• The Philippine plate is surrounded by 2 major plates which is the Eurasian and Australian plate
• 7 Major plates

  • North American
  • South American

  • African
  • Pacific
  • Eurasian
• 8 Minor plates

  • Philippine
  • Juan de Fuca

  • Arabian
  • Indian
• There are 2 major plates that are oceanic, they are the Pacific and Antarctic plates
• The 2 minor continental plates are the Arabian and Indian plates
• 7 major plates: North American, South American, Australian, Antarctic, African, Pacific, Eurasian
• Asthenosphere is at the upper mantle. From the Greek word "asthenes" meaning "weak"
• Lithosphere is the rigid outer part of the Earth. Located at the upper mantle and the whole crust. From the Greek word "lithos" meaning "hard"
• Continental crust is where most continents lies. It is thicker but less dense and is composed of Granite.
• Oceanic crust is found under the the oceans. It is thinner but more dense and is composed of Basalt.
• Plate Tectonic Theory

  Earth's crust is broken into segments called plates that interacts in various ways, thus producing earthquakes, volcanoes, mountains, and other geological structure. Each plate is slowly but continuously moving
• Mantle is thick and hot, made out of rocks and generally the largest layer of the Earth.
• Crust is the outermost layer, it is thin ang brittle.
• Outer core - liquid metal, fiery sphere, hot and dense.
• Inner core - inner most geological layer.
• The core is composed of Iron and Nickel
• Mantle is primarily composed of 4 elements: Iron, Magnesium, Silicon, and Oxygen
• Countries from Europe that is unlikely to experience earthquake

  • Poland
  • Belarus
  • Ukraine
• Countries from South America that is unlikely to experience earthquake

  • Uruguay
  • Paraguay
• Countries from the Middle East that is unlikely to experience earthquake

  • Qatar
  • Saudi Arabia
