What is the difference between mechanical and chemical weathering is .?

∙ 6y ago
mechanical weathering is the breaking down of rocks without chemical change in the rocks. for example frost wedging is a type of mechanical weathering where water gets into cracks in rocks and then freezes and expands, breaking up the rock. chemical weathering changes the rock chemically. rust forming on iron is an example of chemical weathering.

∙ 12y agoMechanical (physical) weathering is the breakdown of rock into smaller particles due to such factors as freezing and thawing, release of pressure, water absorption, salt crystal formation, landmass uplift, expansion and contraction from the sun or fire, plant root growth, actions of animals, abrasion, or other means that do not directly affect the rock's chemistry.
Chemical weathering is the dissolution, carbonation, oxidation, or hydrolysis of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater. Other materials are formed in the process. Warm, tropical climates are ideal environments for chemical weathering to take place as the chemical reactions are quickened by the bountiful rain and warm temperatures.

What are the difference between mechanical weathering and chemical weathering?
The differences are that mechanical weathering breaks rocks into little pieces.. Chemical weathering not only breaks the rock but dissolves it.
What is the main difference between chemical and mechanical weathering?
SPELLING.
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.
What is the difference between chemical and mechanical weathering in deserts?
suck a dick ;)
What is one difference between chemical and mechanical weathering?
Chemical weathering is the breaking down of a rock on a minute level, like the solution of minerals. Mechanical weathering is the breaking down of a rock, sometimes causing a crack through an entire strata, resulting in mass movement; but mostly mechanical weathering is as a result of a factor which causes the rock to physically separate.
What is the principal difference between weathering and chemical weathering?
occures when the chemical comosition of the rock changes
What is the difference between physical and chemical weathering change?
chemical weathering change will most likely make a new substance
Explain the difference between chemical and physical weathering?
Chemical weathering is which makes new substances, whereas physical weathering is where rock is changed into smaller pieces of the same substance.
What are the differences between mechanical weathering and biological weathering?
biological weathering is when plants grow inside of a rock and break it apart, mechanical weathering is when rocks are broken apart by a force
What is different between physical weathering and chemical weathering?
Physical weathering is breaking down of rocks by weather that does not change their chemical components. Chemical weathering is weathering that breaks rocks down by a chemical change.
How are chemical weathering and mechanical weathering alike?
Mechanical weathering results from abrasion of a surface chipping away at the surface and removing small pieces. Chemical weather results from chemical reactions occurring between the material of the surface and the surrounding environment. In both cases small amounts of material may be removed gradually through the weathering process. Because a surface may not be homogeneous, some parts will be more resistant to mechanical weathering than others, resulting in pitting where the material is weaker. Likewise, a heterogeneous surface will exhibit pitting from chemical weathering as the environment preferentially attacks the portions of the surface that are richer in the more reactive materials - again resulting in pitting.
What are the differences between physical and chemical weathering and say what type acid rain is?
1. Acid rains produce a chemical weathering.2. Chemical weathering involve chemical reactions.
