South Pole, that means you are at 45 degrees south latitude, because the South Pole is at 90 degrees south latitude. When you are one-quarter of the way around the Earth to the west of the Prime Meridian, given that a full circle is 360 degrees, a quarter of that would be 90 degrees. Since you are west of the Prime Meridian, your longitude would be 90 degrees west. Therefore, your complete coordinates would be 45°S latitude and 90°W longitude.

Explanation:
The Earth rotates in its own axes, that is the reason why it can be observed the Sun and some other starts with the naked area. And apparently all the sky rotates, but actually is the planet the one that is constantly moving.
If the sun is close to Earth, so the light hours during the day are longer, and the visible of sun and stars is no so common.
When the sun is apart to the Earth, so the day hours are smaller, and the probability to observe the sun and the stars at the same time increases.
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.
