• Destructive

• Conservative

• Convergent

What is the correct order from inside to out?

• Crust, lava, inner core, outer core

• Inner core, outer core, mantle, crust

• Crust, mantle, outer core, inner core

• Mantle, crust, inner core, outer core

Whilst still debated amongst scientists, which of the following are thought to be the processes responsible for tectonic plate movement?

• Ridge push

• Slab pull

• Convection currents

• Subduction

What is being described: "relatively thin (10km) and young (50 million years), dense, made of basalt

• Oceanic crust

• Continental crust

Earthquakes occur on ALL plate margin types but which TWO plate margin types have the more powerful, destructive earthquakes?

• Destructive margins

• Constructive margins

• Conservative margins

Earth's core is radioactive. How hot do scientists believe it could be?

• 1 million degrees celsius

• 5,500 degrees celsius

• 650,000 degrees celsius

• 550 degrees celsius

"The process by which one tectonic plate is forced down beneath another less dense plate into the mantle where it melts and is destroyed" is the definition of which key term?

• Convection

• Subduction

• Friction

• Slab pull

Iceland was formed on a constructive plate margin. Which two tectonic plates created the margin?

• North American and Eurasian

• Pacific and Eurasian

• South American and African

• Arctic and North American

Lava at destructive plate margins is viscous and sticky. Which type of volcano does this create?

• Composite cone

• Shield

• Supervolcano

• Fissure
