Plate Tectonics (AQA AS Geography): Exam Questions

A feature of the solid metal inner core associated with the Earth’s magnetic field.

Areas within the mantle where hotter, less-dense magma rises towards the surface.

Violent jets of molten lava from a vent or fissure during a volcanic eruption.

Zones where two tectonic plates slide past each other as one is subducted under the other.

A driving force of plate movement generated at mid-ocean ridges. Newly formed crust cools, becomes denser and so moves away from the centre of the ridge.

A driving force of plate movement generated at a subduction zone as an old, cold dense plate sinks into the mantle beneath.

Forces generated at conservative plate margins as one plate drags past another.

Warm convection currents within the mantle act like a conveyor belt, driving and carrying the plates of the lithosphere.

An archipelago formed of a series of volcanoes rising above sea level associated with an ocean trench and destructive plate margin.

An underwater mountain range associated with sea-floor spreading at a constructive plate boundary.

A linear lowland area between highlands formed as tectonic processes begin to pull tectonic plates apart.

Linear mountain ranges formed as two or more tectonic plates are pushed together often causing layers of sedimentary rocks to buckle and warp.
