TYPES OF ROCKS

SEDIMENTARY

• Ash from volcanoes forms layers of sediment.
• Layers of sediment harden into rock.
• Some sedimentary rock wears away to form new layers of sediment

METAMORPHIC

• Heat and pressure change sedimentary rock into metamorphic rock.
• Heat melts metamorphic or sedimentary rock into magma deep within earth.

IGNEOUS

• Magma cools slowly beneath Earth's surface and hardens into igneous rock.
• Igneous rock under heat and pressure becomes metamorphic rock.
• Igneous and metamorphic rocks wears over time and forms layers of sediment.

COUCLUSION

• In conclusion metamorphic rock means to change or form.
• Metamorphic rocks can form from sedimentary rocks, igneous rocks, and even other metamorphic rocks.
• Sedimentary rocks form when layers of sediment settle on top of one another and harden.
• Igneous rocks form from magma.

OUR FAVORITE ROCK

• Our favorite rock is igneous.
• It is our favorite rock because the often have crystals that interlock.
