Oceanography but the study of ocean creatures is Marine Biology
I think the correct answer is weathering. It is this process where rocks are break into tiny fragments by air, water and ice. It breaks down or loosens surface so they are transported away. Hope this answers the question. Have a nice day.
Isostatic adjustment usually occur when there is a void to attain a stable equilibrium hence when the void is filled due to the isostatic adjustment hence soil erosion occur
I'm not 100% sure but I think the answer you are looking for is something like for example; Forest, grassland, tundra, desert, & maybe Ice sheets.
all of the above d because all can be from animals
