Biological weathering
hehehe
One cause of biological weathering is through the organism lichens. Other types are caused by plants, animals, and exposure to acids.
Gravity plays a small part in mechanical weathering but temperature, weather, animals, plants, water and wind play much bigger parts.
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.
Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion
weathering, there are four types of weathering, chemical weathering, caused by acid rain, onion skin weathering, caused by change in temperature eg in the dessert it's boiling at day and freezing at night, freeze-thaw weathering, caused by water freezing and melting, expnding a crack inside a rock, and biological weathering, caused by plants and animals (including humans) eg walking on stone steps again will eventually wear it.
Results from the actions of plants and animals.
There are two primary effects: chemical weathering by acidic secretions, decomposition by-products etc; and wedging of fractured rockby tree-roots. Animals may also create minor, purely local soil erosion, though the so-called "sheep tracks" (miniature terraces)on steep hillsides are formed by soil-creep, not trampling.
Ice wedging and, plants + animals
bwcause it is the formation of fossils
Biological weathering is caused by activities of living organisms, such as plants and animals. This includes processes like root growth, burrowing, and decay that break down rocks and minerals over time, contributing to the erosion of Earth's surface.
