Rock Cycle Diagram

The first mold is magma then Weathering is the process where the rock  is dissolved, worn away or broken down into smaller and smaller pieces. There are mechanical, chemical and organic weathering processes.Erosion is the act in which earth is worn away,often by water wind or ice . A similar process weathering breaks down or dissolves ,rock weakening it or turning it or turning it into tiny fragments. In sediment refers to compaction the process by which a sediment progressively loses its porosity due to the effects of loading. This forms part of the process of lithification cementation, in geology, hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock. Metamorphic Rock- Metamorphic rocks form when sedimentary, igneous, or other metamorphic rocks are subjected to heat and pressure from burial or contact with intrusive or extrusive igneous rocks.
