Earthquakes o Occur where rocks being stressed suddenly break along a new or pre-existing fault o CQ: Which types of faults are found at divergent boundaries? NORMAL Earthquakes and Plate Tectonics o CQ: Where do we find the majority of deep earthquakes? Subduction Zones o CQ: What type of faults do you expect in Iceland where the Mid-Atlantic Ridge is exposed on land? NORMAL Elastic Rebound Theory o Earthquakes are result of stress built up over time o Stress gradually builds as tectonic forces deform rocks on either side of a locked fault side of a locked fault o When the stress exceeds the strength of rocks along the faults the faults then slips releasing the stress suddenly and causing an earthquake o Process repeats again and again o Earthquakes occur when stress from tectonic forces builds up on a locked fault over time, eventually exceeding the rock strength and causing fault to slip o Rocks that are deformed as stress builds up along a fault rebound elastically,
