How does vegetation affect climate?

Answer 1

Vegetation affects the climate primarily through transpiration. If the area contains a large number of trees and vegetation, it has the most amount of precipitation as rain. For e.g the Amazon rain forest has extremely dense vegetation. Because of this it rains almost everyday. And places which can support vegetation but don't have any are likely to become deserts if they are not preserved quickly enough. And places with dense vegetation are more cooler in summer but are extremely humid

Answer 2

Because the nutrients in the ground are soaked up by the trees and other plants. That then starts the nutrient cycle. The nutrient cycle is that the nutrients from the vegetation in the ground are soaked up by the trees which then makes the leaves fall off the tree carrying the nutrients with it. The nutrients are the buried in the ground and the nutrient cycle is back at the begining.
