Earth History Review

Carbon-14 is involved in which type of dating?

• absolute

• igneous

• metamorphic

• relative

Which best describes how ice cores are important to the study of geologic history?

• They show unconformities, which signal changes in deposition.

• They hold index fossils, which are used to date the different ice cores.

• They contain evidence showing changes in the atmospheric pressure over time.

• They follow the law of Superposition, which gives reasons for extinctions of species.

In which way can scientists best use ice cores to reconstruct Earth's climate history?

• By studying the location and depth of the ice.

• By studying the composition of the frozen water.

• By studying the atmospheric gases trapped in the ice.

A fossil discovered in Colorado dates from early Mesozoic era. A year later a similar fossil is found in Wyoming that also dates from the early Mesozoic era. These two organisms most likely lived in:

• The same environment at about the same time.

• The same environment at different times.

• Different environments at about the same time.

• Different environments at different times.

A student is visiting a local limestone quarry and finds fossils of seashells. The quarry is located hundreds of miles from the ocean. The fossils BEST indicate that:

• This area was once below sea level.

• Global temperature changed over time.

• Erosion took place after a flood.

• Volcanic activity affected the area.

Which statement BEST describes the Law of Superposition?

• Each sedimentary layer of rock represents 1,000 years of Earth's age, much like the rings of a tree.

• In undisturbed layers of sedimentary rock, the upper rock layers are older than the lower rock layer.

• In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.

• Rocks that form near volcanoes are older than surrounding rock.
