How and why do rocks disintegrate to form sediment?
What will be an ideal response?
Answer: Weathering is the interaction of the geosphere with the atmosphere, hydrosphere, and biosphere. Physical weathering disaggregates rocks by mechanical means. The most effective agent of physical weathering is the freezing and thawing of water. Other processes include salt weathering, cracks formed by temperature-induced expansion and contraction, and tree roots growing in rocks. Chemical weathering occurs when minerals react with water and oxygen. The two products of chemical weathering are ions dissolved in aqueous solutions and new minerals formed by hydrolysis and oxidation.
