Chemical weathering
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.

mechanical weathering
Chemical weathering causes the mineral composition of a rock to change. This process involves the breakdown of minerals in the rock due to chemical reactions with water, oxygen, or acids in the environment. Over time, these reactions can alter the original minerals into different ones.
Yes, weathering is the process by which rocks are broken down and their mineral composition can be altered. This can occur through physical weathering (mechanical breakdown of rocks) and chemical weathering (alteration of minerals through chemical reactions with water, oxygen, or other substances). Over time, this process can lead to the formation of new minerals and the breakdown of original mineral compositions in rocks.
Physical weathering, such as frost wedging or root wedging, does not alter the mineral composition of a rock. These processes break down rocks into smaller pieces without changing their chemical makeup.
Physical weathering is caused by mechanical forces such as temperature changes, frost wedging, and abrasion, while chemical weathering involves the breakdown of rock through chemical reactions like oxidation and hydrolysis. Physical weathering does not change the chemical composition of the rock, whereas chemical weathering alters the mineral structure.
Physical weathering, also known as mechanical weathering, does not change the composition of the rock. This process involves the breaking down of rocks into smaller pieces through physical forces such as temperature changes, freezing and thawing, or abrasion. While the size and shape of the rock may change, its mineral composition remains the same. Examples include frost wedging and thermal expansion.
The process is called metamorphism, the alteration of chemical composition or structure due to heat and/or pressure.
The change of rocks and minerals into smaller particles without a change in composition is known as mechanical weathering. This process involves physical forces such as freeze-thaw cycles, abrasion, and temperature fluctuations that break down rocks into smaller fragments. Unlike chemical weathering, mechanical weathering does not alter the mineral composition of the rocks, preserving their original materials while changing their size and shape.
