The jointed rocks weather to form roughly spherical shapes. C. Biological weathering Organisms can assist in breaking down rock into sediment or soil. This series describes the order in which silicate minerals weather. Minerals which form at lower temperatures and pressures are most stable. The order of mineral stability in the weathering environment is the same order as Bowen's Reaction Series.
Weathered rock is called saprolite .
Weathered rock fragments are one of the constituents of soil . Quartz grains may be eroded, becoming sediment. Clays will ultimately be eroded and washed out to sea.
