Metamorphic Rocks Overview

Flashcards covering key concepts about metamorphic rocks, their formation, and characteristics.

Metamorphic Rocks

Rocks that change underground due to heat and pressure without melting.

Definition of 'Metamorphic'

Changing.

Formation Causes of Metamorphic Rocks

Heat and pressure.

Do Metamorphic Rocks Melt?

No.

Types of Rocks that Become Metamorphic

Igneous and sedimentary.

Where do Metamorphic Rocks Form?

Underground.

Mineral Changes During Metamorphism

They change due to heat and pressure.

Uplift

The process that brings metamorphic rocks back to the surface.

Foliated Metamorphic Rocks

Rocks with layers or bands caused by pressure.

Cause of Foliation

Pressure.

Examples of Foliated Rocks

Slate, Schist, Gneiss.

Non-Foliated Metamorphic Rocks

Rocks with no layers formed mostly by heat.

Cause of Non-Foliated Rocks

Heat.

Examples of Non-Foliated Rocks

Marble, Quartzite.

Origin of Marble

Marble comes from limestone.

Origin of Quartzite

Quartzite comes from sandstone.

Origin of Slate

Slate comes from shale.

Origin of Gneiss

Gneiss comes from granite.

Effect of Pressure on Rocks

Leads to foliated rocks.

Effect of Heat on Rocks

Leads to non-foliated rocks.

What Happens if a Rock Melts?

It becomes an igneous rock.
