Faults: breaks in the Earth’s crust Faul t Plate Plate Spreading Boundaries • two plates moves apart • in water: sea floor spreading • on land: rift forms (deep trench) Colliding Boundaries • two plates come together Sliding Boundaries • two plates moves past each other • Subduction: one plate is pushed under the other • Causes earthquakes • Both plates can push each other up and make a mountain Yearly Average Temperature Sea Floor Spreading https://www.youtube.com/watch?v=pHWceRySDb8 https://www.youtube.com/watch?v=k-_Z6p5cjKg https://earth.google.com/web/@-25.62785005,107.58190958,4192.58462055a,18004320.6863451d,35y,0h,0t,0r/data=Ci4SLBIgOTJmOT k0NTc0Y2FhMTFlODkzNDI3MTM3ODRlMDYzMjMiCGxheWVyc18w Trenches https://www.youtube.com/watch?v= X13ntFfwXqY Subduction https://www.youtube.com/watch?v= CcRerU_8wpI Mountain Forming https://www.youtube.com/watch?v=Fd_XqYE2 BWY Sliding Boundaries https://www.youtube.com/watch?v=e7ho6z32yyo https://youtu.be/LdlEufZop-Y Hawaii *Hawaii was formed by a hot spot in the mantle that pushed through to the top- volcano. As the plate moved, the hotspot moved- forming different islands. https://www.youtube.com/watch?v=T1cES1Ekto
