Mantle - Answer A layer of rock that due to high temperatures is deformable (plastic) and flows very slowly Mantle Plumes - Answer Concentrated areas of heat convection. At plate boundaries they are sheet like, whereas at hotspots they are columns Subduction - Answer Process of one plate sinking beneath another at a convergent (destructive) plate boundary Focus - Answer Exact point where an earthquake origionates Epicentre - Answer Point on the earth's surface di...

A-Level Geography – Tectonics Exam Review 2023 (EQ1) What is the global distribution of earthquakes? - Answer-Most earthquakes = near tectonic plate boundaries - clusters of foreshocks, main quakes + aftershocks. ~70% earthquakes = 'Ring of Fire', Pacific Ocean. Most earthquakes --> destructive + conservative plates. (EQ1) What is the global distribution of volcanoes? - Answer-Most volcanoes = near a tectonic plate boundary. North + South America --> active volcano zones. So...

One process that occurs only at convergent plate boundaries - Answer- Subduction -Volcanic eruptions produce a number of different hazards, including lava flows, pyroclastic flows and gas eruptions as well as secondary hazards such as lahars and jokulhaups. The main reason volcanic eruptions vary in magnitude is as a result of the type of volcano that is erupting which will produce various hazards to differing degrees. Magnitude is mainly measured by the VEI that measures things such as the v...
