1. Unit 7: Earth Science—Three types of rock SPI 0707.7.1, 0707.7.2
Unit Objective: I can identify the three different types of rocks and create and interpret a rock cycle diagram.

2. Video Clip 25 Amazing Earth Facts!!!

3. Unit Vocabulary Rock-a solid substance made of two or more minerals
Igneous-rocks formed from “melted” rock
Sedimentary-rocks formed from “layers” of compacted sediment
Metamorphic-rocks “changed” due extreme heat and pressure
Rock Cycle-a series of processes that changes rocks over time
Melting-changing a solid to a liquid
Weathering/erosion-breaking down rocks and carrying pieces away

4. Where are ROCKs?
Rocks are everywhere!

5. What is a rock? Rocks can be classified by how they form:
A rock is a solid material from the Earth that is usually made up of one or more minerals…chocolate chip, monster, cookie.
Rocks can be classified by how they form:
-Igneous Rocks (“fire” “melted”)
-Sedimentary Rocks (“layers”)
-Metamorphic Rocks (“change”)

Igneous Rocks

7. Igneous Rocks
Note Taker #1!
Illustrator!
Igneous rock: born of fire, rock formed from “melted” rock, magma, or lava.
Extrusive Igneous-lava cools outside earth’s surface…small crystals
Intrusive Igneous- magma cools inside the earth…larger crystals

8. Igneous Rocks Extrusive (out) Intrusive (in)
Note Taker #1!
Extrusive (out)
Intrusive (in)
Rocks that have formed from Lava
The cooling and hardening process occurs on Earth’s surface
Rocks that have formed from magma
The cooling and hardening process occurs under Earth’s surface

9. Video Clip Sedimentary Rock

10. Sedimentary Rocks
Note Taker #2!
Illustrator!
Sedimentary rock: “layers” of rock formed from compaction and cementation of sediment.
Sediment: pieces of broken rocks, shells, mineral grains, and other material
Processes:
Compaction-pressure from the upper layers
Cementation-sediment that is glued together

11. Video Clip Metamorphic Rock

12. Granite becomes gneiss
Metamorphic Rock
Note Taker #3!
Illustrator!
Metamorphic rock:
Rocks that “change” their form; the process of making new rocks out of old ones.
Metamorphic rocks are formed below Earth’s surface where the rock is subject to extreme pressure and heat…chemical change.
Some examples of how metamorphic rocks were changed:
Granite becomes gneiss
