A   variety of  weathering  processes cause rock to break down into smaller  particles at the earth's surface.  Physical weathering  is the disintegration of rock into smaller fragments of the  same mineral composition by processes such as f rost action salt-crystal  growth  and  unloading Chemical weathering  is the decomposition of rock resulting from mineral  alteration processes such as  hydrolysis oxidation  and  solution Over much of the land surface, the underlying bedrock is covered by a layer of  weathered material called
