What are rocks made of? minerals

Minerals are not made by people; they are … … naturally occurring substances.

Name four properties (or clues) that scientists use to identify minerals. Color, luster, streak, and hardness

Property of mineral: color ,[object Object],[object Object],[object Object]

Sometimes the color can help you figure out what it is, other times it can fool you. ,[object Object]

Did you guess? As you can see… ,[object Object],[object Object]

Which property means the way the light bounces off the mineral? luster

What words can be used to describe a mineral’s luster? Glassy, dull, shiny, greasy

Property of mineral: streak ,[object Object]

Property of mineral: hardness ,[object Object]

What are three testers that can be used to determine a mineral’s hardness? fingernail, penny, nail

TYPES OF ROCKS Classified by how they Are formed. IGNEOUS ROCKS (melted rock from inside The Earth cools) SEDIMENTARY (sediment collects in Layers that form rocks) METAMORPHIC (rocks form from Pressure and temp) EXTRUSIVE Melted rock cools Melted rock that reaches The surface is called lava. INTRUSIVE Magma forced up but Doesn’t reach surface Magma—melted rock that Doesn’t reach the earth.

Sedimentary rocks form in 3 ways: ,[object Object],Made up of grains of minerals or other rocks. The weight of the sediments squeezes them into layers.

Sedimentary rocks form in 3 ways: ,[object Object]

Sedimentary rocks form in 3 ways: ,[object Object],Seawater filled with minerals evaporates. As water evaporates, layers of minerals are left behind.

Types of Sedimentary Rock ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

The breaking down and wearing away of rocks is called… weathering.

The movement of sediments from one place to another is called… erosion.
