Rocks

Foliated rocks are distinguished by

• layers

• lack of layers

• large mineral grains

• air holes

All the following conditions in Earth can cause metamorphic rocks to form EXCEPT

• exposure to air

• the presence of hot, water fluids

• heat

• pressure

Different types of metamorphic rocks are distinguished by the:

• chemical make-up of the rock

• location in which the rock was found

• location of the rock formation

• arrangement of mineral grains within the rock

A kind of non-foliated metamorphic rock

• coal

• marble

• limestone

• slate

A kind of chemical sedimentary rock

• limestone

• coal

• compaction

• cementation

Sedimentary rocks are ___

• formed from magma

• a type of foliated igneous rock

• formed because of changes in temperature and pressure, or the presence of hot watery fluids

• formed when loose materials become pressed or cemented together or when minerals form from solutions

Sedimentary rocks form because of all of the following EXCEPT ___

• sediments becoming pressed or cemented together

• crystals solidifying from magma

• sediments forming from solution

• water evaporating, leaving crystals behind

Rocks formed by changes in heat and pressure or the presence of hot, watery fluids

• foliated

• Igneous Rocks
