   What is chemical weathering?

   • Chemical weathering, also known as decomposition or decay, is the breakdown of rock by chemical mechanisms. Chemical weathering does not break rocks into smaller fragments through wind, water, and ice (that's physical weathering). Nor does it break rocks apart through the action of plants or animals (that's biological weathering).

   How does chemical weathering change the composition of rocks?

   • “ Chemical weathering changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions. Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment.

   What are some examples of chemical weathering?

   • Karst features are a common example of this phenomenon. Oxidation is another type of chemical weathering. Oxidation is also known as rusting. It is the process whereby the rock minerals lose one or more ions or atoms in the presence of oxygen. When minerals in the rock oxidize, they become less resistant to weathering.

   Which chemical reactions are important for chemical weathering?

   • These reactions include hydrolysis, carbonation, dissolution, and oxidation. Temperature and most importantly moisture are vital for chemical weathering. Hydrolysis is the chemical reactions caused by water. Water reacts with the rock and alters the size and chemical compositions of the minerals, lessening their resistance to weathering.

   What types of weathering affect rock?

   • There are three types of weathering which affect rock: physical, biological, and chemical. Chemical weathering, also known as decomposition or decay, is the breakdown of rock by chemical mechanisms. Chemical weathering does not break rocks into smaller fragments through wind, water, and ice (that's physical weathering).

   What is physical weathering?

   • Also known as mechanical weathering, physical weathering involves the breakdown of rocks and minerals into smaller pieces without changing their chemical composition. Various environmental factors drive this process, including temperature fluctuations, pressure changes, and biological activity.

   Chemical weathering describes the process of chemicals in rainwater making changes to the minerals in a rock. Carbon dioxide from the air is dissolved in rainwater, making it slightly acidic. A reaction can occur when the rainwater comes into contact with minerals in the rock, causing weathering.
