Warm-Up Did anyone ever have a rock collection?

Where do you think these rocks came from?

Do these rocks last forever?

THE ROCK CYCLEEarth Science

The Rock Cycle

Rock Cycle – A series of processes that transform material from the stages of magma, igneous rock, sediment, sedimentary rock, or metamorphic rock to another

Critical Thinking #1 How does a “cycle” work? What does this

tell us about the history of a specific type of rock?

Rock Types There are three main types of rock based

on how each type formed Igneous Sedimentary Metamorphic

Igneous Rocks Igneous Rocks – Rock formed by the

cooling and crystallization of magma

Critical Thinking #2 Based on how igneous rocks form, describe

one scenario where igneous rocks are produced.

Sedimentary Rock Sedimentary Rock - Rock formed by the

cementation and compaction of sediments

Critical Thinking #3 Based on how sedimentary rocks form,

describe one scenario where sedimentary rocks are produced.

Metamorphic Rock Metamorphic Rock – Rocks which undergo

physical or chemical changes due to extreme heat and pressure

Critical Thinking #4 Based on how metamorphic rocks form,

describe one scenario where metamorphic rock are produced.

Steps of the Rock Cycle 1. Magma – Cools and “Crystalizes” into

Igneous Rock 2. Igneous Rock – Undergoes Weathering

and Erosion to turn into Sediment 3. Sediment – Is Compacted and

Cemented into Sedimentary Rock

Steps of the Rock Cycle 4. Sedimentary Rock – Undergoes

tremendous Heat and Pressure to turn into Metamorphic Rock

5. Metamorphic Rock – Melts into Magma

Critical Thinking #5 Based on how each type of rock or material

is transformed into another, is it possible for the cycle to go out of the aforementioned order?
