Tectonic Plates

Is there a pattern to the locations of earthquakes and volcanoes around the globe?

• No, earthquakes and volcanoes are random.

• Yes, earthquakes and volcanoes usually occur near the boundaries of tectonic plates.

• yes, earthquakes and volcanoes usually occur in the middle of tectonic plates.

• No, earthquakes and volcanoes usually occur under water.

the place where two different plates have contact.

• Pacific Plate

• Mountains

• Earthquakes

• Plate Boundaries

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
