Chemical changes produce weathering by altering the minerals in rocks through chemical reactions with environmental agents like water, acids, and gases. For example, carbon dioxide can dissolve in water to form carbonic acid, which can then react with minerals like calcite, leading to their breakdown. This process weakens the rock structure and facilitates further physical weathering. Additionally, oxidation of minerals, such as iron, can cause discoloration and structural changes, contributing to the overall weathering process.

What are two ways that chemical weathering changes rocks?
Physical and Chemical
What is the principal difference between weathering and chemical weathering?
The principal difference between weathering and chemical weathering is that weathering involves physical processes that break down rocks into smaller pieces without changing their chemical composition, while chemical weathering involves chemical reactions that alter the mineral composition of rocks.
What are the differences between physical and chemical weathering and say what type acid rain is?
Physical weathering involves the breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering involves the alteration of rocks through chemical reactions. Acid rain is a form of chemical weathering, as it can react with rocks and minerals to degrade them.
Does mechanical weathering change a rocks chemicals?
Mechanical weathering does not change a rock's chemical composition; it only breaks the rock into smaller pieces. Chemical weathering, on the other hand, alters a rock's chemical composition through processes like oxidation, hydrolysis, and dissolution.
Is weathering a physical or chemical change?
Weathering can involve both physical and chemical changes. Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, such as through freezing and thawing. Chemical weathering, on the other hand, alters the chemical makeup of rocks through processes like oxidation or dissolution.
What are the chemical of weathering?
it harms the environment. temperature changes and climate changes occur because of chemical weathering.
How are machanical and chemical weathering different?
Mechanical weathering is a process which physically changes the appearance of a rock or structure. Chemical weathering is a process which changes the chemical composition of a rock or structure.
What produce chemical weathering?
oxidation
What types of weathering that does not cause chemical changes?
mechanical weathering
What type of weathering is the process that breaks down rock through chemical changes?
Chemical Weathering
What type of weathering actually changes the composition of rocks?
Chemical Weathering
What is a type of weathering that changes rock into one or more substances?
Chemical weathering
Chemical Weathering?
In chemical weathering, rocks are broken down, and their composition changes. Chemical weathering is caused by water, oxidation, carbon dioxide, organisms, and acid rain.

What does chemical weathering of feldspar produce?
clay minerals
What are non-examples of mechanical weathering?
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
How does igneous rock changes into sedimentery rock?
By weathering either by physical or chemical weathering.
