Rocks and Minerals

As igneous rocks become more mafic,

• the color becomes lighter

• the color becomes darker

• the density gets lighter

• the texture becomes fine

Igneous rocks are also known as

• Clastic

  Bioclastic

  Crystalline

• Extrusive

  Intrusive

• Foliated

  Non-foliated

• Metallic

  Nonmetallic

Clastic sedimentary rocks are also called

• Crystalline

• Bioclastic

• Extrusive

• Fragmental

Metamorphic Rocks are formed through the process of

• Deposition and Burial

• Heat and Pressure

• Weathering and Erosion

• Melting and Solidification

Minerals can be classified through

• Composition

  Texture

  Crystal Size

• Texture

  Grain Size

  Composition

• Luster

  Hardness

  Streak

• Luster

  Color

  Composition

Most igneous rocks are formed by which process

• Erosion and Deposition

• Heat and Pressure

• Melting and Solidification

• Compaction and Cementation

The best evidence for determining cooling rate of an igneous rock during its solidification is provided by

• the mineral composition

• the crystal size of its minerals

• the index fossils

• faults in the rock

The physical properties of minerals are determined by

• their streak and color

• their luster and hardness

• the internal arrangement of their atoms

• their composition
