Compact bone has columns of tissue called?

Haversian system or Osteon

Explanation:

The cylindrical shaped units present in compact bones are called Haversian systems. Also called as osteon, each Haversian system has a matrix in the form of thin layers. These thin layers of the matrix are called lamellae and are arranged in concentric layers called central canals. The space between the lamellae of each osteon is occupied by osteocytes.

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
