Biological weathering can occur from both mechanical force and chemical reactions. Add your answer and earn points. Over time, movements of the Earth and environment can break apart rock formations, causing physical weathering. There are three types of weathering. 4.12.3.5 Biological weathering. Examples of biological weathering 2 See answers xyz12384 is waiting for your help. Here are some examples of biological weathering. ... water, and biological organisms—has left behind an array of outstanding geological features, … Examples of Physical Weathering Physical weathering is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition. For example: tree roots can grow into fractures in a rock and pry the rock apart, causing mechanical fracturing. Chemical weathering is the breakdown of rock by chemical forces. Biological weathering only refers to weathering caused by organisms; animals, plants, fungi, and microorganisms such as bacteria. Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes.. weathering caused by the breaking down of rocks by physical force without any change in the chemical nature of the rocks. Water seeps into cracks in rocks, freezes, and expands, causing further breakdown of rocks. For example, plants, bacteria, fungi, burrowing animals, human beings and any part of the taxonomy of life. All of these processes break rocks into smaller pieces without changing the physical composition of the rock. It is due to the action of climate, plants, animals and other living organisms which cause the rocks to break down physically, chemically and biologically. Nnusaini9090 Nnusaini9090 Answer: One type, biological weathering , is caused by animals and plants. 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. They are physical weathering, chemical weathering and biological weathering. Weathering is the process of disintegration and decomposition of rocks. Mechanical weathering is usually caused by extreme hot and cold temperatures. 3. Biological weathering is an umbrella term for a complex group of processes that include the actions of a wide range of organisms. For example, rabbits and other burrowing animals can burrow into a crack in a rock, making it bigger and splitting the rock. Biological weathering isn't really a process, but living organisms can cause both mechanical and chemical weathering to occur. Heat and water are the most common agents of physical weathering. Physical weathering is the breakdown of rock by physical forces. Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. But the key factor is that it involves any type of living organism in nature. Wind is another example of mechanical weathering. Awesome examples of weathering and erosion over millennia. Biological Weathering: Many organisms play important roles in the weathering of rocks through physical and chemical means important organisms concerned with the decomposition of rocks are lichens, bacteria, fungi, higher plants, nematodes and other soil microbes. Oxidation, hydrolysis, and dissolution are the most common types of chemical weathering. Biological weathering can work in hand with […] Moss and fungus can also grow onto a rock.
