wo important classifications of weathering processes exist - physical and chemical weathering. Mechanical or physical weatheringinvolves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure. The second classification, chemical weathering, involves the direct effect of atmospheric chemicals or biologically produced chemicals (also known as biological weathering) in the breakdown of rocks, soils and minerals.[1]
The materials left over after the rock breaks down combined with organic material creates soil. The mineral content of the soil is determined by the parent material, thus a soil derived from a single rock type can often be deficient in one or more minerals for good fertility, while a soil weathered from a mix of rock types (as in glacial, aeolian or alluvial sediments) often makes more fertile soil.

Sentence for weathering?
There are three main forms of weathering.
What kind of weathering happens when ice forms in cracks in a rock?
When ice forms in cracks in rocks, the kind of weathering is known as mechanical weathering. The type of mechanical weathering that freezes and thaws is frost wedging.
What forms as the results of weathering?
it depends on what you mean by that. Well, what forms as the result of weathering could be tornados, tsunamias, dust devils, etc.
What is the type of weathering when ice forms cracks in rocks?
Ice wedging is a form of mechanical weathering.
Is a cave weathering or erosion?
A cave is an agent of erosion. More specifically, chemical weathering forms caves.
What are two ways mechanical weathering change rocks?
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
What are two famous land forms that are made by weathering?
Mountains and Valleys.
What are two ways that mechanical weathering changes rocks?
Ice live

What does weathering cause?
weathering results in the disintegration of rocks on a large scale. then these rocks break-up and forms soil and the soil forms the soil profile.
What is the type of weathering when ice forms cracks in rocks?
Ice wedging is a form of mechanical weathering.
Is a cave weathering or erosion?
A cave is an agent of erosion. More specifically, chemical weathering forms caves.
What is Asteroidal weathering?
The weathering of asteroids. Fe2SiO4 + hn > Fe + FeSiO3 + O Forms a metallic crust.
