Formation of Mountains Plate Tectonics LI: We are learning about the role that tectonic activity plays in creating landforms  Plate Tectonics Video- Plate tectonics https://www.youtube.com/watch?v=_ Ugwf6IaE_k As you watch the video, make notes on the key information. Be ready to share your notes. What is the theory of Plate Tectonics? The Earth's Crust consists of seven major tectonic plates (there are several smaller ones) These tectonic plates float on the semi-molten mantle in a pattern resembling a jigsaw puzzle The plates move slowly – typically a few centimeters a year Tectonic Plates Plate Tectonic Jigsaw Complete the plate tectonic jigsaw Glue this into your workbooks Tectonic Plates: Creating Landforms As the plates move they create landforms Diverging margins – when the plates move apart. This causes the formation of ocean trenches and rift valleys Converging Margins – the collision of the plates, leading to the formation of mountains and volcanos Tectonic Plates: Volcanoes Volcanoes: Predominantly found along converging margins or subduction zones Subduction: Occurs when a heavier oceanic plate converges with a continental plate, leading to the formation of magma that fuels volcanoes (e.g., Mount Pinatubo in the Philippines). Tectonic Plates: Earthquakes Earthquakes: Mostly occur near converging plates or along transform margins. Transform Margins: Plates slide past each other, potentially becoming stuck and releasing energy as earthquakes (e.g., San Andreas Fault in California).  ACTIVITY: Match the key word with the correct definition  Geo Skills: PQE Geo Skills: PQE exemplar..  PQE -Plate Tectonics Open the website https://www.geolsoc.org.uk/ Plate-Tectonics (Link in on the class page) Try turning each layer on, what do you notice from looking at each layer? Q- Describe the distribution of volcanoes as shown on your map. What does this distribution have in common with the plate boundaries?  How was Hawaii formed? How was Hawaii formed? Watch the video carefully! Your task is to write a summary to explain how the Hawaiian Islands were formed. You should have approximately 10 key points.  Plenary- Media analysis Read the following article: https://theconversation.com/melbourne-earthquake-2023-are-they-becoming-mo re-common-a-seismology-expert-explains-206589 1. What was the magnitude of the earthquake that struck the greater Melbourne region last night, and where was its epicenter located? 2. How many reports of people feeling the earthquake have been received by Geoscience Australia, and how far away from the epicenter was the farthest reported location? 3. Are earthquakes becoming more common in Melbourne, and what is the average frequency of felt earthquakes in the greater Melbourne region each year? 4. What factors determine whether a person will feel an earthquake, and why do shallow earthquakes tend to produce stronger ground-shaking?
