Weathering is primarily caused by three main forces: mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering occurs when rocks are broken down into smaller pieces through physical processes such as freezing and thawing. Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation and hydrolysis. Biological weathering is caused by living organisms, which can break down rocks by their growth, burrowing, or through chemical processes.
Three weathering forces that help change rocks into soil are physical weathering, chemical weathering, and biological weathering. Physical weathering involves the breaking down of rocks into smaller pieces through processes like freezing and thawing. Chemical weathering involves the chemical alteration of minerals within rocks, while biological weathering involves the action of plants, animals, and microorganisms breaking down rocks.
The forces of mechanical weathering include frost wedging (freeze-thaw cycles), root wedging (roots growing into cracks), abrasion (rock-on-rock friction), and pressure release (rock expansion due to removal of overlying material). These forces break down rocks into smaller fragments over time.
Three causes of weathering of the lithosphere are physical weathering, which includes processes like frost action and plant roots breaking up rocks; chemical weathering, which involves chemical reactions that weaken or dissolve rocks; and biological weathering, where organisms like lichens and bacteria contribute to rock breakdown.
The steepness of the river's slope, the volume of water flowing in the river, and the type of rock or sediment being eroded are the three main factors that affect how much energy a river has to cause weathering, erosion, and deposition. The faster the flow, the more erosive the river can be.

Three types of weathing
There are three things that cause weathering in rocks. These factors are wind, plants, and water. Wind and water make the rock dissolve away. Plants can cause the rocks to crack.

A fossil could be destroyed by heat due to melting, pressure from colliding bodies of rock, or from weathering at the surface.

ice,water,and weathering
Internal forces: tectonic plate movement, volcanic activity, and earthquakes. External forces: weathering, erosion by water/wind/ice, and impact events (e.g. meteorites).
Three forces that cause erosion are wind, water, and ice. Wind erosion occurs when wind carries sediment and wears away rocks. Water erosion happens through the force of flowing water which can transport sediment and carve out channels. Ice erosion, known as glacial erosion, occurs when glaciers move and scrape against the Earth's surface, picking up and carrying sediment.
