What are the answers for lesson 14 what causes chemical weathering?
Chemical weathering is caused by processes such as oxidation, carbonation, hydration, and hydrolysis. These processes involve chemical reactions that break down rocks and minerals into smaller particles through exposure to water, air, and other chemicals in the environment. Chemical weathering can lead to the alteration of mineral compositions and the formation of new minerals.
What does chemical weathering always form?
Chemical weathering always forms new minerals through the breakdown and alteration of pre-existing rocks due to chemical reactions with water, oxygen, or other substances in the environment.
What is the importance of water to chemical weathering?
Water plays a crucial role in chemical weathering by acting as a solvent that helps to break down rocks and minerals. Water can dissolve minerals, carry away weathering products, and facilitate chemical reactions that further break down rocks. Without water, chemical weathering processes would be significantly slower or nonexistent.
Is water a cause of physical weathering or chemical weathering?
It is a cause of both.
What is the process that breaks down rocks chemically?
Chemical weathering is the process that breaks down rocks by altering their chemical composition through reactions with substances like water, oxygen, and acids. This process can result in the transformation of minerals within the rock, leading to its decomposition and eventual disintegration.
Does chemical weathering involve water?
Yes, chemical weathering often involves water. Water can act as a solvent and reactant in various chemical processes that break down rocks and minerals. Water can also transport dissolved ions and molecules, aiding in the weathering process.
Is weathering rocks chemical or physical change?
Weathering of rocks can involve both chemical and physical changes. Physical weathering involves the breakdown of rocks without changing their chemical composition, while chemical weathering involves the alteration of a rock's chemical composition through reactions with water, air, or other substances.

Chemical weathering always forms new minerals through the breakdown and alteration of pre-existing rocks due to chemical reactions with water, oxygen, or other substances in the environment.
Does physical weathering always invovle water?
No, physical weathering does not always involve water. It can also occur through processes such as temperature changes, wind, ice, and plant roots breaking down rocks without the presence of water.
What are some similarities and differences between physical and chemical weathering?
Similarities: Both processes result in the breakdown of rocks and minerals. Both can occur through natural processes like temperature changes, water, and biological activity. Differences: Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the chemical composition of rocks through reactions with substances like water or acids. Physical weathering does not involve chemical reactions, while chemical weathering does.
What type of weathering caused by chemical reaction in water?
Chemical weathering is the type of weathering caused by chemical reactions in water. This process involves the breakdown of rocks and minerals through chemical reactions with water, leading to the alteration of the rock's composition. Examples of chemical weathering processes in water include hydration, hydrolysis, and oxidation.
Which process can bring about chemical weathering?
Chemical weathering is primarily driven by processes such as oxidation, hydrolysis, and carbonation. These processes involve the breakdown of rocks through chemical reactions with substances like oxygen, water, and carbon dioxide, leading to the alteration or dissolution of minerals in the rock.
How are physical weathering and chemical weathering alike and different?
Physical weathering and chemical weathering both involve the breakdown of rocks, but through different processes. Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their composition, while chemical weathering involves the alteration of rock composition through chemical reactions with substances like water, oxygen, and acids. Both processes contribute to the overall erosion of rocks and landforms over time.
What is the importance of water to chemical weathering?

Water can dissolve minerals, carry away weathering products, and facilitate chemical reactions that further break down rocks. Without water, chemical weathering processes would be significantly slower or nonexistent.
The decomposition of rock from exposure to water and atmospheric gases is known as?

What are the three agents of chemical weathering?
water,acids and air are all agents of chemical weathering
