Patterns in the Locations of Volcanoes and Earthquakes Related to Tectonic Plate Boundaries

Describe the most likely relationship between these mountains and nearby tectonic plates.

• The mountains are probably formed by earthquakes

• The mountains are probably formed by the movement of glaciers

• The mountains are probably located near the edge of 2 tectonic plates.

• The mountains are probably formed by running water.

Peru and Chile are part of South America, which sits on the South American tectonic plate. The Nazca plate is moving toward the South American plate. It is pushed downward, which causes it to slide under the South American plate. Based on this information, what feature could we expect to see off the coast of Peru and Chile?

• new Continent formation

• Poor fishing conditions

• Deep ocean trench

• Severe tropical storms

• Oceana

• Pangea

• North America
