Dandelions have seeds that are attached to tufts of material that resemble feathers. these tufts allow the wind to pick up and carry the seeds long distances. this is an adaptation

a) allows the dandelion to grow larger.

b) prevents predators from eating the seeds.

c) makes sure that no seeds grow very far from the parent plant.

d) allows the seeds of dandelions to travel long distances before taking root.

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
