Explain how weathering is occurring in A, B, and C.
Answers
Answer:
Weathering happens through processes or sources in the environment, including events like wind and objects like the roots of plants. Weathering is either mechanical, in which rocks are broken down through an external force, or chemical, which means rocks are broken down through a chemical reaction and change.
Explanation:
There are three types of weathering, physical, chemical and biological.
Biological Weathering vs. Physical and Chemical Weathering
The three different types of weathering are physical, chemical and biological. Physical weathering is caused by mechanical forces, without any change to the makeup of the rock. For example, water can freeze inside small holes in rock, causing the rock to split and crack. Chemical weathering is caused by reactions among minerals in the rock and outside chemicals. Perhaps the best-known type of chemical weathering is acid rain, precipitation that contains acids that corrode the surface of rock.
Biological weathering only refers to weathering caused by organisms -- animals, plants, fungi and microorganisms such as bacteria. While certain forms of biological weathering, such as the breaking of rock by tree roots, are sometimes categorized as either physical or chemical, biological weathering can be either physical or chemical. Biological weathering can work hand in hand with physical weathering by weakening rock or exposing it to the forces of physical or chemical weathering.
