WebMetamorphism is the change that takes place within a body of rock as a result of it being subjected to conditions that are different from those in which it formed. In most cases, but not all, this involves the rock being deeply buried beneath other rocks, where it is subjected to higher temperatures and pressures than those under which it formed. WebAt plate boundaries, or hot spots, some rocks get heated deep inside the Earth and melt into ‘molten rock’. Molten rock is called magma when it is inside the Earth and lava when it is on the surface. As it cools, it crystallises and solidifies to form igneous rock. BGS © UKRI. Metamorphic rock.
