1. Rocks and Minerals
Lets Rock!

2. Engage Is it a Rock (Version 2)
Have the students so this on their own and then as a table
Make copies and glue in notebooks

3. Explore Journal- List what you know about Rocks and Rock cycle
Brain pop- Rock Cycle and Types of Rock
Assign notes and vocab

4. Explain- The Earth’s crust is made up of 2 things:
Minerals and Rocks
Coal
Gneiss
Scoria
Rocks are
combinations
of minerals
Minerals are
individual crystals
of all the same stuff
***You should see lots of different
minerals in every single rock

5. Minerals are….. Naturally occurring Nonliving
Have specific chemical formula
Quartz : SiO
Emerald: Be3Al2Si6O18

6. In 2008, crystals up to 39 feet long were found in a cave in Mexico at a depth of 1000 feet.
The cave is extremely hot, with air temperatures reaching 136 °F with 90 to 99 % humidity.

7. There are 3 Types of Rocks

8. Three Types of Rocks Rocks are classified by how they form Igneous
Sedimentary
Metamorphic
Rocks can change from one type to another over time
Schist

9. Rock Classification Rocks are classified by: How they form Texture
Grain size
Mineral composition
Conglomerate Sedimentary Rock

10. Igneous Rock
Igneous rocks are formed by magma and lava as it cools. Igneous rocks form in two different ways.
Rock that comes from lava cools very fast and can either be very light and airy or the rocks can be glassy.
Rocks that come from magma are formed under ground. They are often times very hard and have more colors.

11. Intrusive Igneous Rock
Intrusive igneous: cooling takes place slowly beneath Earth’s surface
granite

12. Extrusive Igneous Rock
Extrusive igneous: cooling takes place rapidly on Earth’s surface
Pumice

13. Igneous rock

14. Sedimentary Rock
Sedimentary rock: forms from the compaction and/or cementation of sediments
This process is called lithification
Sediments are:
Rock pieces
Mineral grains
Shell fragments
Limestone

15. How do sediments form?
weathering
Sediments form through the processes of weathering and erosion of rocks exposed at Earth’s surface
erosion

16. Sedimentary Rock con’t….
Sedimentary rock can also form from the chemical depositing of materials that were once dissolved in water
When water evaporates, minerals are left behind and form rock
gypsum

17. Sedimentary Rock
Sedimentary rock is made when sediments (sand, gravel, and dirt) are pressed together over time and become a rock
Sedimentary rock is formed in layers.

18. Sedimentary Rocks
Limestone
Shale
Sandstone
Granite

19. Metamorphic Rock
Metamorphic rock: forms when any rock type is changed into a different kind of rock
Changes due to great heat and/or pressure
Gneiss

20. How does rock change?
Rocks are heated, squeezed, folded, or chemically changed by contact with hot fluids
marble

21. Metamorphic Rock Metamorphic rocks are made from other rocks.
Heat and pressure help change an igneous or sedimentary rock into a new kind of rock (think about how a caterpillar becomes a butterfly)

22. The Rock Cycle

23. The Earth Recycles Rock
The rock cycle is an ongoing series of processes inside Earth and on the surface
Slowly changes rocks from one kind to another
Any type of rock can change into another type

24. How does this relate to plate tectonics?
Plate movement drives the rock cycle
Subduction (1 plate pushed under another plate)
Re-melts rock into magma
Mountain building
Folding, faulting, uplift
Exposes rock at the surface to be weathered and eroded

27. This is made of individual crystals
A. Rocks B. Minerals C. Cement D. Paper

28. This is made up of minerals
A. Rocks B. Minerals C. Cement D. Paper

29. This type of rock is formed by lava cooling.
A. Sedimentary Rock B. Igneous Rock C. Metamorphic Rock

30. This type of rock is formed by another type of rock changing forms.
A. Sedimentary Rock B. Igneous Rock C. Metamorphic Rock

31. This type of rock is formed with sediments are pressed together
A. Sedimentary Rock B. Igneous Rock C. Metamorphic Rock
