The part of the ear that can be seen is also called

Pinna

The pinna is the main obvious piece of the ear (the auricle) with its exceptional helical shape. It is the initial segment of the ear that responds with sound. The capacity of the pinna is to go about as a sort of channel which helps with coordinating the sound further into the ear. is the main obvious piece of the ear (the auricle) with its exceptional helical shape.

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
