What 3 things 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 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 properties affect weathering rates?
CLIMATE: The amount of water in the air and the temperature of an area are both part of an area's climate. Moisture speeds up chemical weathering. Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates.
What are the factors that influence the rate of weathering and erosion?
Rainfall, heat and moisture are the 3 main factors which affect the rate of weathering and soil erosion. Weathering happens more quickly in hot and wet climates. Wind is another major factor affecting soil erosion.
What factors affect weathering?
There are two factors that play in weathering, viz. Temperature and Precipitation. Warm climates affect by chemical weathering while cold climates affect by physical weathering (particularly by frost action). In either case the weathering is more pronounced with more moisture content.
What factors affect the rate of weathering quizlet?
What are two factors that affect the rate of weathering? The most important factors that determine the rate at which weathering occurs are the type of rock and the climate.
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.
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.
Which of the following are factors that affect weathering?
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.
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 factors cause weathering?
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.
Does weathering affect different materials differently?
Different minerals and rocks weather at different rates under the same conditions. Different temperature and precipitation will cause the same materials to weather differently. Vegetation increases weathering, both mechanical and chemical.
How does weathering affect different rock types?
Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.
What are the factors that affect weathering?
Factors affecting weathering
- Mineral composition.
- Grain (Particle) size.
- Presence of lines of weakness.
- Climate.
