ICP Ch. 23 Review Part 3 (RAT)

The silicates are the largest mineral group because silicon and oxygen are 

• the hardest elements on Earth's surface.
• the two most abundant elements on Earth's surface.
• found in the common mineral quartz.

What physical change in metamorphic rock signals the end of metamorphism?

• freezing
• melting
• crystallization
• evaporation

Wow! You find a rock that contains a fossil. The rock could be 

• diamond.
• limestone.
• marble.
• basalt.

Which of these does not belong in your mineral collection?

• table salt
• diamond
• quartz
• coal

Igneous rocks are the most common of the three types of rocks. Yet they are not often observed because they are typically buried under

• metamorphic rock.
• sedimentary rock.
• minerals.

Large crystals are usually associated with 

• intrusive igneous rocks.
• metamorphic rocks.
• extrusive igneous rocks.
• minerals.

During the early stages of Earth's development, when the entire planet was molten, there were no rocks. What kind of rocks must have been the first to form?

• igneous rocks
• sedimentary rocks
• metamorphic rocks

Magma transfers heat to the surround rock as it rises toward Earth's surface. The rocks that absorb this heat may undergo 

• compaction.
• regional metamorphism.
• contact metamorphism. 
• cleavage

Conglomerate is a sedimentary rock that consists of large, rounded pieces of other rocks embedded in mineral "cement". What type of sedimentary rock is conglomerate?

• foliated
• chemical
• clastic
• extrusive

An igneous rock can be transformed into a metamorphic rock by 

• weathering, erosion, deposition, then compaction to become a sedimentary rock, then heat and pressure.
• being squeezed by great tectonic forces such as occur at a convergent plate boundary.
• being heated by magma flowing nearby.
• all of these.
