This rock is a sediment rock. Hes in the lava .(in a volcano.)
the rock melts back into magma.
as the volcano exsplodes the rock flies out and turns harder into a ignues rock!
when the rock is in the air it's surrounded with other sediments,then the rock Cools and crystals.
then the rock lands in water and years of weathering and erosion it turns into a single sediment.after that happens it somehow falls deep in the middle of the world and the rock gets pressured,after that happens it pushes the rock closer to lava.the lava heats the rock that turns the rock into a metamorphic rock.
