Geology review

What kind of rock is formed by the compaction and cementation of sediments

• Igneous Rocks

• Metamorphic Rocks

• Sedimentary Rocks

• Crystals

Can igneous rocks contain air bubbles?

• True

• False

Rocks are classified by:

• where you find them

• their density

• their mass

• how they form

The three rock types are:

• Metamorphic, crystalline and magma

• Intrusive, extrusive and globular

• Igneous, sedimentary and metamorphic

Which of the following has the greatest erosional power?

• an avalanche

• creep

• a landslide

• glacier

Which is the correct?

• Layer R is younger than layers B, J, and F

• Intrusion R is older than layers X, S and M

• Intrusion R is older than B, but younger than X

• Layer B is older than older than X but younger than R

Which TWO statement about earthquakes are true?

• Earthquakes have only occurred in the distant past.

• When plates shift, earthquakes sometimes happen.

• Continental movement is evidence that plates have shifted, resulting in earthquakes, since the beginning of time, and will likely continue forever.

• Earthquakes are always caused by volcanic eruptions that caused the continents to break apart. Continents will definitely never all be connected again.

Which statement is true of the Law of Superposition?

• In undisturbed rock layers, the bottom layers are the oldest.

• In undisturbed rock layers, the bottom layers are the youngest.

• In disturbed rock layers, broken layers are always the youngest.

• In disturbed rock layers, the top layers are always the oldest.

Why is the study of ice cores important to the study of geologic history?

• It allows scientists to determine the age of Earth.

• It allows scientists to determine the number of species that have gone extinct.

• It allows scientists to determine the pattern of large mammal migration.

• It allows scientists to determine how and why climate changed in the past.

Which can most likely be concluded about the area where the samples were found?

• The area has shrunk over time.

• The area was once under water.

• Organisms in layers 1 and 2 became extinct miles away.

• The area did not support any life.
