Rocks Strata and Earth History

The illustration provided shows three rock layers and an intrusion of basalt. When molten rock pushes its way into rock layers already formed, it creates an intrusion. The rock strata indicate that the basaltic intrusion must have occurred-

• After the limestone was deposited

• Before granite was formed

• Before limestone was deposited

• Before three layers were formed

The diagram here provides information on when the fossils of certain organisms are found in the fossil record. Which of the following conclusions can be drawn from the data in this diagram?

• Jellyfish and trilobites never competed for resources.

• Trilobites and dinosaurs did not live at the same time.

• Most mammals are in competition with birds for resources.

• Mammals did not appear until after the dinosaurs went extinct.

The fossil remains of organisms with skeletons are not found in the lowest layers of rock discovered. How is the lack of fossilized skeletons in the lowest rock layers best explained?

• Organisms with skeletons did not evolve until after these rock layers formed.

• The fossils of organisms with skeletons are only found in the oldest rocks.

• Fossil skeletons are usually crushed if other rock layers are above the ones they are in.

• Organisms with skeletons live only at the highest altitudes, which is where they turn to fossils.

The illustration here shows rock layers in their original order, along with a fracture in some rock layers caused by an earthquake. Based on the evidence in the illustration, an earthquake occurred -

• Before layer W was deposited.

• Before layer X was deposited.

• After layer Y was deposited.

• After layer Z was deposited.

The illustration below shows rock layers from three different locations and fossils the rock layers contain. The fossils are all trilobites, ancient organisms that were different over time. Which conclusion can be drawn from the information in the illustration?

• The trilobite Cyclopygidae appeared most recently of those shown here.

• The trilobite Ceratopigidae appeared before all the others.

• The trilobite Remopleiridae is the oldest of all the trilobites.

• The trilobite Asaphidae appeared most recently of those shown here.
