(a) Frost Action: Water on freezing undergoes an increase in its volume by about ten per cent. This expansion is accompanied by exertion of pressure at the rate of 140 kg/cm 2 (2000 lbs/in 2) on the walls of the vessel containing the freezing water.In areas of intensive cold and humid climates, temperatures often fall below the freezing point of water repeatedly during winter …

14 Weathering and Erosion

scrape against each other and against stationary rocks. Thus, exposed surfaces are weathered by abrasion. Wind is another agent of abrasion. When wind lifts and carries small particles, it can hurl them against surfaces, such as rock. As the airborne particles strike the rock, they wear away the surface in the same way that a sandblaster would.

Geology – Bluff Shelters of the Arkansas Ozarks

That is, rock strata or layers are bent, folded, and changed by the action of large sections of the Earth's crust pushing against each other. This creates wrinkles and bumps in the strata and lifts the entire region. The Ouachita Mountains in Arkansas are an example of that. You can see evidence of it in the way the rocks look folded and bent.

weathering | National Geographic Society

Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

Weathering Processes | Physical Geography

Weathering Processes. Weathering is the process that changes solid rock into sediments. With weathering, rock is disintegrated into smaller pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments away from it's original position. The four forces of erosion are water, wind, glaciers, and gravity.

Mechanical Weathering Through Physical Processes

Mechanical weathering is the set of weathering processes that break apart rocks into particles (sediment) through physical processes. The most common form of mechanical weathering is the freeze-thaw cycle. Water seeps into holes and cracks in rocks. The water freezes and expands, making the holes larger. Then more water seeps in and freezes.
