Which step is part of the formation of a batholith? Heat and pressure change a pluton into metamorphic rock. A single pluton enl
arges into a huge mass by melting the rock around it. Lava flows across a mountain or plain, and then hardens into rock. Many plutons clump together as they rise through the crust.
The step that is part in the
formation of the batholiths is a single pluton enlarges into a huge mass by melting
the rock around it. A single pluton does not enlarge into a huge mass, instead,
it will melt due to the buoyant magma that surrounds it.
