Flashcard- Plate Tectonics

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

What type of boundary is shown here, and what land formations will it create?

Back

Convergent Boundary, Subduction Zone, Creates Volcanoes

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

Divergent Boundary

Front

What type of heat transfer takes place in the mantle?

Back

convection

Front

The three compositional layers of Earth are the core, the mantle, and the crust. Which phrase best describes the crust?

Back

The thin and solid outermost layer of Earth.

Front

Scientists found fossils of Kannemeyeriid in Canada and Africa. What does this suggest about Earth's geologic history?

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
