Sths Is9 Rocks And Minerals

Front 1

Minerals

Back 1

Naturally occurring, inorganic solids, definite chemical composition, orderly atomic structure

Front 2

Igneous Rocks

Back 2

Formed from melted minerals

Front 3

Sedimentary Rocks

Back 3

Rocks formed from pieces of other rocks, from once living things, or from solutions

Front 4

Metamorphic Rocks

Back 4

Rocks formed from great heat and pressure

Front 5

The Rock Cycle

Back 5

The process of rocks changing from one rock type to another

Front 6

Biogeochemical Cycles

Back 6

The cycling of an element or a compound through the environment

Front 7

Crystal Form

Back 7

Regular, repeating arrangement of atoms, like halite which forms a cubic shape

Front 8

Luster

Back 8

Looks like metal, like pyrite which looks like gold, or galena which looks like a silvery metal

Front 9

Hardness

Back 9

The strength of the chemical bonds, defined as the minerals resistance to scratching glass

Front 10

Mohs Hardness Scale

Back 10

1-10, 1 is the softest like talc, and 10 is the hardest like diamond

Front 11

Cleavage

Back 11

When a mineral breaks along parallel lines like Mica ,which peels in layers, or when a mineral breaks into specific shapes like halite which breaks into cubes

Front 12

Streak

Back 12

When a mineral is scraped along an unglazed porcelain tile and a powder is left behind on the tile. The powder is the streak of the mineral which is more reliable than the color of the mineral when used for identifying minerals

Front 13

Slow Cooling

Back 13

Allows for large crystals to form in igneous rocks like granite

Front 14

Fast Cooling

Back 14

Allows only small crystals to form in igneous rocks like basalt

Front 15

Extra Fast Cooling

Back 15

No crystals form at all in an igneous rock like obsidian or pumice

Front 16

Melting and Cooling

Back 16

The processes that help form igneous rocks

Front 17

Great Heat and Great Pressure

Back 17

The processes that help form metamorphic rocks

Front 18

Weathering and Erosion

Back 18

The processes that help form sedimentary rocks
