PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water can combine with gases like oxygen, carbon dioxide, and sulfur to dissolve minerals in rocks like limestone and marble. This creates rock particles that have a different mineral makeup from the rock they came from. This process is called-
A
mechanical weathering
B
chemical weathering
C
ice wedging
D
erosion
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Chemical Weathering Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.

Detailed explanation-3: -Carbonation is the process of rock minerals reacting with carbonic acid. A weak acid formed when water combines with carbon dioxide. is formed when water combines with carbon dioxide. Carbonic acid dissolves or breaks down minerals in the rock.

Detailed explanation-4: -Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.

Detailed explanation-5: -Hydrolysis Rock-forming minerals like amphibole, pyroxene, and feldspar react with water and form different kinds of clay minerals.
