One theory behind savanna formation is that wet forest species are unable to withstand the dry season, and thus savanna, rather than rain forest, is favored on the site.

Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.

Desert areas will be dry and baron, There will also be lush forest areas that will assuredly have rain almost constantly.
