Exploring Plate Tectonics: Causes of Plate Movements

What are the three main forces discussed that influence plate tectonics?

• Slab pull, ridge push, convection currents

• Convection currents, magnetic field, ridge push

• Magnetic field, slab pull, convection currents

• Ridge push, gravitational pull, magnetic field

What does the convection current in the Earth's mantle resemble?

• A static rock

• A boiling pot of water

• A spinning windmill

• A flowing river

According to Arthur Holmes, what happens to the mantle when it heats up?

• It contracts and sinks

• It expands and rises

• It remains static

• It breaks into pieces

What analogy is used to describe the movement of heat in the mantle due to convection currents?

• A staircase

• A slide

• A ladder

• A conveyor belt

What does the slab pull theory primarily depend on?

• The rotation of the Earth

• The gravitational pull on the subducting plate

• The magnetic field of the Earth

• The temperature of the ocean

How does slab pull affect the movement of tectonic plates?

• It does not affect plate movement

• It drags plates horizontally

• It pushes plates upwards

• It pulls plates downwards

How does the density of the slab influence its subduction speed according to slab pull theory?

• Lower density slabs subduct faster

• Density does not affect subduction speed

• Higher density slabs subduct faster

• Only temperature affects subduction speed

What role does the asthenosphere play in ridge push?

• It absorbs heat from the plates

• It heats the plates causing them to rise

• It provides a slippery surface for plates to slide

• It adds mass to the plates
