Question

1. What is the difference between weathering and erosion?

2. How are mechanical weathering and chemical weathering different?
3. How are hydrolysis and oxidation similar?
4. Explain the process of exfoliation
5. 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?

Answer 1

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.

Step-by-step explanation:

Answer 2

(1).When the smaller rock pieces are moved by these natural forces, it is called erosion. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.

(2).Mechanical weathering breaks rocks into smaller pieces without changing their composition. ... Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.

(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. Exfoliation is the cracking of rock caused by a decrease in pressure.

(4)Exfoliation is a process in which large flat or curved sheets of rock fracture and are detached from the outcrop due to pressure release: As erosion removes the overburden from a rock that formed at high pressure deep in the Earth´s crust, it allows the rock to expand, thus resulting in cracks and fractures along sheet ...

(5) The waves crashing into rock along the shorelines , particles of sand,shell. and other materials is the processs of of Erosion . THe last one where waves recede is Weathering .
