Tectonic Plates & Boundaries

What causes the motion of the plates?

• Convection in the outer core

• Magnetic reversals

• Energy from the Sun

• Convection in the mantle

Which of the following best describes the relationship between volcanoes, large earthquakes, and tectonic plates?

• Earthquakes anywhere; volcanoes on the edges of plates

• Volcanoes and earthquakes anywhere, but mostly at boundaries

• Volcanoes anywhere; earthquakes on the edges of plates

• Volcanoes and earthquakes are distributed equally on the map

What geologic feature should be found at a divergent boundary?

• A flat plain

• A dome

• A ridge

• A subduction zone

Where can you find divergent boundaries?

• On land only

• In the ocean only

• Both land and ocean

• None of the above

Where are most divergent boundaries found?

• The ocean floor

• The edge of a continent

• In the middle of a continent

• They are equally distributed around the world

Why did the continental plate get volcanoes?

• It gets stuck and folds
• It has a subducted plate under it that melts
• It is more dense

Why is there a trench in the water?

• Because of the basalt 
• Because of the melting oceanic crust
• Because the oceanic plate is subducting making a low spot
• Because the oceanic plate is stuck and folds downward
