ES - Minerals lesson 2

Physical Properties

Vocabulary

• Rock - a naturally occurring mixture of one or more minerals.

• Mineral - a naturally occurring, inorganic solid that has a crystalline structure.

• Weathering - process of rock being broken down into smaller pieces.

Vocabulary

• Erosion - movement of sediment from one place to another.

• Deposition - the placement of sediment moved by erosion.

• Rock Cycle - the continual process that forms new rock from old rock.

Vocabulary

• Sedimentary rock - surface rock formed by compressed sediment.

• Metamorphic rock - rock formed from other rock by intense heat and pressure.

• Igneous rock - rock formed when magma cools and hardens.

Rocks and Minerals

Rocks and minerals are closely related, but are not two words for the same thing. A rock is a naturally r mixture of one or more minerals. They also may or may not contain organic matter. A mineral is a naturally occurring, inorganic solid that has a crystalline structure.
