Which of these is an example of chemical weathering?
a- sediments blowing away by air
b- rock breaking up due to acid rain
c- rock breaking up due to mechanical force
d- sediments settling down in a new location
this is for science !

The correct answer is B- Rock breaking up due to acid rain

Explanation:

Chemical weathering occurs as rocks or minerals interact with other substances and this leads to a chemical reaction that breaks or dissolves the rock or mineral. Moreover, this differs from physical weathering because, in this, rocks or minerals do not react with other substances, and therefore there is not a chemical change.

Rock breaking up due to acid rain is an example of chemical weathering because the carbon dioxide in the acid rain triggers a chemical reaction in the rock, as the carbonic acid in the acid rain (H2CO3) interacts with the calcium carbonate (CaCO3) and these leads tot he formation of new substances including calcium carbonate. This means through a chemical reaction the rock or mineral dissolves or breaks and changes its composition.

the answer is alpha particles hope i you

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
