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.Know More
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.
Weathering creates underground caves and passages in limestone in addition to depressions and other unusual dips and grooves on the surface. Karst is landscape formed from the weathering of limestone.Full Answer >
Weathering refers to the process of wearing away, dissolving or breaking down rocks that are found near or at the surface of the Earth. National Geographic notes three types of weathering processes: mechanical, chemical and biological or organic.Full Answer >
Mechanical weathering is the erosion of rock caused by physical processes. Extreme temperature changes and constant exposure to water or air are common causes of mechanical weathering.Full Answer >
The primary difference between weathering and erosion is that weathering refers to the erosion of natural substances without movement, while erosion includes movement of particles and surface materials. Weathering and erosion take place in the same locations and affect the same landforms, but erosion involves the movement of loosened particles and surface materials downwards via the force of gravity. Particles, such as small pieces of rock, sand and dirt dislodge during erosion, which requires a triggering force, typically wind, rain or ice.Full Answer >
