WA1 Revision

How many types of divergent plate boundaries are there?

• 1

• 2

• 3

• 4

What tectonic landform is this?

• Volcanic Island

• Mid-Oceanic Ridge

• Fold Mountains

• Rift Valley

Which of the following is NOT responsible for tectonic plate movement?

• Convection Currents

• Sea-Floor Spreading

• Slab-Pull Force

• Subduction

What is the state of the outer core?

• Solid

• Liquid

• Gas

• Plastic-Like

Which of the following statement about the continental crust is FALSE?

• Composed mainly of basalt

• It is around 35 to 70km thick

• It is lighter and less dense than oceanic crust

• It is brittle (i.e. susceptible to fracturing)

Where can the youngest rocks on Earth be found?

• At the Himalayas

• Along the Mid-Atlantic Ridge

• Adjacent to Continental Plates

• Near Rift Valleys

Which of the following combination of plate(s) is a divergent plate boundary?

• Arctic-North American Plate

• North American-Pacific Plate

• North American-Eurasian Plate

• Indian-Eurasian Plate

On average, what is the speed of movement of tectonic plates in one year?

• 2mm

• 2cm

• 2m

• 2km

Which of the following landforms/features CANNOT be found at a continental-continental divergent plate boundary?

• Fold Mountains

• Rift Valley

• Block Mountains

• Fractures

Which of the following statements best describe slab-pull force?

• Slab-pull force is driven by sea-floor spreading at the mid-oceanic ridges

• The gravitational forces help to pull the oceanic plate downwards

• As the oceanic plate subducts and sinks, it pulls the rest of the plate behind it

• The downward portion of the convection current pulls plate downwards into Earth's core
