What are the types of chemical weathering quizlet?

What type of weathering is chemical?

Chemical weathering is when chemicals in rain and moving water react with rocks and minerals to change or weaken them in some way. Chemical weathering always causes some type of chemical reaction within the rock or mineral itself. Expand your knowledge of the breaking down of rocks and soil through examples of erosion.

What are the two types of weathering quizlet?

The two types of weathering are mechanical weathering, which involves the physical breakdown of rocks without a change in chemical composition, and chemical weathering, which breaks down rock components and alters mineral constituents.

What are the 3 types of weathering?

There are three types of weathering, physical, chemical and biological.

What are the four processes of chemical weathering?

Chemical Weathering

Major chemical reactions include carbonation, dissolution, hydration, hydrolysis, and oxidation-reduction reaction. All of these reactions have water involved with them.

What are the three ways chemical weathering occurs?

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 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.
