Why do deserts exist in different parts of the world?
Deserts exist in different parts of the world because the climate conditions in those parts of the world promote the formation of deserts. Desert locations cannot be attributed to the break up of Pangea. That is because a desert that existed on Pangea would have been in a different climatic location after the break up of Pangea. As the plates (land masses) moved over the course of earth’s history, the climate on those plates changed. Example: marine fossils found at the high elevations of the Himalayas.
