One of the early principles of geology states that in undisturbed layers of rock, the oldest layers are found near the bottom, while the young layers are found near the top. Without this principle it would be much more difficult than it is now to —

• identify types of rocks

• track crustal movement patterns

• determine the relative ages of fossils found in rock layers

• predict upcoming earthquakes along existing fault lines

Which is the best evidence that continents that are now separated were once joined?

• A. Continents that were once joined now have similar climates.

• B. Identical plant and animal fossils are found on continents that are now separated.

• C. The cultures of the people on separated continents have similar languages.

• D. The migratory patterns of wildlife on separated continents are similar.

The modern model of the Plate Tectonic Theory suggests that the continents and the major tectonic plates drift slowly on —

• the ocean

• the Earth’s core

• the upper layer of the Earth’s mantle

• the atmosphere

How does the Ring of Fire help support the Theory of Plate Tectonics?

• It shows the magnetic striping and reversal at the mid oceanic ridge.

• It indicates similar fossils found on the islands in the Pacific Ocean.

• It indicates similar mountain ridges found in Japan and Australia.

• It reveals the seismic activity that occurs at plate boundaries.

In 1912, Alfred Wegener proposed the idea of continental drift, which states that the continents were once together in a giant supercontinent. Continents then broke apart and slowly moved away from each other. Alfred Wegener’s proposed theory was not widely accepted until much later. Which of the following is the most likely reason that the theory was not widely accepted?

• It looks like South America and Africa fit together like puzzle pieces.

• Fossils of similar land animals were found on both sides of the Atlantic Ocean.

• There was no explanation for the mechanism that could move the continents.

• Mountains made of similar rock types and ages were located on both sides of the Atlantic Ocean.

The figure below shows the rock layers in a hill. Which rock layer will have the oldest fossils?

• A 1

• B 2

• C 3

• D 4

Glaciers are giant mountains of ice that move very slowly when formed over land. They are so large that as they move, they scrape the surface of the land leaving deep marks and then deposit sediment picked up as the glacier scrapes the land moving further down their path. Strong evidence suggests that glacial scrapings and deposits existing in South America, Africa, India, and Australia were made by the same glacier at the same time. These continents are now separated by large bodies of water. This evidence helps to support the concept of -

• A sea floor spreading

• B glacial impact

• C global warming

• D continental drift
