Unformatted text preview: 1. Draw and label each of the plate boundaries. (notebook) 2. Explain where earthquakes and volcanoes occur and why they occur there. Earthquakes : a) divergent boundaries the spreading and cracking of plates makes shallow earthquake b) convergent boundaries the collision of the plates causes vibration (deep and strong) c) Transform boundaries- rubbing together of plates in opposite direction causes strong vibrations Volcanoes: a) divergent boundaries- magma flows through ocean ridge and cools at sea floor. Cooled magma though lithosphere can build up and create island arcs which are often active volcanoes b) Convergent boundaries sinking ocean lithosphere under the continental crust brings material that is melted and formed into magma, the is pushed up because it is less dense and it cools as it rises however if hot enough will make it to the service and erupt 3. Explain some of the differences between plate boundaries. For example, why are there deep earthquakes at convergent boundaries and shallow earthquakes at divergent...
