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.

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

Where are ROCKs? Rocks are everywhere! Like…

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 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

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

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

Video Clip Metamorphic Rock https://www.youtube.com/watch?v=-MSK3n5uNvg

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

Checks for understanding! A rock is a solid material that is usually made up of two or more ____________. An ___________ rock is one that has been formed from magma. The two types of igneous rocks are ______________ and ______________. What is sediment? 5. What are the two processes that are needed for sedimentary rock to form? ______________ and ____________. 6. What does “metamorphic” mean? 7. What two processes are needed for metamorphic rock to form?
