Answer:
Oxygen
Explanation:
The earth has been divided into three major categories crust, mantle, and core which are further segregated into sub-parts. Since the crust is the outermost layer of the shell, the outer crust of the earth consists of a combination of silicon and oxygen in the majority followed by some percentage of other metals as well. <u>The percentage of Oxygen includes nearly 50% i.e. 46.6% followed by 27.7% of Silicon and the other 25.3 % includes aluminum, iron, sodium, magnesium, etc</u>. Thus, '<u>oxygen</u>' is the correct answer.
Answer:
Africa is the region that has population growth based on a high total fertility rate.
Explanation:
On this graph, we can see that the predictions for the global population are that it will continue to grow. That is not to say that there will be proportional growth in all regions though, as there are differences from one region to another. There's one region that will have exponential growth, one that will have minor growth, two will stagnate, and one will actually experience a slight decline.
The only region that will have a big population growth is Africa. The reason for this is that this region is predicted to retain its very high total fertility rate. With the living conditions gradually improving over time, especially the healthcare system, this will lead to big decline in the mortality rate, which will even more pronounce the large fertility rate, so the population will rapidly grow.
Carbon dioxide. Forests act as huge sources for carbon dioxide.
hope that helps! :)
I am pretty sure that the answer is remote sensing.
Erosion is largely caused by Glaciers.
