Not all areas on earth's surface receive the same amount of radiation because earth's surface a. is flat c. has continents on it b. is curved d. is mostly water select the best answer from the choices provided a b c d

The answer to your question is D

B. Is curved

Explanation:

Earth surface is curved, not flat. Due to the curved earth surface, some part of the earth surface gets direct and straight solar radiations than others.

For example, the regions located near equator get direct and straight solar radiations imparting them higher temperature. On the other hand, the regions near poles obtain slant solar radiations. This is the reason that polar regions have colder climatic conditions.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
