Which rock was subjected to intense heat and pressure but did not solidify from magma?

The correct answer is:

Metamorphic rocks

Explanation:

Metamorphosis is the difference that succeeds when rocks under the earth's surface are measured by total heat and pressure, manipulating them into metamorphic rocks. A metamorphic rock is a result of a reduction of a pre-existing rock. The fundamental rock is constrained to very great heat and pressure, which create obvious physical and/or chemical changes. Representatives of these rock types combine marble, slate, gneiss, schist.
