What’s the Difference?

Rock vs. Mineral
Rocksolid mineral material that makes up
the solid surface of the Earth
MineralNaturally occurring inorganic solid

Rocks “the solid material forming the Earth”
Sedimentary Igneous Metamorphic
![Page 7: Miss Napolitano 3 rd grade Science. Earth Science The branch of science dealing with the constitution of the earth and its atmosphere](https://reader035.vdocument.in/reader035/viewer/2022062806/56649cbf5503460f94985871/html5/thumbnails/7.jpg)
• Forms when molten, or melted, Earth Rocks cool and harden
• A very hot mixture of melted minerals and gases
• Different kinds of igneous rock can form depending on how quickly or how slowly the rocks melt
• Usually found near volcanoes or hot underwater vents
• Dark and smooth or rough with many different colors
• On location with Igneous Rock
Igneous
Granite

• Morph: means change in form
• Forms when great heat or pressure inside the Earth change an existing rock into a new form
Metamorphic
Marble

• Sediment: tiny bits of rock, sand, shells, and other materials
• Formed in locations near water at one point in time
• Made of small pieces of rocks or sediment
• When these different materials are pressed or
cemented together, sedimentary rock forms
• Type of rock in which fossils are found
Sedimentary

Fossils Found in Sedimentary Rock Fossils: Remains left by plants and animals that lived long ago. They were buried in mud or sand that hardened into rock over millions of years. Fossils are only found in sedimentary rocks.

Characteristics of Minerals• Made from natural, nonliving materials• Cover all of Earth’s surface• Also found inside our bodies• Stable at room temperature• Approx 4,000 known minerals• 100 are common

MINI MINERALOGISTS!
Open the mineral kit and chose 1 mineralLets pretend to be mineralogists and complete
tests to figure out what mineral we have!
1. Color
2. Hardness
3. Luster
4. Special Properties
![Page 17: Miss Napolitano 3 rd grade Science. Earth Science The branch of science dealing with the constitution of the earth and its atmosphere](https://reader035.vdocument.in/reader035/viewer/2022062806/56649cbf5503460f94985871/html5/thumbnails/17.jpg)
Mineral Characteristics • Color – Use specific names to describe the color• Hardness – What happens when the mineral is
scratched with your fingernail? A penny? A nail?• Luster – How shiny is your mineral? When you use
a flashlight, what does it look like? • Special Properties – Is it magnetic? We use these four things to put minerals into groups, or categories.
