Mechanical weathering
the atmostphere
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.

eartsh landforms are constantly changing.rocks in earths crust are slowly being broken into smaller pieces in a process called weathering.water,ice,temperature changes,chemicals,and living things cause weathering.there are two types of weathering,physical weathering and chemical weathering.
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
Plant roots cause Biological weathering which is indeed Mechanical in its nature. Animals burrowing is also a cause of Biological weathering.
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
Animal secrete acids and burrow into rocks and soil for shelter. Secreting acids cause chemical weathering. Animals burrowing causes mechanical weathering.
One cause of biological weathering is through the organism lichens. Other types are caused by plants, animals, and exposure to acids.
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
