NOT BIOLOGY! EARTH SCIENCE WASN'T A CHOICE!!

Deforestation - The clearing or cutting down of trees.

Desertification - The process by which habitable land turns uninhabitable.

Urbanization- The movement of people from rural areas to cities.

Explanation:

I had earth sciences last year and I forgot most of what happened but eh you could probably solve this with the root words of the words.

"Deforest," or "derive of a forest." Cut down trees.

"Desert" or "deserted," uninhabitable.

"Urban, urbanized" like "urbanized area" or "urbanized population" which relates to a town or a city.

Hope this helped.
