Grade 10 Science Quiz: Plate Movement

What is the primary source of heat that drives mantle convection?

• Crust

• Outer core

• Mantle

• Lithosphere

Which of the following best describes mantle convection?

• Pulling force caused by subducting slabs

• Pushing of crust from ridges toward trenches

• Movement of heat rising from the core to the mantle

• Friction between plates at transform faults

The process where new crust forms at mid-ocean ridges and pushes older crust away is called:

• Slab pull

• Slab suction

• Ridge push

• Subduction

Which driving force involves the sinking of a cold, dense oceanic plate into the mantle?

• Ridge push

• Slab pull

• Mantle convection

• Collisional resistance

Slab suction occurs when:

• A plate moves past another at a transform fault

• One plate resists subduction due to its density

• Friction pulls both plates downward into a trench

• Heat pushes plates upward

What is the role of drag force in plate tectonics?

• It pushes plates toward each other

• It creates new crust at mid-ocean ridges

• It resists the movement of lithospheric plates

• It increases the convection current speed

Which resisting force occurs due to friction between two colliding plates?

• Drag force

• Ridge push

• Slab pull

• Slab suction

What happens in slab resistance?

• It helps in forming mid-ocean ridges

• It opposes forces in subduction zones

• It causes plates to move faster

• It supports transform boundaries

Transform fault resistance is due to:

• Pressure from magma beneath the crust

• Friction between plates sliding past each other

• The pull of the subducting plate

• Convection currents moving upward

The friction opposing slab pull in a subduction zone is called:

• Ridge push

• Drag force

• Collisional resistance

• Mantle convection
