The factors that affect the rate of weathering are humidity, the composition of rocks, high temperatures, vegetation and wind. In a hot and wet environment, weathering tends to be rapid. In dry climates, weathering is slower.Continue Reading
Sedimentary rocks are soft and break down quickly. Metamorphic rocks, such as slate and marble, tend to weather slowly. Granite and basalt rocks are hard and take longer to degrade when exposed to the agents of weathering.
Rainfall affects weathering as running water tends to break down rocks quickly. When the land is covered by vegetation, it does not weather quickly. Rocks exposed directly to heat, wind and water tend to weather very quickly.Learn more about Erosion & Weathering
Physical weathering, also called mechanical weathering, refers to the process of breaking rocks apart while retaining their chemical composition, according to the American Geosciences Institute. It means that rocks slowly wear away due to physical changes, such as temperature changes, freezing and thawing, wind, rain and waves, explains the BBC.Full Answer >
Erosion changes the Earth's surface by a process of breaking down and displacing soil and other material caused by wind, rain and other types of weathering. Erosion may cause soil in a region to be loosened, transported and deposited in a new area.Full Answer >
In physical or mechanical weathering, abrasion occurs when moving particle sediments abrade the surface of exposed rocks. As these particles rub against exposed rocks, it leads to wearing away of the rocks through friction. The particle sediments, such as smaller rocks, are carried through media that includes water, ice and wind.Full Answer >
The process in nature that breaks down rocks is called physical weathering. Physical forces such as abrasion, frost action, salt crystal growth, thawing, freezing and temperature fluctuation weaken rocks and cause them to crack and disintegrate over time. Fluctuations in temperature over time can cause rocks to break as a result of constant stress from contraction and expansion.Full Answer >
