Explain how the process of erosion can lead to the formation of a canyon.

• Erosion deposits sediment in a flat area.

• Erosion wears away rock layers over time.

• Erosion causes volcanic eruptions.

• Erosion creates new rock layers.

Evaluate the impact of plate tectonics on the distribution of earthquakes around the world.

• Earthquakes are evenly distributed across the globe.

• Earthquakes are more common near plate boundaries.

• Earthquakes only occur in oceanic regions.

• Earthquakes are rare near plate boundaries.

• Mid-ocean ridge

• Volcanic island arc

• Fold mountain

Discuss how the Atlantic Ocean has changed over millions of years due to plate tectonics.

• It has remained the same size.

• It has expanded due to seafloor spreading.

• It has shrunk due to subduction.

• It has been replaced by a new ocean.
