lava or magma cools

water and ice collect small stones together and make a solid mass

iguanas produce fossilised dung

the pressure under the earth turns another rock type into an igneous one

lava or magma cool to create rock

pressure or heat change another rock type

layers of sediment press down hard and stick together. Different layers can be seen in the rock.
