Which process causes rocks at the earth's surface to change form?
[ "bleaching", "weathering", "remodeling", "eroding" ]
B
Weathering changes solid rock into sediments. Sediments are different sizes of rock particles. Boulders are sediments; so is gravel. At the other end, silt and clay are also sediments. Weathering causes rocks at the Earth’s surface to change form. The new minerals that form are stable at the Earth’s surface.
