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.
What reacts with water to dissolve rocks such as marble and limestone?
Carbon dioxide reacts with water to form carbonic acid, which then reacts with minerals in rocks like marble and limestone, causing them to dissolve. This is known as carbonation weathering and is a common process in the dissolution of carbonate rocks.
What type of rocks dissolve in rainwater?
Sedimentary rocks, particularly limestone and marble, are most susceptible to dissolving in rainwater due to their calcium carbonate content. When rainwater, which can be slightly acidic due to dissolved carbon dioxide, comes into contact with these rocks, it reacts chemically and leads to dissolution. This process can result in the formation of features such as caves and sinkholes. Other rocks, like gypsum, can also dissolve in rainwater but to a lesser extent.
What type of rock is chemically weathered by acidic groundwater?
Limestone is a type of rock that is chemically weathered by acidic groundwater. The acidity, often due to dissolved carbon dioxide forming carbonic acid, reacts with the calcium carbonate in limestone, leading to its dissolution. This process can create features such as caves and sinkholes in karst landscapes. Other carbonate rocks, like marble, can also be affected similarly.
How does carbonation chemically weather rocks?
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 is carbon dioxide released into the air by carbonate rocks?
Carbonate rocks, like limestone, can release carbon dioxide when they break down or weather. This process, known as chemical weathering, occurs when carbonic acid in water reacts with the minerals in the rocks, leading to the release of carbon dioxide into the air.
What is formed as rainwater reacts with carbon dioxide in the soil?
When rainwater reacts with carbon dioxide in the soil, it forms carbonic acid. This weak acid can further contribute to the weathering of rocks and minerals in the soil.

What gas is given off when acid reacts with rocks?
The most common one would be carbon dioxide, which is given off when strong acids react with rocks containing carbonates.
What is formed as rainwater reacts to carbon dioxide in the soil?
Carbonic acid is formed when rainwater reacts with carbon dioxide in the soil. This weak acid plays a role in the chemical weathering of rocks and minerals. Over time, carbonic acid can contribute to the formation of caves, sinkholes, and other geological features.
WHAT following rocks IS reacts with an acid?
Without the list of rocks we cannot respond to this question.

How did carbon dioxide end up in sedimentary rocks?
Carbon dioxide is dissolved into the sea. Marine organisms use the dissolved carbon dioxide to make shells of calcium carbonate. When these organisms die, they fall to the sea bed. Layers of dead organisms and sediment build up on the sea bed. These layers are compacted and compressed to form sedimentry rock.
How is carbon dioxide put into rocks?
Carbon dioxide can form carbonates when it react with a basic substance
