The Rock Cycle

The texture of a Igneous rock could be fine-grained or coarse-grained. In order for it to be fine-grained, there needs to be rapid cooling and small crystals will form. For coarse grained to form, there needs to be slow cooling and large crystals will form. Granite is coarse-grained rock and basalt is a fine-grained rock. clastic rock is a sedimentary rock that forms when rock fragments are squeezed together. Organic rocks are also sedimentary rocks that where he remains of plants and animals are deposited in thick layers. Finally chemical rocks are also sedimentary rock, but it forms when minerals that are dissolved in a solution crystalized.
As you can see from our diagram, the cycle starts as Metamorphic rock. It then melts into magma, the magma cools forming Igneous rock. If the magma. Next the Igneous rock goes through weathering and erosion and turns into sediment. Then the sediment goes through compaction and cementation and turns into Sedimentary rock then with heat and pressure the Sedimentary rock turns into Metamorphic rock then the rock cycle starts over again.
