What are 4 factors that affect the rate of weathering?
Rocks that are fully exposed to the atmosphere and environmental elements, such as wind, water and temperature fluctuations, will weather more rapidly than those covered by ground. Another factor that affects the rate of weathering is the composition of rock.
What factors determine the rate of weathering quizlet?
The two factors that affect the rate of weathering are the rock's type and the climate. If a rock is permeable, it weathers easily. The mineral content of the rocks influence how fast it would weather. There are minerals which dissolve easily in particular substances.
What are the 5 factors that affect the rate of weathering?
Factors affecting weathering
- rock strength/hardness.
- mineral and chemical composition.
- colour.
- rock texture.
- rock structure.

What are the 7 factors of weathering?
What Factors Cause Mechanical Weathering?
- Exfoliation or Unloading. As upper rock portions erode underlying rocks expand. …
- Thermal Expansion. Repeated heating and cooling of some rock types can cause rocks to stress and break resulting in weathering and erosion. …
- Organic Activity. …
- Frost Wedging. …
- Crystal Growth.

What are the rates of weathering?
The weathering rate for rocks depends on the composition of the rock; the climate of the area; the topography of the land; and the activities of humans, animals, and plants. A rock's composition has a huge effect on its weathering rate. Rock that is softer and less weather-resistant tends to wear away quickly.
What are the three factors that affect the weathering rates?
Generally, interactions with air, water and living organisms cause the weathering of rocks. Although there are two major types of weathering processes, physical weathering and chemical weathering cannot be separated, and they often work together at different rates to break large rocks into smaller pieces over time.
How does climate affect the rate of weathering?
In general, hot wet climates accelerate chemical weathering while cold dry climates accelerate physical weathering. Although the rate of weathering depends on the type of rock, rocks in tropical climates experience the highest rates of weathering because of the combination of high heat and heavy rainfall.
What are two factors that cause differential weathering?
- control frequency of freeze thaw cylces.
- rate of chemical weathering.
- kind and amount of vegetation present.
How does temperature affect the rate of weathering?
Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.
What are 3 factors that affect weathering?
Factors that affect weathering are :
- Local climate.
- Mineral composition.
- Structure of rock.
- Human activities.
- Amount of exposed or bare rocks surface, and human activities.
What are the 3 main factors that affect chemical weathering?
The major reactions involved in chemical weathering are oxidation, hydrolysis, and carbonation. Oxidation is a reaction with oxygen to form an oxide, hydrolysis is reaction with water, and carbonation is a reaction with CO2 to form a carbonate.
What are the four main causes of weathering?
Weathering breaks down the Earth's surface into smaller pieces. Those pieces are moved in a process called erosion, and deposited somewhere else. Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature.
What causes the most weathering?
Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical.
What are the 3 types of weathering?
Weathering is the breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.
