Give Reason. The Vegetation becomes dense where the rainfall is heavier.
Answers
Vegetation is dense in the areas that have heavy rainfall because rainfall makes the land more fertile and supplies an adequate amount of water needed for cultivating.
Areas with moderate to high temperature and abundant rainfall throughout the year are highly forested. Areas with somewhat less rainfall are mainly grasslands.Even in the areas with high yearly rainfall, trees are limited if there is no much rainfall during the warm growing season.
Regions with not much rainfall and scarce vegetation are deserts. Areas with somewhat greater rainfall are called semiarid regions. The problem with semiarid regions is that when human use them for agriculture, the loss of natural vegetation can cause the areas to become deserts.
