1. Acid rains produce a chemical weathering.
2. Chemical weathering involve chemical reactions.
Acid rain is part of chemical weathering.
Chemical Weathering
chemical weathering change will most likely make a new substance
occures when the chemical comosition of the rock changes
Physical changes are reversible changes, such as change of state (boiling, melting etc), chemical changes are when something undergoes a reaction changing it's chemical makeup.
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.
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.
physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
physical: water, wind, and temperature chemical: acid rain and rust
Physical weathering is: frost, crystallization, exfoliation,, biological and pressure release. Chemcal weathering: anything with chemicals in it like carbonation, hydrolysis, solution, oxidation and hydration.
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.

The differences are that mechanical weathering breaks rocks into little pieces.. Chemical weathering not only breaks the rock but dissolves it.
Chemical weathering is which makes new substances, whereas physical weathering is where rock is changed into smaller pieces of the same substance.

A chemical change results in a change in chemical composition, while a physical change does not.
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.
physical change are reversable
