Hello mate
Explanation:
Weathering - the disintegration and decomposition of rock at or near the surface of the earth. It affects the rocks in place and no transport is involved. This distinguishes weathering from erosion.
Disintegration involves the breakdown of rock into its constituent minerals or particles with no decay of any rock-forming minerals. Rock alteration usually involves chemical weathering in which the mineral composition of the rock is changed, reorganized, or redistributed.
Disintegration of rocks by weathering processes produces three types of weathering products: detrital material from the rock and vegetation; solutes from the dissolution of minerals and organic matter; and new minerals from chemical reactions between solutes and minerals.
