What’s the Difference?
Rock vs. Mineral Rock Mineral solid mineral material that makes up the solid surface of the Earth Mineral Naturally occurring inorganic solid
“the solid material forming the Earth” Rocks “the solid material forming the Earth” Sedimentary Igneous Metamorphic
Igneous 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 Ecuadorian volcano eruption Syracuse Lava experiment Volcanic lava flow Granite
Metamorphic Morph: means change in form Forms when great heat or pressure inside the Earth change an existing rock into a new form Marble
Sedimentary 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
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.
Locations of the 3 Rock Types Check out these videos about how rock types are formed!
Rock Formation The Rock Cycle
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 Brain Pop Mineral Identification
Mineral Identification Color Mohs Scale Density How it splits How it breaks Shininess Crushed color Magnetic, Acid sensitive Color Hardness Specific Gravity Cleavage Fracture Luster Streak Special Properties
Mini Mineralogists! Open the mineral kit and chose 1 mineral Lets pretend to be mineralogists and complete tests to figure out what mineral we have! Color Hardness Luster Special Properties
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.
Luster Vocab Metallic: very high reflectance, opaque Submetallic: medium reflectance, opaque Adamantine: very high reflectance, transparent Glassy: high reflectance, transparent or translucent Resinous: medium reflectance, translucent Waxy: medium reflectance, translucent or opaque Pearly: low reflectance, translucent or opaque Dull: no reflectance, opaque
What is Soil, really? Layers of Soil
