Rocks

A model that describes the formation, breakdown, and reformation of a rock.

• Fall Zone

• Weathering/ Erosion/ Deposition

• Rock Cycle

• Soil Profile

Rock formed from sediments, such as sand, pebbles, shells and remains of dead plants / animals; often deposited in layers

• Regolith

• Sedimentary Rock

• Igneous Rock

• Metamorphic Rock

Rock formed from liquid molten rock (lava or magma) that cools slowly and hardens. Found near volcanoes and fissures; can have crystals.

• Metamorphic Rock

• Igneous Rock

• Sedimentary Rock

• Regolith Rock

Fossils (the remains or impressions of prehistoric organisms preserved in petrified form or as molds or casts) are found in ___________ rocks only.

• Igneous

• Metamorphic

• Sedimentary

• Iron Oxide

The process necessary to form a metamorphic rock:

• uplift, weathering, erosion

• heat and or pressure

• burial and cementation

• compaction

A rock consists of two or more minerals.

• True

• False

There are ________ different types of rock that all basically come from the same materials.

• two

• three

• four

• many

_________ rocks harden into rock layers due to pressure of water and weight of more sediments.

• Metamorphic

• Igneous

• Sedimentary

• Volcanic

Physical properties of igneous rock include

• cementation of smaller rocks

• layers

• crystals

• ribbons

Sedimentary rocks are broken down by:

• lithification

• weathering

• erosion

• plants and animals
