This document contains detailed notes on Plates and Basins from Chapter 7: Plate Tectonics of the A Level Geology course. It includes all the information required to secure a top grade in this part of the course. These notes took me many hours to complete and are how I revised for my exams.
, Why is there Magma at the MOR?
• The two plates are moving away from each other, so the pressure on
the mantle decreases, which causes partial melting.
• This low density melt and hot mantle holds the ridge up and keeps it
buoyant.
, Earthquakes as Evidence
• Shallow focus earthquakes are caused by:
Normal faults
Transform faults
Harmonic tremors
