Answer: Niger
Explanation:
Its source is in the Guinea Highlands in southeastern Guinea. It runs in a crescent through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive delta, known as the Niger Delta or the Oil Rivers, into the Gulf of Guinea in the Atlantic Ocean.
Explain how convection currents are related to plate tectonics?
The convection currents are what causes the movement of the tectonic plates. These currents occur in the mantle layer. Basically, the convection currents are a circular movement of the magma in the mantle which is cause by the difference in temperature and density. The hotter magma moves up because it is less dense, while the cooler magma moves down because it is more dense. This movement continues all the time. The magma that moves up comes in touch with the crust above it. At certain places where the crust is thinner, or there are cracks, under the big pressure from the mantle, the magma manages to penetrate through it, filling up the gaps, and also pushing the plates away. As the plates are pushed more and more, their opposite ends collide with other plates, resulting in subduction, so the crust is getting into the mantle and melts, moving down in the mantle as it is becoming cooler and denser magma, and the process continues on and on.

Does the earth have an unlimited supply of magma?
Answer:
No
Explanation:
The magma supply of the Earth is not unlimited, but instead it has a fairly constant volume. On the other hand, the magma is not spending itself even though it constantly comes out on the surface of the Earth. The reason for that is that the magma that comes out on the surface, is actually replaced by newly formed magma. The newly formed magma is actually from the crust of the tectonic plates that are subducting. As the plates are subducting, they reach the mantle layer where the temperature and pressure are very high, so they melt the crust. The molten crust is becoming the new magma that replaces the one that is pushed toward the surface. This is a cycle that constantly goes on, so even though the magma is not endless, it manages to circle through the top two layers and replenish itself.

What are the four countries with the largest land areas in the western hemisphere?
Answer:
Canada, United States, Brazil, Argentina
Explanation:
The four largest countries by area in the Western Hemisphere are Canada, United States, Brazil, and Argentina. These countries are located in North and South America, with Canada and the United States being in North America, while Brazil and Argentina being in South America. All of these countries are in the top 10 largest countries in the world by area, with Canada being on the second place, the United States on third, Brazil fifth, and Argentina eight. One of the main reasons why these countries are so large is because they are countries of the New World, all being former colonies, where the populations where relatively small, but the European settlers managed to occupy very large areas. Once they gained independence, the boundaries were set in accordance to the colonial boundaries, so instead of having numerous smaller countries divided because of ethnicity, race, or culture, large multiracial, multiethnic, multicultural countries were established.
The four countries with the largest land areas in the Western Hemisphere are Canada, the United States, Brazil, and Argentina. Additional information is required to determine which country has the largest percentage of its land protected.
Explanation:In the Western Hemisphere, the four countries with the largest land areas are:
Canada: Spanning much of the northern part of North America, Canada is the second-largest country in the world by total area.the United States: Including the contiguous states as well as Alaska and the island state of Hawaii, the U.S. ranks third in the world by total land area.Brazil: The largest country in South America, Brazil ranks fifth in the world by total area.Argentina: Ranking as the eighth-largest country in the world, Argentina is South America's second-largest country by physical area.When considering the question of which country has the largest percentage of its land protected, this information does not provide a direct answer. We would need additional data on the protection status of lands within each country to answer definitively.

What does the line at 13600 represent?
scale bar
index contour
elevation difference
topographic symbol
Answer:
Index contour
Explanation:
A line on a map at 13600 would likely represent an index contour. On a topographic map, an index contour is a contour which is usually thicker and bolder with its elevation value written on it. Using this index contour and the contour intervals, we can estimate the values of other contour lines on the map.
The use of an index contour makes the map less crowded with symbols thereby making the map readable.
The answer is index contour, or the second option.

Explanation:
What three processes happen in every geological period? A. Mass extinctions, Wegenerian cycles, and the emergence of new life forms B. Climate change, Wegenerian cycles, and mass extinctions C. Mass extinctions, the complexity of life, and oceanic movement D. Wegenerian cycles, massive storms, and continent formation
Answer:
A. Mass extinctions, Wegenerian cycles, and the emergence of new life forms
Explanation:
Every geological period is characterised by episodes of mass extinction, Wegenerian cycles and emergence of new life forms.
The boundaries of most geologic periods are usually mass extinction periods and these mass extinction activates new evolution of life forms. For example, the period between the Mesozoic era and Cenozoic is marked by the K-T extinction where dinosaurs and about 75% of all life became extinct. New advanced mammals sprang up shortly after the extinction in the Cenozoic era.
During the geologic period, series of tectonic activities are in play as a result of the internal workings of the earth. Continents splits apart and new landform arises at plate boundaries. This is the Wegenerian cycle. The external processes like weathering and erosion helps to recycle the landforms and keeps it in check.
Brittany wants to use a model to study soil erosion on hills. She is told that farmers can prevent soil erosion by plowing so that their furrows run along hills instead of up or down hills. She fills a pan with dirt, packs the dirt firmly, then shapes it into parallel furrows. What should Brittany do with her pan of dirt next in order to study soil erosion? A. shake the pan rapidly back and forth B. prop up one end of it to make a slope and carefully pour water over it C. fill the pan with water, then tilt it until all the water runs out D. set it outside and check on it every day
Answer:
D. set it outside and check on it every day
Explanation:
In order for Brittany to be able to study the soil erosion by using a simplified method of what the farmers do on the slopes to minimize it, she will need to take the pan, leave it outside, and check on it every day. By having the required shape, the soil will give somewhat an example of the soil on the slopes that has been plowed so that the furrows run along the hills. Since the hills do not move or tilt, the pan with the soil should be stable, static. Being put outside, it will be exposed to the natural conditions that cause the erosion, such as the water and wind. Brittany will need to check upon the soil every day and make detailed notes and measurements to see what the erosive effects are on it.

A student wants to know if the bubbles on this water plant are oxygen gas
(02). However, identifying a gas as O2 with direct evidence requires many
kinds of equipment.
Which observation would provide indirect evidence that the bubbles are 0?
O
A. A measurement of the plant's growth over time
O
B. A description of the color of the light under which the plant is
growing
O
C. A description of the shape of the plant's leaves
D. A count of the number of bubbles produced by the plant in the
dark
Answer:
D
Explanation:
Plants produce oxygen as a byproduct of photosynthesis; The formulae for photosynthesis is; 6CO2 + 6H2O –(sunlight)----> C6H12O6 + 6O2
Therefore for oxygen to be produced, there has to be sunlight. An indirect way of determinig the gas is comparing the number of bubbles during the day and night. The bubbles should be more during the day than night.
In order to indirectly confirm that the observed bubbles on the water plant are oxygen, one could measure the amount of bubbles produced by the plant in dark conditions. If there's a significant decrease in bubble production in the dark, it suggests that the bubbles produced in light are oxygen, a byproduct of photosynthesis.
Explanation:The observed bubbles on the water plant could potentially be oxygen (O2) as a product of photosynthesis. In general, during photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using light energy. Therefore, observing the bubbles in water around a plant can be indirect evidence of O2 production if the conditions for photosynthesis are present.
The ideal observation would be to count the number of bubbles produced by the plant in the dark (Option D). This is because photosynthesis — the process by which plants convert light energy into chemical energy, producing glucose and releasing oxygen as a byproduct — doesn't happen in the absence of light. Therefore, if there's a significant decrease or complete absence of bubble formation in the dark, it would indirectly suggest that the bubbles being observed under light conditions are indeed oxygen, released during photosynthesis.

Are there more mountains east or west of the mississippi river
Answer:
yesExplanation:
There is only one major mountain range east of the Mississippi River (the Appalachians) but two major ranges west ( the Rockies and the Sierra Nevadas). The latter mountain ranges are relatively younger than the Appalachians and therefore have higher and sharper (and more) peaks.
The United States has more mountains to the west of the Mississippi River, including notable ranges like the Rocky Mountains and the Sierra Nevada. Comparatively, the East has fewer mountains, although it includes ranges like the Appalachian Mountains.
Explanation:The Mississippi River divides the United States into the East and West. Generally, there are more mountain ranges located to the West of the Mississippi River. Significant mountain ranges such as the Rocky Mountains and the Sierra Nevada contribute to this count. Although there are mountains to the east, such as the Appalachian Mountains, their count is not as abundant as the West.

What motivates many South Americans to move from rural to urban areas?
irrigation
the fact that mechanized agriculture has replaced manual labor
plantation farming
subsistence agriculture
Final answer:
The main motivation for South Americans moving from rural to urban areas is the search for better economic opportunities due to the replacement of manual farm labor by mechanized agriculture. Urban areas offer more jobs, education, and healthcare, while farming presents challenges like weather dependence and unstable markets.
Explanation:
Many South Americans are motivated to move from rural to urban areas primarily due to the promise of better economic opportunities. Mechanized agriculture has replaced much of the manual labor on farms, resulting in fewer job opportunities in rural areas. As a result, people often seek work in urban areas where industries and services provide more employment options. Furthermore, urban areas tend to offer better access to education, healthcare, and infrastructure. The challenges of farming, such as dependency on weather and volatile market prices, also make agricultural life less attractive, prompting a rural-to-urban migration. This historical trend of urbanization mirrors the global shift seen since the Industrial Revolution, where technological advancements and industrial growth have concentrated populations into growing cities.
What is the island in the atlantic off the northwestern coast of mainland europe?
The British Isles are an archipelago (Great Britain and Ireland, and other smaller islands) located at the northwest of the coast of Europe. They are separated from the European continent by the North Sea to the east and by the English Channel to the south, while to the west and north they border the Atlantic Ocean.
However this was not always in this way. Millions of years ago this portion of land was a peninsula linked by a limestone mountainous ridge to mainland Europe. This is how, where the current Dover Strait is located, there was a rock formation that joint Great Britain and France.
It is estimated that it was at the end of the last Ice Age (this whole area was frozen and the sea level was far much lower than today) that this territory began to separate from the continent, a process that ended in the Mesolithic period, in the middle of the Stone Age, becoming the insular territory we know today.
In fact, the current Irish Sea and the North Sea were dry land that was submerged with the rise of sea level in the thaw.

What is the capital of the united states largest state
Answer:
Juneau
Explanation:
The largest state in the United States is Alaska. The capital of this detached state is Juneau. Juneau has been the capital of Alaska since the beginning of the 20th century, more specifically from 1906. This city is actually not the biggest in Alaska, but instead it is the second largest, though it is a center of large portion of the things that happen in the state. The population of the city itself is little over 32,000 people, making it the least populous capital city of any state in the United States. As a metropolitan area though, the population is around 100,000 people. It can not really be expected for this city to be much larger as the climate and the geography simply don't provide the conditions for big growth.

Which two factors cause the perpendicular rays of the sun to move between 23.5o n and 23.5o s?
Answer:
It is the tilt of Earth's axis and Earth's rotation.
Explanation:
Both tilt and rotation are required for the perpendicular rays to move.
Final answer:
The movement of the sun's perpendicular rays between 23.5° N and S is caused by the Earth's axial tilt of 23.5 degrees and its elliptical orbit as per Kepler's Second Law, leading to the seasonal variations experienced on Earth.
Explanation:
The two factors that cause the perpendicular rays of the sun to move between 23.5° N and 23.5° S are the Earth's axial tilt and its elliptical orbit around the sun, which are also the basis of the seasonal changes we experience. The axial tilt of 23.5 degrees means that different parts of the Earth are closer or farther from the sun at different times of the year, leading to the Tropic of Cancer (23.5° N) and the Tropic of Capricorn (23.5° S) experiencing the sun's rays perpendicularly at the summer and winter solstices, respectively. Furthermore, the Second Law of Kepler, which states that a planet moves about the sun at such rates that the line connecting the centers sweeps over equal areas in equal times, contributes to the slight variations in the speed of Earth's orbit, affecting the exact positioning of the sun's perpendicular rays throughout the year.
