Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.

Explanation:
The energy of the earth's interior is known as the earth's internal energy. This powers the internal processes within the earth.
- This energy is very important in the rock cycle for the formation of both igneous and metamorphic rock.
- The energy is a product of frictional heating, radioactive decay of isotopes and heat that acreted when the earth was forming.
- The internal engine is responsible for mantle convection in which molten rock from within the earth rises to the surface and denser slabs of the lithosphere falls back within.
- It is responsible for the heating of sedimentary rocks to form metamorphic rocks around subduction zones.
