FranThe four causes of weathering are physical weathering (breakdown of rocks into smaller pieces by physical processes like freezing and thawing), chemical weathering (breakdown of rocks through chemical processes like oxidation and dissolution), biological weathering (breakdown of rocks by living organisms like plants and animals), and erosion (transportation of weathered material by wind, water, or ice).

What are the three main causes of weathering?
The three main causes of weathering are physical weathering (e.g. wind, water, and ice), chemical weathering (e.g. oxidation and hydrolysis), and biological weathering (e.g. plant roots and burrowing animals). These processes break down rocks and minerals into smaller particles over time.
How many main causes cause mechanical weathering?
There are two main causes of mechanical weathering: frost action and abrasion. Frost action occurs when water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart. Abrasion happens when rocks are physically broken down by forces like wind, water, or glaciers.
What are the 7 main causes of weathering?
The seven main causes of weathering are thermal expansion and contraction, ice wedging, plant roots, abrasion, animal activity, dissolution, and oxidation. These processes contribute to the breakdown and erosion of rocks and minerals over time.
What is the weathering and its main causes?
Weathering is the process where rocks and minerals are broken down into smaller pieces through exposure to elements like water, wind, and temperature changes. The main causes of weathering are physical processes (mechanical weathering) like freeze-thaw cycles and abrasion, as well as chemical processes (chemical weathering) such as oxidation and hydrolysis.
Which type of weathering causes the mineral composition of rocks to change?
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.
