Which weathering process involves the constant freezing and thawing of water?

True

Explanation:

If we eat an hour before the exercise then our body gets enough energy to carry out the physical activities. Extending more than two hours of a meal before the exercise is not advisable.

Consuming carbohydrate and protein rich food after the exercise is a must as it stimulates the synthesis of muscle protein. Working out in an empty stomach or after a light meal is not suggested as the body burns more fat during the exercise even when enough food is not consumed.

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
