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.
What else can I help you with?
When any type of rock undergoes weathering it usually forms this type of rock?
When any type of rock undergoes weathering, it usually forms sedimentary rock. Weathering breaks down existing rocks into smaller pieces that get deposited and compressed to form sedimentary rocks over time.
What is the type of weathering when ice forms cracks in rocks?
Ice wedging is a form of mechanical weathering.
What are the two main types of weathering?
The two main types of weathering are mechanical weathering and chemical weathering. Mechanical weathering involves physically breaking down rocks into smaller pieces, while chemical weathering involves the alteration of rock composition through chemical reactions.
What are the two kinds of weathering?
The two kinds of weathering are mechanical weathering, which breaks down rocks into smaller pieces without changing their chemical composition, and chemical weathering, which alters the chemical composition of rocks through processes like oxidation or dissolution.
Sentence for weathering?
Weathering is the process of breaking down and wearing away rocks, minerals, and soil through exposure to the elements such as wind, water, and temperature changes.
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 are forms of weathering?
Wind and rain
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 Asteroidal weathering?
The weathering of asteroids. Fe2SiO4 + hn > Fe + FeSiO3 + O Forms a metallic crust.
How do soil forms?
Soil form by weathering of rocks...:)
What Are two kind of weathering?
The 2 kinds of weathering are the Mechanical or Physical Weathering and the Mechanical Weathering.
What is the different forms of weathering called?
acid rain is one.
When the rock above a cave collapses forms a what?
It is called weathering.
When any type of rock undergoes weathering it usually forms this type of rock?
When any type of rock undergoes weathering, it usually forms sedimentary rock. Weathering breaks down existing rocks into smaller pieces that get deposited and compressed to form sedimentary rocks over time.
WHAT ROLE DOES WEATHERING PLAY IN THE FORMATION OF WEATHERING?
weathering occurs faster in warm and rainy climate. the rate of which soil forms depends on the climate and type of rock. so soil formation is faster when weathering is quicker too.
