The diagram below represents several sedimentary layers of Earth’s crust after erosion from a river has exposed some of the lower layers. 
Which would be the most significant benefit to a scientist studying Earth’s past at this location?

• Scientists would be able to determine that volcanic activity was present during the time of the oldest exposed sediment layer.
• Scientists would be able to determine if the rocks were metamorphic or igneous.
• Scientists would be able to determine if there was water at this location.
• Scientists would be able to look at fossilized remains of past life dating back to the oldest exposed layer of sediment.

The diagram below shows a stack of rock layers.  
Layer R contains a well-known index fossil that is 100 million years old. Based on this information and the law of superposition, you can make the following claim.

• Layers T and M are younger than 100 million years.Layers X and G are older than 100 million years.
• Layers T, M, X, and G are all younger than 100 million years.
• Layers T, M, X, and G are all older than 100 million years.
• Layers T and M are older than 100 million years.Layers X and G are younger than 100 million years.

Two fossils that appear to be from the same type of organism are found in two different layers of rock. The layers of rock are shown below.

Which can be determined from the location of the fossils?

• The prey of organisms

• The predators of the organism

• The cause of death for each organism

• The relative age of each organism

An archaeologist made the following diagram of a dig site. What can be said about the pottery as compared to the skull found in the site?

• The rock layer with the pottery is more recent than the rock layer with the skull.
• The rock layer with the skull is more recent than the rock layer with the pottery.
• The rock layer with the skull is approximately the same age as the rock layer with the pottery.
• The rock layer with the skull has an absolute date of 17,000 years.
