Pangea is:

• a time when all the continents were moving away from one another

• a time when all the continents were connected making one supercontinent

• a time when all the continents were grouped into two medium sized continents

Continental drift is:

• Wegener's theory that the continents were once apart and then drifted back together.

• Wegener's theory that all fossils must have lived on continent and then they moved away from each other.

• Wegener's theory that the continents were once connected and then drifted apart from each other.

Plate Tectonic is:

• The theory that the Earth's plates are constantly moving.

• The theory that the Earth's plates are only moving in one direction.

Which of the following provides evidence for past tectonic plate motions?

• Matching rock type and rock formations can show the way the continents were once attached.

• Glacial evidence has been found in areas where glaciers could not exist if the continents were in their current location.

• Ancient life forms preserved as fossils can tell us what organisms existed and where they were. Matching the fossils can show that land masses were once connected.

• All of the above.

• Cynognathus, Glossopteris, and Lystrosaurus

• Glossopteris, Cynognathus, and Mesosaurus

By studying the distribution of different types of fossils, geologists have determined that some plates have traveled great distances. Evidence to support this comes from the fact that –

• some fossilized organisms have only been found on one continent.

• fossils of organisms that lived in warm climates have been found in arctic environments.

• species of organisms in the fossil record have changed over geologic time.

Fossil

• Physical evidence of a plant or animal that lived long ago

• Theoretical evidence of a plant or animal that lived long ago

• Only physical evidence of an animal that lived long ago

Tectonic Plates are:

• Huge pieces of the top layer of the Earth that are in constant motion, made up of the crust and top layer of the mantle.

• Huge pieces of the middle layer of the Earth that scientists theorize are not in motion

• Huge pieces of the top and middle layer of the Earth that are in constant motion

Continental Crust

• The solid rock layer that makes up the top layer of land that we live on

• The solid rock layer that makes up the top layer of land that we find in the ocean
