Rocks and Minerals

Types of Rock Metamorphic rock form with extreme heat and pressure over time. Examples of metamorphic rocks are marble, quartz and slate.Sedimentary rocks are formed when sediment deposits over time often as layers at the bottom of lakes and oceans. Examples of sedimentary rocks are sandstone, mudstone and flint. Igneous rocks are formed when magma cools and solidifies. Examples of igneous rocks are granite, basalt, and pumice. ...................................................................................................................................................................................................................................................................................................................................................................................................................

Important notes:*All rocks are made of 2 or more minerals, but minerals are not made of rocks. *Types of Rocks: Igneous, Metamorphic and Sedimentary*Rocks are constantly being formed, worn down and then formed again. This is known as the Rock Cycle.*Minerals are the same all the way through. *There are about 3000 known minerals on earth. *All rocks are made up of 2 or more of these minerals.

Sedimentary Rock

A mineral is composed of the same substance throughout. If you were to cut a mineral sample, it would look the same throughout. There are about 3000 different minerals in the world.Minerals are made up of chemicals-either a single chemical or a combination of chemicals.Examples of minerals are quartz, calcite, feldspar, mica and hornblend.quartz-silicon+qxygen tetrahedracalcite-carbonite mineral (CaCO3)mica-silicate mineralshornblende-inosilicate mineral
