Rocks and Minerals

The five characteristics that all minerals share are:

• Definite Chemical Composition, Color, Density, Igneous, and Solid
• Definite Chemical Composition,  Crystal Structure, Inorganic, Naturally Occurring, and Solid
• Cleavage, Faces, Hardness, Metamorphic, and Streak
• Cleavage, Crystal Structure, Density, Igneous, and Solid

This is measured on  the Mohs Scale.

• Cleavage
• Density
• Hardness
• Luster

_______ is found by rubbing the mineral against an unglazed tile called a plate.

• Cleavage
• Color
• Luster
• Streak

_______ is a property that describes a mineral  that splits evenly along flat surfaces.

• Cleavage
• Fracture
• Inorganic
• Organic

This describes how a mineral looks if it breaks in an irregular way.

• Cleavage
• Fracture
• Inorganic
• Organic

The three major rock groups are:

• Inorganic, Metamorphic, and  Sedimentary
• Inorganic, Metamorphosis, and Sediment
• Igneous, Metamorphic, and Sediment
• Igneous, Metamorphic, and Sedimentary

This rock  is formed from molten rock (magma/lava) that has cooled.

• Igneous
• Inorganic
• Metamorphic
• Sedimentary

This rock is formed by erosion (continuously broken down into small fragments) and  then is compressed and  cemented together.

• Inorganic
• Igneous
• Metamorphic
• Sedimentary

This rock is formed by extreme heat and/or pressure that alters the chemical composition into a new form of rock.

• Inorganic
• Igneous
• Metamorphic
• Sedimentary

When identifying minerals, _______ can be tested by scratching the surface with different materials such as your fingernail or a coin.

• Cleavage
• Density
• Hardness
• Streak
