A geologist identifies the identical index fossils in rock layers from two different areas. Which conclusion is best supported by this discovery?

• The deposition rate of the two rock layers was identical.

• The fossil organism evolved independently in the two separate areas.

• The two rock layers were deposited at approximately the same time.

• The index fossil will also occur in sediment deposited on top of these rock layers.

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 layers.

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

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

The relative age of a rock is

• The number of years since the rock formed

• Less than the age of the fossils the rock contains

• Its age based on how much carbon-14 the rock contains

• Its age compared with the ages of rock layers around it

Four sedimentary rock layers, a fault, and an igneous rock intrusion are shown below.

• The fault is younger than the igneous rock intursion and the four sedimentary rock layers.

• The fault is older than the igneous rock intrusion and the four sedimentary rock layers.

• The fault is younger than the igneous rock intrusion and older than the four sedimentary rock layers.

• The fault is older than the igneous rock intrusion and younger than the four sedimentary rock layers

Which explanation best describes why marine fossils have been discovered in rock layers in a desert environment?

• A catastrophic event occurred in the area in the past.
• Continental drift moved the rock layers from the coast to the desert.
