Total questions: 10
Worksheet time: 5mins
What are the mechanisms that drive tectonic plate movement?
Oceanic Ridge, Convection Current, Trench suction
Continents move apart, Continents move together, Mantle Core
Magma rises, Plate pushed, Plate pulled
Mantle convection, Ridge push, Slab pull
What is mantle convection?
Semi-molten rock cooling and sinking
Convection currents in the semi-molten mantle
Heat generated by radioactive decay in the core
Semi-molten rock becoming less dense and rising
How do convection currents cause plate movements?
Semi-molten rock spreads out carrying the plates
Semi-molten rock cools and becomes more dense
Semi-molten rock becomes less dense and rises
All of the above
What is ridge push?
Plate pushed by the weight of a mid-ocean ridge
Magma rising and cooling to form new plate material
Plate pulled by the weight of its cold, dense subducting section
Plate sinking back into the mantle under gravity
What is slab pull?
Plate pulled by the weight of its cold, dense subducting section
Plate pushed by the weight of a mid-ocean ridge
Plate sinking back into the mantle under gravity
Magma rising and cooling to form new plate material
What causes continents to move apart?
Mantle convection
Slab pull
Ridge push
Oceanic Trench
What causes continents to move together?
Oceanic Trench
Slab pull
Ridge push
Mantle convection
What is the process of mantle convection?
