- Mineral Composition. One type of weathering, known as chemical weathering, works at different rates depending on the chemical composition of affected rocks. ...

What are 3 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 are the 3 factors that affect the rate of chemical 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 factors that affects 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 weathering?
- rock strength/hardness.
- mineral and chemical composition.
- colour.
- rock texture.
- rock structure.
What are the 6 causes of 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.
What is the 2 types of weathering?
Weathering is often divided into the processes of mechanical weathering and chemical weathering . Biological weathering, in which living or once-living organisms contribute to weathering, can be a part of both processes. Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble.
What is the biggest cause of weathering and erosion?
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 5 main causes of physical weathering?
Pressure, warm temperatures, water, and ice are common causes of physical weathering.
What are 3 types of physical weathering?
- Abrasion: Abrasion is the process by which clasts are broken through direct collisions with other clasts. ...

What are the two most important factors that determine 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 factors affect the rate of erosion?
Major factors that affect the amount of erosion are soil cloddiness, surface roughness, wind speed, soil moisture, field size, and vegetative cover . A discussion of each follows. The cloddiness of a given soil largely indicates whether the wind will erode it.
What is the difference between weathering and erosion?
What is the difference between weathering and erosion? Weathering is the process of decomposing, breaking up, or changing the color of rocks. ... So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away , it is called erosion.
What are the five major factors that affect reaction rate?
Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances , the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the ...
How does water cause erosion?
Water flowing over Earth’s surface or underground causes erosion and deposition. Water flowing over a steeper slope moves faster and causes more erosion. How water transports particles depends on their size. When water slows down, it starts depositing sediment.
