Answer:
1.Mechanical weathering is strictly a physical process and does not change the composition of the rock.
Common agents of mechanical weathering are ice, plants and animals, gravity, running water, and wind.
Physical changes within the rock itself affect mechanical weathering.
2.There are different types of chemical weathering processes, such as solution, hydration, hydrolysis, carbonation, oxidation, reduction, and chelation. Some of these reactions occur more easily when the water is slightly acidic.
3.Physical and Chemical Weathering both also have similarities too. Here are a few of them. They both made rocks and other sediments have cracks in them. Physical and Chemical Weathering made sediments into soil.
4.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.
