Rocks and Minerals Study Guide

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

Coal is a sedimentary rock formed

through

• the cooling of magma, brought to the

  surface through fissures.

• compaction of limestone, where

  interlocking crystals form underground.

• Coal is a sedimentary rock formed

  through

• buried organic debris, compressed and

  heated, leaving carbon behind.

A student analyzing an unknown rock

that formed on Earth's surface observes

that the rock has no layers, no individual

particles or crystal grains, and is smooth

and glassy. The unknown rock is most

likely classified as

• intrusive igneous rock.

• extrusive igneous rock.

• intrusive metamorphic rock.

• extrusive metamorphic rock.

The processes responsible for changing

sediments into sedimentary rock are

compaction and

• intrusion.

• cementation.

• stratification.

• foliation.

Which of the following properties of

minerals is described with the Mohs

scale?

• hardness

• luster

• fluorescence

• fracture

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

Which is NOT a property of rocks and

minerals that can be discovered by

looking at them?

• texture

• weight

• color

• luster

How are elements, rocks, and minerals

related?

• Minerals are made of elements and

  elements are made of rocks.

• Elements are made of rocks and rocks

  are made of minerals.

• Rocks are made of minerals, and

  minerals are made of elements.

• Minerals are made of rocks, and rocks

  are made of elements.

The process in which existing minerals

are changed into new minerals due to

the influence of extreme pressure or

temperature is called

• deposition

• evaporation

• metamorphosis

• crystallization
