• 5 factors affecting climate

  • Latitude
  • Altitude
  • Topography
  • Bodies of water
  • Ocean current
• three major climate zone

  • Tropical zone
  • Temperate zone
  • Polar zone
• As the latitude increases, temperature decreases
• Latitude

  It is an imaginary line that is parallel to the equator.
• Leeward side

  The air move down to the opposite region
• Snowy day is a weather of the day when lots of snow has fallen
• Arid - is a dry climate sub-type in which there is a severe excess of evaporation over precipitation
• Affects of weather

  • temperature
  • wind
  • air pressure
  • humidity
  • precipitation
• Thermometer is used to measure the temperature
• wind

  it is the movement of the air in the atmosphere
• Wind vane

  tells the direction of the wind
• Anemometer

  measure the wind speed
• Barometer

  instrument used to measure atmospheric pressure
• Humidity

  it is the amount of the water vapor in the air
• altitude increases, temperature decreases
• Direct rays

  area receive from the sun experience WARM CLIMATE
• Oblique ray

  those area that receives from the sun will experience COLD CLIMATE
• tropical region

  • experience 2 kinds of weather: sunny and rainy
  • Located in 0 to 23.5 degree from the equator
• Temperate region

  located between the subtropical and the polar region
