Metamorphic Rocks Quiz

Formed from sedimentary or igneous rocks through increasing pressure and temperature.
Major types include slate, phyllite, schist, and gneiss.

Mudstone/Shale:
- A sedimentary rock composed primarily of mud.
Slate:
- A metamorphic rock originating from mudstone.
- Characterized by no visible crystals and lacks shininess.
Phyllite:
- Also derived from mudstone.
- Lacks visible crystals but exhibits some shininess.
Schist:
- Resulting from mudstone with visible crystals.
Gneiss:
- Formed from mudstone and identified by its zebra-stripe pattern.
Migmatite:
- Derived from mudstone, recognized by its swirly/melty appearance.

Granite:
- An igneous rock from granitic magma; common and widely distributed.
Quartz/Sandstone:
- A sedimentary rock formed from sand particles.
Quartzite:
- A metamorphic rock resulting from the alteration of quartz/sandstone.
Carbonate/Limestone:
- Composed primarily of calcium carbonate from coral skeletons; a sedimentary rock.
Marble:
- A metamorphic rock formed from carbonate, typically derived from limestone.
Basalt:
- An igneous rock originating from basaltic lava; also common.
Greenstone/Greenschist:
- A metamorphic rock produced from basalt under low pressure and temperature conditions.
Amphibolite:
- Another metamorphic rock from basalt, transformed under high pressure and temperature.
Gabbro:
- An igneous rock from basaltic magma; noted for its rarity.
Granitic Gneiss:
- A metamorphic rock formed from granite, developed under high pressure and temperature.
