Whether fluctuating rapidly or slowly, environmental forces are always . a. static b. weak c. controversial d. dynamic

Option (D)

Explanation:

Environment refers to all the living and non-living components that surround us. There occur various processes such as precipitation, evaporation, weathering and erosion, deposition, and the processes that are associated with the various cycles such as geochemical cycle, nitrogen cycle, carbon cycle, phosphorous cycle and so on.

These processes occur in all the regions on earth and at different rates, and they are comprised of energy that is constantly in the flow from one region to another. These environmental changes and the forces that are involved in it are dynamic in nature.

Thus, the correct answer is option (D).

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
