Types of Rocks Lesson

What are the 3 major types of rocks?

• Igneous, Metamorphic, Sedimentary

• Metamorphic, Igneous, Cementation

• Brown, Red, Gray

• Streak, Hardness, Breakage

This rock was found near the mouth of a volcano. What type of rock is this?

• Sedimentary

• Igneous

• Metamorphic

This rock was formed when magma cooled very slowly inside the Earth. What specific type of rock is it?

• Intrusive Igneous Rock

• Extrusive Igneous Rock

• Foliated Metamorphic Rock

• Clastic Sedimentary Rock

This rock formed when lava cooled very quickly on Earth's surface. What specific type of rock is it?

• Extrusive Igneous Rock

• Intrusive Igneous Rock

• Non-Foliated Metamorphic Rock

• Biochemical Sedimentary Rock

The three groups of rocks are classified by

• How they form

• Color

• Grain size

• Chemical Composition

Cooling & crystalization produce

• igneous rocks

• metamorphic rocks

• sedimentary rocks

What process is used to form sedimentary rocks?

• Lava cools and hardens to form a rock.

• Weathering, Erosion, Deposition, Compaction, Cementation

• Extreme heat and pressure from inside the Earth turn rocks into new rocks.

• Magma trapped under the Earth's surface cools and solidifies.

Extreme Heat and Pressure creates a _________ rock.

• Igneous

• Metamorphic

• Sedimentary

• Mineral

Granite forms what type of metamorphic rock?

• slate

• marble

• gneiss

• quartzite

metamorphic rocks have mineral grains that are not arranged in distinct bands.

• Conglomerate

• Non-foliated

• Foliated

• Permeated
