What are two major weathering?
The two main types of weathering are physical and chemical weathering. This page describes mechanical (physical) weathering (and more). Rocks are naturally fractured at several levels. Mineral grains have boundaries, which can be areas of weakness in the rock.
What are the main types of weathering?
There are three types of weathering, physical, chemical and biological.
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 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 2 types of erosion?
There are two types of erosion: intrinsic and extrinsic.
What are the two types of weathering that transform rock into soil?
- Exfoliation: When temperature of rocks rapidly changes that can expand or crack rocks. …
- Freeze-thaw: When water freezes, it expands. …
- Abrasion: When the wind blows, it can pick up sand and silt, and literally sandblast rocks into pieces.
- Root Expansion: Like freeze thaw, roots grow bigger every year.
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.
