Question

PLEASE!!! I NEED THIS ANSWERED ASAP!!!!!!!!! IM BEGGING YOU.
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.
6. As the waves recede, they carry the sediment away. In this scenario, which process represents weathering, and which process represents erosion?

Answer 1

Answer:

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.

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

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. 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.

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.

Explanation:

all of those are the correct answers

Answer 2

All questions deal with the impact of earth's endogenetic and exogenetic factors. Which include mass wasting, physical, chemical and biological erosion.

• The difference between the weathering and erosion is that erosion means to erode by the agents like air, water, ice, waves and man.  While weathering is the action of physical or mechanical, chemical, and biological breakdown or weathering down of the earth geomaterials.

• The mechanical and physical weathering are the same, that is block integration, onion peeling, etc. while chemical weathering includes oxidation, chelation, hydrolysis, carbonization, etc.

• Oxidation is the process of addition of O2 molecules to the minerals of rocks. Hydrolysis is the chemical break down of a substance by water.  

• Exfoliation  is the process of removal of upper layers of the rocks in the form of sheets. Caused by the cracking and peeling of the outer layer by thawing during the day and freezing during the night.

• The waves brings with them sediments and other deposits such as sand, mud, silt etc and these get deposited at the shore. As these are eroded particles that are broken off by the wave and wind action.

• When the waves receded they take with them fine and loose particles. The waves lead to erosion. This process is also the cause of beach formation.
