Rocks, Minerals and Ores

In the rock cycle, what happens to a metamorphic rock deep in the Earth's crust when it is exposed to extreme heat and pressure

• it cools to form an igneous rock

• compaction/cementation to form a sedimentary rock

• melts into magma

• it breaks down into sediments

How are ROCKS classified?

• By how they look

• By how they feel

• By how they form

• By how they smell

Minerals that are mined because they contain useful metals or nonmetals are called

• rocks
• fossil fuels
• chemicals
• ores

An igneous rock is found with large crystals.  What kind of rock is it?

• clastic
• foliated
• intrusive
• extrusive

Deposits of minerals from which metals and nonmetals can be removed profitably.

• Ore
• Conduction
• Placer Deposits
• Wire

Forms from the compaction and/or cementation of rock pieces, mineral grains, or shell fragments.

• Igneous
• Metamorphic
• Sedimentary

Some igneous rock are called extrusive because

• cooling takes place slowly beneath Earth’s surface
• cooling takes place slowly on Earth’s surface
• cooling takes place rapidly on Earth’s surface
• cooling takes place rapidly below Earth’s surface

Which layer of soil is on bottom?

• Topsoil

• Sand

• Bedrock

• Aggregate

Are fossil fuels renewable resources or non-renewable resources? 

• Renewable
• Non-Renewable

What the name of a rock with a lot of minerals?

• Ore
• Zinc
• Cobalt
• Platinum
