2. This Presentation Will Cover:
Rocks: Igneous, Metamorphic, and Sedimentary
Fossils: What they are, how are they formed?
Natural Resources: Non-renewable and Renewable .
This presentation will test your understanding of our Earth Science Unit.
Answer the questions to the best of your ability. Each page has a forward and back arrow.
Good luck!

3. Igneous Rock Sedimentary Rock Metamorphic Rock
I take many years to form. I am created when layers of dirt, sand, and shells are compacted together. What am I?
Igneous Rock
Sedimentary Rock
Metamorphic Rock

4. GREAT JOB! Sedimentary Rocks.
GREAT JOB!
Sedimentary rocks are formed where there is, or was water. They are soft, layered, and often contain many fossils. Examples include: limestone, sandstone, chalk, and shale.

5. Metamorphic Rock Igneous Rock Sedimentary Rock
I am created when lava from inside the Earth is pushed through the Earth’s crust and hardens. What am I?
Metamorphic Rock
Igneous Rock
Sedimentary Rock

6. Nice Job! Igneous Rocks Igneous Rocks Include: Pumice Basalt Obsidian
Igneous Rocks are usually glossy or coarse, and full of holes.
They are formed where there are (or have been) volcanoes.
Igneous Rocks Include:
Pumice
Basalt
Obsidian
Nice Job!

7. I once was a sedimentary or igneous rock, but heat, pressure, or water caused a change, and now I am something else entirely. What am I?
Sedimentary Rock
Igneous Rock
Metamorphic Rock

8. Metamorphic Rocks Metamorphic rocks include: Geodes Marble Slate
Metamorphic rocks are created deep within the Earth, through a combination of heat, pressure, or water. They sometimes have layers like sedimentary rocks, but they are very hard. They may also contain crystals.
Metamorphic rocks include:
Geodes
Marble
Slate

9. Metamorphic Rocks
Metamorphic rocks were once sedimentary or igneous rocks that have undergone a change due to heat, pressure, or water. Below are some examples:
Quartzite
becomes
Sandstone
Slate
becomes
Shale
Marble
becomes
Limestone

10. What is a fossil? Fossils
Fossils are the remains or evidence of creatures that once lived on Earth.

11. How many types of fossils are there?
One
Two
Three

12. There are two types of fossils:
Type One is made from the remains of the animal or plant, or the imprint that was left behind.
Bones
Hair
Teeth
Shells of ancient invertebrates
Impressions of plants

13. There are two types of fossils:
Type Two are called Trace Fossils. They were made while the animal was living, and they hardened into stone.
Footprints
Burrows
Coprolite (animal poop)

14. What are the types of naturally occurring resources available to us?
Natural Resources & Unnatural Resources
Renewable Resources & Non-renewable Resources
Old Resources & New Resources

15. Renewable & Non-Renewable Resources
Renewable Resources are continually available, they replace themselves faster than we use them.
Non-Renewable Resources are limited in supply. Once they are gone, they are gone forever.

16. Examples of Resources Renewable Resource Non-Renewable Resource Water
Coal
Oxygen
Crude Oil
Plants
Copper
Animals
Silver
Timber
Iron
Cotton
Gold

17. Water Cycle Cloud Formation Precipitation Surface Run-off and Rivers
Ocean
Evaporation
Condensing Water Vapor

18. Review: Today we learned about:
Rocks
Igneous: formed by cooling magma.
Metamorphic: rocks that have been changed by heat or pressure.
Sedimentary: formed by layers of dirt and sand accumulating
Fossils
Fossils are remains of animals or plants or evidence
that they were here, such as footprints.
Natural Resources
Renewable Resources recreate themselves faster than we use them.
Nonrenewable Resources have a limited supply.

19. Oops! Better Luck Next Time!

20. So Close….
Time for a second try!

21. Almost There! Try Again!
