  • geology is the study of the earth
  • atmosphere is the gas envelope
  • atmosphere is composed of 78% nitrogen, 21% oxygen, and 1% other gases
  • LAYERS OF ATMOSPHERE (bottom to top)
    1. troposphere
    2. stratosphere
    3. mesosphere
    4. thermosphere
  • hydrology is the study of water on and within earth
  • dew point is the temperature at which condensation of water occurs
  • precipitation is the water released to the surface of the earth
  • hydrosphere is the liquid part of earth's surface
  • earth's surface is covered with 75% water
  • el nino is the appearance of unusually warm air water in the pacific ocean
  • la nina is the unusual cold temperatures in the ocean waters of equatorial pacific
  • Plate tectonic theory states that the lithosphere is divided into 6 major plates that are constantly moving
  • plate tectonic theory is the foundation of continental drift theory
  • extinct is a type of volcano that has shown inactivity for a long period of time
  • pacific ring of fire is the narrow chain of volcanoes at the boundaries of the pacific ocean
  • lava is a magma that reaches the earth
  • seismology is the study of earthquake
  • focus is the place where earthquakes begin
  • epicenter is the point on the earth's surface directly above the focus
  • CAUSES OF EARTHQUAKE:
    Tectonic is movement of tectonic plates
    Volcanic is movement of molten magma within the earth
  • tidal wave is a large mass of water displaced by earthquakes
  • seismograph is used to detect and record earthquakes
  • magnitude is a scaled measure of the energy released by earthquakes
  • richter magnitude scale is used to measure magnitude
