Understanding Plate Boundaries and Their Hazards

What are plate boundaries also known as?

• Plate junctions

• Plate crossings

• Plate margins

• Plate centers

Where do constructive (divergent) plate boundaries mostly appear?

• In the mountains

• At the bottom of the sea

• Near river deltas

• On continents

What natural hazard is commonly found at constructive plate boundaries?

• Volcanoes

• Tsunamis

• Landslides

• Tornadoes

What happens at a convergent (destructive) boundary when an oceanic plate meets a continental plate?

• Both plates float into the atmosphere

• Both plates dissolve

• The oceanic plate is forced underneath

• The continental plate is forced underneath

What causes powerful earthquakes at destructive boundaries?

• Volcanic eruptions

• Plates sliding gently past each other

• Plates grinding against and getting stuck on each other

• Sudden temperature changes

What is created when two continental plates collide at a collision boundary?

• Large lakes

• Deep sea trenches

• Mountain ranges

• New oceans

Why don't volcanic eruptions occur at collision boundaries?

• Because of the lack of magma rising up

• Due to the cold temperature

• Because of the high altitude

• Due to the presence of water

What happens at conservative (transform) boundaries?

• Plates disappear

• Plates slide past each other

• Plates are created

• Plates merge together

Why do earthquakes occur at conservative boundaries?

• Because of volcanic activity

• Because of sudden plate creation

• Due to plates melting

• Due to plates getting stuck as they slide past each other

Which of the following is not a type of plate boundary discussed?

• Reconstructive

• Conservative

• Destructive

• Constructive
