As waves crash into rock along the shoreline, particles of sand, shell, and other materials in the ocean water loosen tiny bits of sediment from the rock. As the waves recede, they carry the sediment away. In this scenario, which process represents weathering, and which process represents erosion?

1.Weathering is the breakdown of rock into smaller particles through mechanical or chemical means. Erosion is the process by which weathering products are carried away.

2.Mechanical weathering simply breaks rock into smaller fragments. Chemical weathering actually changes the mineral composition of rock.

3.Hydrolysis and oxidation are similar in that both involve chemical reactions between a mineral and another material. Hydrolysis is a chemical reaction between a mineral and water. Oxidation is a chemical reaction between a mineral and oxygen.

4.Exfoliation is the cracking of rock caused by a decrease in pressure. It occurs when a mass of rock is exposed by weathering and removal of the overlying rock, which decreases pressure on the rock. As a result, the rock expands, which causes the rock to crack.

5.In the scenario, weathering occurs when tiny bits of sand and shell in the waves loosen bits of sediment from the rock. Erosion occurs when the waves carry away those bits of sediment.
