What are the two main factors that determine 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.

What are the two main types of weathering?

Weathering is often divided into the processes of mechanical weathering and chemical weathering.

What are the 3 factors that influence 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 two most important factors in chemical weathering?

Water is the most important agent of chemical weathering. Two other important agents of chemical weathering are carbon dioxide and oxygen.

What are the 2 types of weathering and how are they different?

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. … Exfoliation is a form of mechanical weathering in which curved plates of rock are stripped from rock below.

What factors cause 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).

How do you identify chemical weathering?

By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water.

What are the main types of chemical weathering?

There are five types of chemical weathering: carbonation, hydrolysis, oxidation, acidification, and lichens (living organisms).

What are four factors that affect how fast weathering happens?

Some features of climate that affect weathering are temperature, mois- ture, elevation, and slope. Temperature is a major factor in both chemical and mechanical weathering.

What are the two basic categories of weathering how do the products of each category of weathering differ?

How do the products of the two categories of weathering differ from each other? Mechanical weathering results in broken pieces that are of the same composition as the original material, whereas chemical weathering alters the composition of the material.

What are the two forces of nature that contributes mostly in the weathering of rocks?

Heat, cold, water, and ice all contribute to weathering. So do the oxygen and carbon dioxide in the atmosphere. Repeated freezing and thawing, for example, can crack rock apart into smaller pieces. Rainwater can dissolve minerals that bind rock together.

What are 2 examples of physical weathering?

These examples illustrate physical weathering:

  • Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. …
  • Ice wedging. Ice wedging causes many rocks to break. …
  • Plant roots. Plant roots can grow in cracks.
