This document provides an overview of key concepts about plate tectonics and geological hazards. It outlines topics like the composition of the Earth's layers, how plate tectonics drives motions at different plate boundary types, and how this relates to the formation of earthquakes, volcanoes, and landforms. The document also discusses measuring and responding to hazards, highlighting both short and long-term strategies to plan for volcanic eruptions and quakes.

1. Restless Earth
What I should know…
o What oceanic and continental tectonic plate are and how and why are they
different
o The different layers of the Earth’s interior and how they differ
o Why the asthenosphere is an important part of the mantle
o How convection in the mantle drives plate tectonic motion
o That there are different types of plate margins
o How new oceanic crust is subducted at destructive plate margins
o How earthquakes and volcanoes form at destructive plate margins
o Why earthquakes occur along conservative plate margins
o Why fold mountains form in collision zones
o How destructive collision zone earthquakes can be
o How to explain the global pattern of earthquakes and volcanoes
o How shield volcanoes and composite volcanoes form from different types of
magma
o How hazards are measured using VEI, Richter and Mercalli scales
o The difference between primary and secondary impacts
o Detailed causes and impacts for two named volcanoes
o Detailed causes and impacts for two named earthquakes
o How earthquakes and volcanoes can be planned for and even predicted
o The different types of hazard response, both short and long term
