What gives wind its mass? a) barometric pressure
b) air molecules
c) air pressure
d) the convection cell

air pressure

Explanation:

Air masses tend to flow from areas of high air pressure to areas of low air pressure. Thus, winds blow away from high-pressure areas; wind blows towards low-pressure areas. Air masses also move vertically.

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
