• Lithosphere


  Composed of the crust and the upper mantle
• The lithosphere is in constant but very slow motion
• Plate Tectonics Theory


  The entire lithosphere of the Earth is broken into numerous segments called plates
• Plates


  • Seven relatively large plates and several smaller ones, including the Philippine plate
• As plates interact along their margins, important geologic processes take place, such as the formation of major mountain ranges, active volcanoes, and earthquake epicenters
• Where there are earthquakes

  Crusts can either meet or move apart and form mountains and volcanoes
• What is the lithosphere composed of?

  Crust and upper mantel
