An incomplete diagram of the rock cycle is shown below. Use the labels to correctly complete the diagram.

Rock cycle is a process through which one form of rock is converted to another one. There are three types of rocks in rock cycle i.e., igneous rock, metamorphic rock, and sedimentary rock. Each of these rock can change into the other kinds by physical processes: cooling, melting, heat, weathering/erosion, compacting (squeezing tightly together). cementing, and pressure.

When heated deep under ground, rocks become magma(liquid rock). when magma comes to ground it is called lava. Weathering and erosion forms sediments, this sediments form sedimentary rocks in future.

So, the answer for this question is

sedimentary rock> pressure and heat > metamorphic rock> melting

sedimentary rock > weathering and erosion > sediment

igneous rock > metamorphism > metamorphic rock

sedimentary rock -> Pressure and heat -> metamorphic rock -> melting

sedimentary rock -> erosion -> sediment

igneus rock -> crystallization -> metamorphic
