What are the causes of mechanical and chemical weathering?
Freezing and Thawing, Release of pressure. Growth of plants, actions of animals & Abrasion.
Classify freezing or thawing oxidation water dissolving chemicals in rock abrasion acid rain?
Freezing or thawing are classified as mechanical weathering. Water dissolving and oxidation of chemicals in rock acid rain are classified as chemical weathering.
Which one of the following is a source of chemical weathering a The abrasion of running water b water freezing in the cracks of exposed rocks c the effects of acid from decaying animals d the growth?
C. The effects of acid from decaying animals
Compare and contrast chemical weathering and mechanical weathering?
Mechanical weathering is taking a big rock and breaking it down to small rocks by releasing pressure, freezing and thawing (water and ice), animal action, plant growth and abrasion. Chemical weathering is when a rock loses it shape but STILL IS MADE OF THE SAME METRICAL. Chemical weathering uses water, oxygen, carbon dioxide, living organism, and acid rain.
What are the effects of mechanical weathering?
Freezing And Thawing, Release of Preserve,Actions of Animals,plant growth,abrasion
What is weathering due to repeated freezing and melting of water called?
chemical weathering
Is freezing and thawing classified as chemical weathering or mechanical weathering?
It is considered mechanical weathering because it is physical.
Explain the difference between mechanical and chemical weathering?
In chemical weathering, there is a chemical reaction that causes weathering. Mechanical weathering is caused by fire, abrasions of water along a surface, animals, or freezing and thawing.
How are rocks weatherd?
When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.
Mechanical Weathering?
In mechanical weathering, rocks are broken down into smaller pieces without changing their composition. Mechanical weathering is caused by freezing and thawing, release of pressure, plant growth, action of animals, and abrasion.
Is freezing and thawing chemical weathering or mechanical?
Freeze/thaw cycles are an example of mechanical weathering of rock.
Is water freezing in the cracks of exposed rocks a source chemical weathering?
No. Chemical weathering is only when acid rain etc. is involved. I suppose you could call this 'natural weathering' but I'm not sure that is the correct term because it is simply water freezing and expanding.
