Name the membranous encasement surrounding the brain.

Meninges

Explanation:

Meninges refer to the protective membranes that surround the brain. Dura mater is the outer most meninx which forms a tough and fibrous cover. Pia mater is the deepest meninx and represent the delicate layer of connective tissue. Present between pia mater and dura mater is the arachnoid mater. Together, dura mater, arachnoid mater and pia mater make a membranous encasement to cover the brain and protect it from any injury.

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
