Rock Cycle

Rock Cycle= A rock cycle is that all rocks change from one kind to another which is the rock cycle. For an example this is the way the rock cycle goes.  First the lava and magma makes Igneous rocks then the sand turns it to Sedimentary rock then to Metamorphic Rocks and finally back the lava and magma. Some rocks like slate change when the temperatures are around 392 Fahrenheit  they are called low-grade Metamorphosis. If it’s higher than 392 degrees Fahrenheit they are called high-grade Metamorphosis.
