Plate Tectonics Review

Front

What is the source of energy that drives Earth's plate tectonics, earthquakes, and volcanic eruptions?

Back

heat energy from Earth's internal layers

Front

Based on the information provided in the graphic, what can you conclude about the motion of the plates and how the land will be changed?

Back

The two tectonic plates are converging so that a mountain range forms on the continent.

Front

Why are volcanoes so common in mountain ranges such as the Andes?

Back

The Andes are in a region where a crustal plate is moving under another plate, which causes volcano formation.

Front

Which of these BEST describes the lithosphere?

Back

The lithosphere is made of rock that is cooler and easily changed.

Front

Fossils of the same plants and animals species have been found on continents separated by the Atlantic Ocean. What does this evidence support?

Back

The continents that are now separated by the Atlantic Ocean once formed a single landmass.

Front

Which type of plate boundaries should students study to understand seafloor spreading?

Back

an area where two crustal plates pull away from each other

Front

What type of heat transfer takes place in the mantle?

Back

convection

Front

Which phrase best describes the crust?

Back

The thin and solid outermost layer of Earth.

Front

What evidence supports that Earth has evolved over geologic time due to natural processes, based on Kannemeyeriid fossils found in Canada and Africa?

Back

Earth’s continents were once joined together

Front

Tectonic plates slide past each other at a transform boundary. Often, the plates get stuck and pressure builds up. Eventually, the plates snap free and release a large amount of energy as seismic waves. What event is being described here?

Back

an earthquake
