Magma. Water. Ice. Wind.
Water can breakdown rocks mechanically through a process called hydraulic action, where water enters cracks and crevices in rocks. When this water freezes and expands, it exerts pressure on the rock, causing it to crack. Additionally, water can carry sediment and debris that effectively wear down rock surfaces through abrasion.
Mechanically
The process of wearing away rocks by natural processes is called erosion. This can occur through various factors such as wind, water, ice, and chemical reactions. Erosion can result in the gradual breakdown and transport of rock particles to different locations.
Sandstone.
The chemical breakdown of enormous quantities of organic material buried in the sedimentary rocks has produced ethane gas.
Natural acids chemically weather rocks by reacting with minerals in the rock, causing them to break down. Mechanical weathering involves physical processes like freezing and thawing, which cause rocks to break apart without altering their chemical composition.
Sedimentary rocks can be both chemically and mechanically weathered.
The breakdown of rocks results in the formation of soil over many thousands of years.
The three factors that affect weathering are mechanical weathering (physical breakdown of rocks), chemical weathering (chemical changes in rocks), and biological weathering (weathering caused by living organisms).
