CAUSES OF GLOBAL CHANGE The diagram is a simplified model of four Earth systems-the atmosphere, hydrosphere, biosphere, and geosphere-and the changes that
their interactions cause

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

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

c. live where it’s cold and icy

the answer is c. it will give up it's valence electron to the other atom.
