Igneous rock can be transformed into metamorphic rock through what?

Answer 1

Usually it is sedimentary rock that is changed into metamorphic - however it is entirely possible for igneous rock to become metamorphic as well.

Metamorphic means different form, and in the geological since it mean rock that has been changed by heat and pressure. Now there isn't too much that can be done to igneous rock to change it chemically, by heat and pressure. But it can undergo physical distortions.

Answer 2

If an igneous rock is put under a great amount of pressure and heat, then it will metamorphic, or change into another rock. Then the rock that it started as will become known as the "parent rock".

Answer 3

Heat and pressure changes both igneous rocks sedimentary rocks into metamorphic rocks.

Answer 4

All igneous rocks change into metamorphic rockes when heated (and squashed).

Answer 5

The metamorphic rock melts into lava, which cools into igneous rock. Hope this helps :)

Answer 6

Melting and Cooling
