IS Plate Tectonics Shortened Review

What do you notice about the lines of earthquakes and volcanoes and where they seem to occur on Earth’s surface? There is more than one correct answer.

• Earthquakes and volcanoes are found in similar patterns around the globe.
• Volcanoes are found in more locations/places than earthquakes.
• Earthquakes and volcanoes are found in opposite patterns around the globe.
• Earthquakes are found in more locations/places than volcanoes.

Define convergent plate boundary.

• Two pieces of the surface are moving away from each other
• Two pieces of the surface are coming towards each other
• Two pieces of the surface are moving parallel to one another
• One piece of the surface moves North and another moves South

Define divergent plate boundary.

• Two pieces of the surface are moving away from each other
• Two pieces of the surface are coming towards each other
• Two pieces of the surface are moving parallel to one another
• One piece of the surface moves North and another moves South

Define transform plate boundary.

• Two pieces of the surface are moving away from each other
• Two pieces of the surface are coming towards each other
• Two pieces of the surface are moving parallel to one another
• One piece of the surface moves North and another moves South

Which of the following statements best describes how the plates on the surface of Earth move?

• Plates stay where they are and do not move.
• Plates move sometimes and do not move other times.
• Plates are moving slowly, and their direction is affected by nearby plates.
• Plates moved in the distant past, but they do not move today.

• D

Four regions (A through D) are marked on the figure. Which regions show one plate moving away from another plate?

On what type of boundary are ridges (mid-ocean ridge) formed?

• transform
• divergent
• convergent

What causes deep ocean trenches to form?

• Trenches are formed at a convergent plate boundary; the oceanic crust is going beneath the continental crust

• Trenches are formed at a convergent boundary where two pieces of oceanic crust meet.

• Trenches are formed at a divergent boundary where two pieces of crust are pulling apart and a trench is formed from the separation of the crust.

• Trenches are formed at a transform boundary when the friction builds up until a trench is created to release the stored energy
