What is the diffence between chemical weathering and physical weathering?
Wiki User
∙ 12y ago
Chemical and biological weathering are different because:
a) biological weathering - this means that if a seed of a plant gets coincidentally deposited in a crack in a rock, if it is humid enough, the see will grow. it's roots will spread out and eventually break the rock.
b) chemical weathering - this means that chemicals in rain/acid rain weathers away the rock.

∙ 11y agoPhysical weathering applies when a rock surface is rubbed away by some physical force. Examples would include
• wearing smooth of river rocks by continuous flow of water (over a very long time)
• sand blasting of rocks in desert storms
• tumbling of coastal stones together by wave action
• gouging of rocks by glaciers.
• splitting of rocks by water filling cracks and then expanding as it freezes.
Chemical weathering applies when a rock is eroded away by some sort of chemical reaction. Examples would include
• acidity in rain or streams reacting with limestone to make carbon dioxide and soluble calcium salts
• acidic secretions from lichens or mosses dissolving away alkaline portions of granites and similar materials (feldspars and plagioclases)

∙ 12y agoChemical involves Chemistry, but Physical includes Geography (physical).
Chemical weathering is mostly rain-related. Acid rain is noted in particular for the destruction of basic rocks like Limestone. Rain in general is responsible for the dissolution of sedimentary cements, especially in Sandstones.
Physical weathering ranges in forms, including ex-foliation, freeze-thaw and biological. This results in often visible changes, compared to chemical which sometimes leaves no sign at all.
A comparison leads to the conclusion that chemical is related to the chemical reactions and dissolution of minerals, whereas physical is more related to the physical changes made to an environment by physical factors and processes.

∙ 11y agophysical weathering can be breakdown of a rock from a stream that the rock is in witch will slowly break it and make it round and smooth.
chemical could be acid rain or rusting witch breaksit down also.

∙ 11y agoBiological weathering is when a rock is eroded by an animal or plant (a living thing) but physical weathering is when the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.

∙ 11y agophysical weathering is freeze thaw and exfoliation or onion skin weathering, chemical weathering is acid rain and biological is plants and animals.

∙ 11y agochemical weathering is when the colour changes
physical weathering is when the shape changes

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.
What is the difference between physical and chemical weathering change?
chemical weathering change will most likely make a new substance
What is the principal difference between weathering and chemical weathering?
occures when the chemical comosition of the rock changes
What is similar between physical and chemical weathering?
Both types of weathering cause rocks and other solid materials to break apart/break down. Both types of weathering are the start of erosion processes.
How can you tell the diffence between water and a chemical?
Add dye or food coloring you may see a diffence in color. The water may take longer to have the dye take over. Your cheimcal may not or there is no color.
What is the difference between a chamical and physical change?
The diffence between chemical and physical is that ones chemical and ones physical!!
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.
What the differences between physical weathering and surface waters?
physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
What is the diffence between a physical and chemical change?
Physical change doesn't produce a new substance, but a chemical change is 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 physical and chemical weathering and say what type acid rain is?
1. Acid rains produce a chemical weathering.2. Chemical weathering involve chemical reactions.
What is the difference between physical and chemical weathering change?
chemical weathering change will most likely make a new substance
What are differences between physical and chemical weathering?
physical: water, wind, and temperature chemical: acid rain and rust
What is the difference between siliciclastic and chemical or biochemical sedimentary rocks?
1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What is the differences between physical weathering and chemical weathering of granite?
Physical weathering is: frost, crystallization, exfoliation,, biological and pressure release. Chemcal weathering: anything with chemicals in it like carbonation, hydrolysis, solution, oxidation and hydration.
What similarities between physical and chemical weathering?
they both break down stuff into fragments.p.s : this is the right answer.
