• Plate Tectonics


  Lesson 1
• Present -Past
• Epicenter


  The part of the earth's surface directly above the focus of an
• Mountain


  • A landmass that projects above its scrroundings and its higher than a hill
• Siesmograph


  Record vibrations within the earth and of the ground
• Earth quake


  Shaking or trombling of the earthy
• Volcano


  • A vent or fissure in the planet's crust through which lowa, ash rock and glasses eruppt
• Earth Quake under the sea


  Can cause tsunami
• Ring of Fire


  Also called circum pacific belt
• focus


  凶。
• Sit properly


  Back should be touching the chair back rest
• Change position regularly


  Sit on couch, chair, or floor
• Dim lighting


  Rather than strong or no lighting to avoid eye damage
• Stretch


  Use commercial breaks to change positions, get up, walk around, and do gentle stretches
• Don't watch TV in bed

  Often leads to neck and back ache
• Plate tectonics explains the features and movement of the earth's surface in the present and the past
• What's the mystery word challenge

  1. Level 1: Location above the focus earthquake

  2. Level 2: Landform with steep slopes larger than hills

  3. Level 3: Instrument to detect and measure earthquake intensity

  4. Level 4: Violence, shaking, destruction, movement within the earth's crust

  5. Level 5: Opening in earth's crust, molten rock
• Lithosphere


  • 100 kilometer thick layer of solid rock including the crust
• Asthenosphere


  • Upper mantle beneath the lithosphere, solid but softer due to high pressure and temperature, allows convection
• The earth's lithosphere is broken into numerous segments called plates
• Seven large plates


  • African
  • Antarctic
  • Eurasian
  • North American
  • South American
  • Indian
  • Australian
  • Pacific
• Earthquakes, volcanoes, and mountain ranges are concentrated in narrow zones, particularly along plate boundaries
• The Philippines is situated in the Pacific Ring of Fire, a geologically active area with frequent earthquakes and volcanic eruptions
• About 90% of the world's earthquakes occur in the Pacific Ring of Fire
