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!

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

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.

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

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!

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

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

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

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

How many types of fossils are there? One Two Three

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

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)

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

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.

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

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

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.

Oops! Better Luck Next Time!

So Close…. Time for a second try!

Almost There! Try Again!
