I think it is erosion (2) because erosion removes soil, rock, and dissolved material.
a star expels most of its outer material until only the hot core remains, which then settles down to become a young a white dwarf
I mean there is a lot of evidence that evolution has happen but i think if someone were to say it was false they would be getting into a religious beliefs. So I would say if you are using evidence than no it cannot be proven false. Hope this helps(;
A population will most likely deplete the resources of its environment if the population "increases".
