Sedimentary rocks protect proof, as fossils, of past life on Earth.
The sediments sort layers; layers in the vicinity of the bottom are compacted by the weight of levels over. Water moving with the levels deposits minerals, which cement the sediments with each other to form sedimentary rock. These sedimentary rock levels, if exposed to heat and stress at convergent plate boundaries, are remodeled to metamorphic rock. Subducted metamorphic rocks melt as They are really pushed deeper into Earth at subduction zones. The melted rock varieties magma. The igneous rock shaped from cooled magma or lava may possibly stick to a very diverse route in the rock cycle the next time.
Metamorphic rocks are shaped when rocks are subjected to heat, pressure, or the two warmth and strain. Metamorphic rocks usually kind at plate boundaries and beside intrusions of magma. Sedimentary rocks are fashioned from weathered bits of rocks (sediments). These sediments are deposited into layers. The weight of overlying levels compact the layers of sediment down below, and water flowing with the layers check deposits minerals that cement the grains together.
