ROCKS

3.1 The Rock Cycle

Rocks are solids made of one or more minerals There are three types of rocks:

1. Igneous 2. Sedimentary 3. Metamorphic

Together they made up the study of GEOLOGY

How do these connect to Earth and Space Science?

BIG IDEA

They occupy 5/6 of the Earth’s Volume They make up 2/3 of the Earth’s Mass

The oldest rocks are meteorites They are 4.5 billion years old

SPACE AND TIME

The three types of rocks are

INTERCONNECTED through the ROCK CYCLE

FORCES AND MOTION

The appearance of a rock is affected by several

factors: What elements it’s made from Rate of cooling They way it’s compacted Amount of Heat and Pressure Exposure to types of hot fluids

Matter and Energy

Rocks are like TIME MACHINES! By analyzing their characteristics we can learn

about conditions that existed on Earth long ago.

Rocks are so cool they make it into famous movies!

Find a cool rock from anywhere in the world1. Write the name2. Where in the world it is3. Include a picture4. What include the type of rock it is (igneous,

sedimentary, or metamorphic)

3.1 The Rock Cycle

A rock is a solid mass of mineral or mineral-

like matter that occurs naturally as part of our planet

Three types of rock are:1.2.3.

Definition

When the systems interact, they cause rocks to

change from one type to another. This is called the Rock Cycle

Video and Worksheet

Using the textbook (pg. 67) re-create the rock cycle

Show all the connections that can be made from one part of the rock cycle to the other

When finished, answer this question:

Question: Can a sedimentary rock become an igneous rock without changing first to a metamorphic rock? Explain

Putting the Rock Cycle Together

1. What enables rocks to take alternate paths 2. Where does the energy that powers The

Rock Cycle come from?

ePortfolio work: 1. Upload your image of the Rock Cycle 2. Two questions from 3.1

Exceeding Questions

1. What are the three types of rocks?

2. Place the rocks in the correct order in the rock cycle

3. What are the two types of Igneous Rocks?

3.1 Review

Goals for the class:

1. Compare Extrusive and Intrusive Igneous Rocks 2. Demonstrate how the rate of cooling affects and

igneous rock’s texture 3. Classify Igneous rocks according to texture and

composition

3.2 Igneous Rocks

Example:

Goal 1: Comparing Igneous Rocks

• Page 71 of the Textbook• Read about Intrusive and Extrusive Igneous Rocks and complete

The table. Use the heading as a guide.

As Magma rises from the depths underground, it cools As it cools, elements combine and form minerals These minerals grow in size and become a solid mass of

interlocking crystals.

Goal 2: Rate of cooling in Igneous Rocks

EXTRUSIVE INTRUSIVE

Extrusive and Intrusive Igneous rocks have

different appearances. How can we group them?

at: Texture (what it feels like) Composition (what it’s made from)

Textures: Coarse-grained, fine-grained, glassy, porphyritic

Compositions: Granitic, Basaltic, Andesitic, Ultramafic

Goal 3: Classification

Use the table provided to describe the different

textures and compositions
