Rates of Weathering

that causes the increased rate of weathering of limestone. The material found in sediment grains also affects the rate of weathering. The mechanical weathering of rocks like shale and sandstone causes their grains to break up over time and become sand and clay particles. Why?

Soils - Soil Forming Factors: Parent Material, Climate and ...

Soils developed on parent material that is coarse grained and composed of minerals resistant to weathering are likely to exhibit coarse grain texture. Fine grain soil develop where the parent material is composed of unstable minerals that readily weather. Parent material composition has a direct impact on soil chemistry and fertility.

Weathering and Soils: Weathering - content.dodea.edu

The composition and structure of rocks also affect weathering rates. Limestone is particularly prone to weathering by carbonation, and silicate minerals are easily weathered by hydrolysis. Some rocks are just naturally more or less resistant to weathering than others.

Weathering - Wikipedia

Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.Weathering occurs in situ (on site), that is, in the same place, with little or no movement, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice ...

How does chemical weathering cause caves to form in ...

Limestone caves. Caves form in limestone (calcium carbonate), and occasionally in dolomite (calcium magnesium carbonate), when water containing dissolved carbon dioxide (carbonic acid) seeps into rock crevices and joints. This leads to further enlarging and sculpturing of the caves by chemical and physical weathering.
