Mechanical weathering

air oxidation, groundwater, and acid precipitation
Thats Very False!! NOT TRUE!
In chemical weathering mosses and linches have been found to grow on rocks and release chemicals that dissolve minerals from rocks. roots from plants are able to invade cracks with in rocks and increase the size of the cracks. There are a number of trees and other plants that release acidic chemicals which can cause weathering of the rocks, minerals, and soil around them. Plants also can have an affect on the way water weathers rocks and soils, they can channel water in specific directions that cause greater weathering or they can lessen the impact of rain falling on the ground. They also affect wind speed and direction near the surface of the ground having an effect on weathering in arid regions of the world.

Water is a major component in weathering process. Its essential for all forms of disintegration either Mechanical/Physical, Biological or Chemical. Water aids in physical weathering through alternating wetting and drying of rocks thereby leading to breaking down of the rock. It helps in chemical weathering through dissolution of chemicals in rocks such as limestone. Water is a cause of both chemical and physical weathering.
The type of weathering caused by the actions of animals is known as biological weathering. Animals contribute to this process by burrowing, digging, and moving materials on the earth's surface, which can break down rocks and contribute to their erosion over time. This type of weathering is particularly common in areas where animal activity is high, such as in burrowing animals or organisms that live in the soil.
factors that cause weathering are erosion and water
Weathering may occur through the actions of water, air, plants, animals and various chemicals. Mechanical weathering is the breaking down of rocks into smaller pieces without changing the composition of the minerals in the rock
When animals walk across them it can cause weathering.
Animals cause mechanical weathering in various ways. One of the common ways is by stepping on rocks with their hooves and breaking them down.

animals are effected because the cause of weathering destroys the animals habitat.
Weathering of any kind can sometimes cause problems, like erosion of topsoil. Biological weathering, where the weathering is caused by living things (plants and animals), can cause the same kinds of problems.
Burrowing, walking, defecation, urination.
Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion
Weathering processes such as mechanical (physical) weathering, chemical weathering, and biological weathering can cause rocks to break apart into smaller pieces or sediment. Mechanical weathering includes processes like freeze-thaw cycles, abrasion, and root wedging. Chemical weathering involves reactions with water, oxygen, and acids that dissolve or weaken rock minerals. Biological weathering results from the actions of plants, animals, and microorganisms that break down rocks through physical or chemical means.
Animal secrete acids and burrow into rocks and soil for shelter. Secreting acids cause chemical weathering. Animals burrowing causes mechanical weathering.
