Question

Which of these is an example of chemical weathering?

Group of answer choices

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

Answer 1

The answer is B. Rocks breaking due to acid rain.

Step-by-step explanation:

Chemical weathering is the breaking down of minerals due to any chemical substance in the form of rain or any type of possible weather that can be categorized in this (chemical weathering) section.

Acid is a chemical and this can also form a reaction that is dissolved in water, and causes the breaking down of rocks to the touch of acid rain.

Answer 2

Answer: (B) Rocks breaking up due to acid rain.

Explanation: Carbonation is another type of chemical weathering. Carbonation is the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves. Dissolved carbon dioxide in rainwater or in moist air forms carbonic acid, and this acid reacts with minerals in rocks.
