==Key Stage 3==
===Meaning===
A [[metamorphic]] [[rock]] is a [[rock]] that has formed from another [[rock]] being transformed underground by high [[temperature]] and [[pressure]].

===About Metamorphic Rocks===
: Most [[metamorphic]] [[rock]]s are formed from [[sedimentary]] [[rock]]s but some can be formed from [[igneous]] [[rock]]s.
: [[Metamorphic]] [[rock]]s are usually softer than [[igneous]] [[rock]]s but harder than [[sedimentary]] [[rock]]s.
: [[Metamorphic]] [[rock]]s have interlocking [[Grain (Rock)|grain]]s that usually look squashed because of the [[pressure]] underground.
