Plate Tectonic Boundaries (A-Level)

Earthquakes and volcanoes are generally found...

• ...along plate tectonic boundaries.

• ...in the middle of plates.

• ...all over the world.

• ...in volcanic fracture zones.

What are convergent/ destructive boundaries?

• Where two plates pull apart.

• Where two plates come together.

• Where two plates slide side by side.

• Where two plates break.

What are divergent/ constructive boundaries?

• Where two plates pull apart.

• Where two plates come together.

• Where two plates slide side by side.

• Where two plates break.

What are transform/ conservative boundaries?

• Where two plates pull apart.

• Where two plates come together.

• Where two plates slide side by side.

• Where two plates break.

What is the lithosphere?

• The crust and the mantle.

• The mantle.

• The solid top section of the mantle and the crust.

• The crust.

What is the asthenosphere?

• The crust.

• The top section of the mantle (molten).

• The bottom of the crust and the mantle.

• The mantle.

What is the name of the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates?

• Subduction zone

• Tectonic zone

• Earthquake zone

• Continental zone

Which of these best describes a hot spot?

• A thermal plume rising from the mantle causing earthquakes.

• A weak spot in the plate, allowing magma to escape.

• A place in the plate where magma is closer to the surface.

• A thermal plume rising from the mantle creating volcanic island chains.

Collision plate boundaries can also be known as destructive plate boundaries. What makes them different to a 'normal' destructive boundary?

• Continental plate meets continental plate.

• There is no subduction.

• All of the answers are valid.

• There is no magma activity.

Which sequence correctly describes a destructive plate boundary.

• Continental crust moves towards continental, one continental plate is subducted, volcanoes occur.

• Oceanic crust moves towards continental, oceanic is subducted, volcanoes and earthquakes occur.

• Oceanic crust moves towards continental, continental is subducted, volcanoes and earthquakes occur.

• Oceanic crust moves towards continental, oceanic is subducted, only earthquakes occur.
