Ø Carbonation occurs on rocks which contain calcium carbonate such as limestone and chalk.
Ø Carbon dioxide dissolved in rainwater forms weaker carbonic acid that reacts with insoluble calcium carbonate, changing it into soluble bicarbonate. This takes place when rain combines with carbon dioxide or an organic acid to form a weak carbonic acid which reacts with calcium carbonate (the limestone) and forms calcium bicarbonate.
Ø The reactions as follows:
Ø CO2 + H2O => H2CO3
Ø Carbon dioxide + water => carbonic acid
Ø H2CO3 + CaCO3 => Ca (HCO3)2
Ø Carbonic acid + calcium carbonate => calcium bicarbonate

How acids in living things weather rocks?
The acids chemically weather rock by breaking up their chemical composition, which eventually causes the rock to lose mass by decomposition.
How can granite weather chemically?
Granite can weather chemically primarily through processes like hydrolysis, oxidation, and carbonation. During hydrolysis, feldspar minerals in granite react with water and carbon dioxide to form clay minerals and soluble ions, altering the rock's composition. Oxidation occurs when iron-bearing minerals in granite react with oxygen, leading to rusting and structural breakdown. Carbonation involves the reaction of carbonic acid (formed from carbon dioxide and water) with minerals, further contributing to the chemical weathering of granite.
What process will most likely chemical weather on iron-rich rocks?
The most likely process that will chemically weather iron-rich rocks is oxidation. When iron is exposed to oxygen and water, it can react to form iron oxide, commonly known as rust. This process weakens the rock structure and can eventually lead to the breakdown of the rock into smaller fragments.
How does carbon dioxide in the air weather rocks?
Carbonic acid reacts chemically with limestone, which is observed as weathering. As such, carbonic acid weathering is a chemical, not physical, change.
Plants are a factor in what weathering?
Plants contribute to physical weathering by breaking down rocks through their roots and by expanding as they grow, causing cracks in rocks. They also release acids that can chemically weather rocks. Overall, plants play a significant role in the weathering of rocks and landforms.
Why don't lunar rocks chemically weather?
No atmosphere-no weather.
Does wind weather rocks mechanically or chemically?
Mechanically
Do natural acids mechanically or chemically weather rocks?
Natural acids chemically weather rocks by reacting with minerals in the rock, causing them to break down. Mechanical weathering involves physical processes like freezing and thawing, which cause rocks to break apart without altering their chemical composition.
Does water break down rocks?
Water can chemically weather rocks by dissolving minerals, water can also physically weather rocks by fracturing them by hydraulic pressure or frost wedging.
How do oxygen chemically weather rocks?
There is no significant weathering from oxygen. However, the particles in the wind (oxygen) can weather a rock.
How does water break down?
Water can chemically weather rocks by dissolving minerals, water can also physically weather rocks by fracturing them by hydraulic pressure or frost wedging.
What can cause chemical weathering of rocks?
water, air, chemicals, ect Acid rain contains sulfuric acid that can chemically weather rocks.
What is wheatering?
weathering is the breaking down of rocks to form soil. it can be caused physically chemically or biologically. physically by ice, water, and other physical conditions chemically by solution, carbonation, hydration etc.. and biologically by human activities, animals or even plants
Are sedimentary rocks chemically weathered?
Sedimentary rocks can be both chemically and mechanically weathered.
