explanation of the rock cycle
What is melted rock cools into igneous rock. igenous rock breaks into sediments due to weathering. sediments form into sedimentary rocks. sedimentary rocks change into metamorphic rocks due to a change in heat, pressure, or chemical change. metamorphic rock melts and turns back into melted rock
