How does Glaciation affects the soil? (Both in a good way and a bad way) Thanks!

Answers

Glaciers carry soil from one place to another. This means that a lot of the fertile soil used mainly for that one area could have been taken away and effected negatively because the fertile soil on the bottom isn't as good as the one on the top, which has been dragged away by glaciers. However, it can take soil to environments where soil is needed, helping it.

What is carbon?

The chemical element carbon has the atomic number six and the letter C assigned to it. It has a tetravalent atom, which means that four of its electrons can be used to create covalent chemical bonds. It is nonmetallic. The periodic table's group 14 includes it. The crust of the Earth contains 0.025 percent carbon.

Similar to hydrogen, oxygen, lead, and all the other chemical elements listed in the periodic table, carbon is an element. An extremely common element is carbon. As in diamonds and graphite, it can exist in pure or almost pure forms, but it can also interact with other elements to form molecules.

The half-life of carbon-14's degradation into nitrogen-14 is 5730 years, making it an unstable element. The time it takes for half of the Carbon-14 atoms to decay back into Nitrogen-14 is therefore 5730 years.

Therefore, Thus option (c) is correct.
