Forms from melted rock that cools.

Define Igneous Rock:

1. Extrusive
2. Intrusive

What are the two types of Igneous Rocks?

Formed from lava when it cools (Outside Volcano).

How are Extrusive Igneous Rocks formed?

1. Cools Fast

2. Smooth Surface

3. Small Crystals

4. Usually Dark Colored

What are four facts about an Extrusive Igneous Rocks:

Formed from magma when it cools (Inside/Under Earth's Surface).

How are Intrusive Igneous Rocks formed?

1. Cools Slow

2. Large Crystals

3. Usually Light Colored

What are three facts about an Intrusive Igneous Rocks:

Intrusive Igneous Rock

Identify the correct Igneous Rock:

I Cool Slow.

Extrusive Igneous Rock

Identify the correct Igneous Rock:

I have a Smooth Surface.

Intrusive Igneous Rock

Identify the correct Igneous Rock:

I form Inside/Under the Earth's Surface.

Extrusive Igneous Rock

Identify the correct Igneous Rock:

I Cool Fast.

Extrusive Igneous Rock

Identify the correct Igneous Rock:

I form Outside Volcanoes.

Extrusive Igneous Rock

Identify the correct Igneous Rock:

I am usually Dark Colored.

Intrusive Igneous Rock

Identify the correct Igneous Rock:

I form from Magma when it Cools.

Intrusive Igneous Rock

Identify the correct Igneous Rock:

I have Large Crystals.

Intrusive Igneous Rock

Identify the correct Igneous Rock:

I am usually Light Colored.

Extrusive Igneous Rock

Identify the correct Igneous Rock:

Extrusive Igneous Rock

Identify the correct Igneous Rock:

I have Small Crystals.

Broken rock, shell, parts, etc. that are carried by rivers, ocean waves, mud slides, glaciers and the wind.

Define Sediment:

It collects into layers.

What happens when Sediment is dropped or deposited?

Thousands of years.

How long does it take for Sedimentary Rocks to form?

Stratification

What is the most characteristic feature of Sedimentary Rocks?

Layering of rock.

Define Stratification:

Strata

What are the Sedimentary layers of rock called?

Younger rocks lie above older rocks in undisturbed sequences.

Define Principle (Law) of Superposition:

Change of Form.

Define Metamorphic:

Form when existing rocks are heated or squeezed; they recrystalize.

When do Metamorphic Rocks form:

1. Might change chemically.

2. Usually occurs deep below surface of Earth at high temperature and pressures.

3. New Metamorphic Rocks can form from any existing type of rocks
- Igneous
- Sedimentary
- Metamorphic

List 3 facts about Metamorphic Rocks:

Chemically

What is one way a Metamorphic Rock might change?

Deep below surface of Earth at high temperature and pressure.

Where does the change of the Metamorphic Rock usually occur?

Any existing type of rocks (Igneous, Sedimentary, Metamorphic).

Where can new Metamorphic Rocks form from?

They recrystalize.

What happens after a Metamorphic Rock forms?
