What type of rock is pictured?

• Igneous
• Metamorphic
• Sedimentary

Gneiss is a rock because it

• is hard and round.
• has crystals.
• is made of minerals.
• has mass.

The following contains the properties of four different samples:

Sample W is hard and composed of two materials

Sample X is soft and composed of one material

Sample Y is hard and composed of one material

Sample Z is hard and composed of three materials

Which of the following is true of the objects?

• Samples X and Z are minerals, and

  samples W and Y are rocks

• Samples X and Y are minerals, and

  samples W and Z are rocks.

• Samples W and Z are minerals, and

  samples X and Y are rocks.

• Samples W and Y are minerals, and

  samples X and Z are rocks.

Which of the following is NOT a property

of minerals?

• luster

• fracture

• color

• ore

The processes responsible for changing

sediments into sedimentary rock are

compaction and

• intrusion.

• cementation.

• stratification.

• foliation.

An unknown rock sample, X, formed from

weathering, erosion, and compaction.

Unknown rock sample X is.....

• a metamorphic rock

• a sedimentary rock

• an extrusive igneus rock

• an intrusive igneus rock

Metamorphic rock is formed by

• compacting and cementing

• melting and cooling

• heat and pressure

• erosion and weathering

Limestone is a type of rock that can form in two

ways. It can either form from the accumulation of

shell and skeletal debris of ocean organisms, or it

can form when calcium compounds precipitate

out of ocean water and become cemented

together. Under which classification does

limestone belong?

• igneous rock

• silica rock

• metamorphic rock

• sedimentary rock
