Which of these factors influence the type and rate of weathering quizlet?
The most important factors that determine the rate of which weathering occurs are the type of rock and the climate.
What factors influence 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 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 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.

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.
How does surface area affect the rate of weathering?
Large rocks have less surface area for their volume than small rocks. Therefore a smaller portion of the rock is exposed to weathering. It takes longer for the rock to wear away. The small rock has more surface area for its vol- ume so it weathers away faster.
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 types of weathering?
There are three types of weathering, physical, chemical and biological.
What are 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.
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 influence the rate of weathering of Earth materials quizlet?
When the amount of surface area relative to volume increases, the rate of weathering increases. How does climate affect the rate of weathering? Some climates such as warm, humid climates will cause rocks to weather faster.
What are other types of weathering factors?
Weathering of rock is a complex process and depends on many factors including:
- Climate – wind, rain, frost & temperature.
- Topography (e.g. waterlogged valleys are subjected to deeper weathering than plateaus)
- Rock structure (e.g. presence of faults, joints etc dictate rock fracturing due to freeze-thaw cycles)
What is the most common type of weathering?
One of the most common types of physical weathering is wedging. Wedging occurs when a substance finds its way into cracks or holes in rock and expands outward.
What is weathering and what are the two types 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. Mechanical weathering is the disintegration of rock into smaller and smaller fragments.
What are the 4 types of weathering?
There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering.
What is the rate 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 factors control weathering rates?
Water and temperature are key factors controlling both weathering rates and the types of weathering that occur:
- Water is required for chemical weathering reactions to occur.
- Water must be present for ice wedging to happen.
- Higher temperatures speed up chemical reactions.
What is the types of weathering?
There are three types of weathering, physical, chemical and biological.
What makes the two types of weathering different from each other?
Processes that break down and weaken earth minerals are known as weathering. Over time, this can lead to erosion, in which huge sections of rock and stone are carried away, changing landscapes. Physical weathering alters the material structure of rocks, while chemical weathering alters their chemical structure.
Which of the following is a type of physical weathering?
Types of physical weathering include frost wedging, thermal expansion and contraction from heating and cooling, biological growth of organisms such as trees, abrasion, and exfoliation (unloading).
How does climate influence the weathering of rock quizlet?
How does climate influence the weathering of rock? Areas with high temperatures and abundant moisture will generally have the highest rates of chemical weathering.
What are the 3 types 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.
What are 5 types of weathering?
Types of Mechanical Weathering. There are five major types of mechanical weathering: thermal expansion, frost weathering, exfoliation, abrasion, and salt crystal growth.
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 has the most influence on the rate of weathering?
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
What are the types of weathering define each type?
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.
What are the different types of weathering describe each?
There are two types of weathering: mechanical and chemical. Mechanical weathering is the disintegration of rock into smaller and smaller fragments. Frost action is an effective form of mechanical weathering.
What is the type of weathering?
There are three types of weathering, physical, chemical and biological.
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.
