Which college classes would a student most likely take to become an oceanographer? select 4 choices.

I do not see the four choices, but here are the likelihoods; biology, chemistry, geology, and physics.

This is because there are four main components of study when it comes to becoming an oceanographer:

biological – studying marine plants and animals

physical – exploring water temperature, density, wave motion, tides and currents

geological – examining the structure and make-up of the ocean floor

chemical – analysing the chemicals in sea water and the impact of pollutants

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
