• The lithosphere is the solid, outer part of Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
• 2 plates are called tectonic plates and plate boundaries
• Tectonic plates is massive slab of solid rock made up of Earth's lithosphere (crust and upper mantle). Also called lithospheric plate. (Kulay sa mga plates)
• Plate boundaries is edges that separate the tectonic plates with one another (line sa map)
• The 2 type of of lithosphere is Continental Lithosphere and Oceanic Lithosphere
• Continental relative age is older while Oceanic is younger
• Continental relative thickness is thicker than Oceanic, Oceanic is thin
• Continental relative desity is less dense while Oceanic is denser
• Continental type of rock is granite. Oceanic type of rock is basalt
• Primary plates are called Primary because the are larger than the secondary plates
• The earth has 7 primary plates
• Secondary plates have 8
• Primary:

  1. Pacific plate
  2. North American plate
  3. Eurasia plate
  4. African plate
  5. Antarctic plate
  6. Australian plate
  7. South American plate
• Secondary plates:

  1. Juan de fuca plate
  2. Nazca plate
  3. Cocos plate
  4. Caribbean plates
  5. Philliphine plate
  6. Arabian plate
  7. Indian plate
  8. Scotian plate
• Geologic events and features such as earthquakes, active volcanoes and major mountain ranges are distributed near or along plate boundaries.
