Question

what is carbonation and exfoliation ​

Answer 1

Answer:

Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common.

Exfoliation is the term used to describe the peeling away of sheets of rock millimeters to meters in thickness from a rock's surface due a range of physical and chemical processes during exhumation and weathering . Exfoliation can occur due to several processes

Answer 2

Exfoliation:

The first type of weathering is exfoliation, also called unloading, which is when the outer layers of rock break away from the rest of the rock

Example of exfoliation is Half Dome in Yosemite National Park, which formed after glaciers caused surface rock to be removed.

Carbonation:

It 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.
