Which scenario is an example of a negative feedback loop? \ a)when body temperature increases, sweat is produced as a cooling agent to lower body temperature. b)in some parts of the world, birth rates are far exceeding death rates, which has led to overpopulation. c)ice reflects sunlight much better than water. a warmer atmosphere is turning ice to water, which is absorbing more of the sun’s energy. d)a warmer atmosphere is leading to warmer oceans. a warm ocean releases more carbon dioxide, which traps more heat in earth’s atmosphere.

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
