Climate factors & definition

  1. 1. Climate LessonWhat factors contribute to aregion’s climate?www.makemegenius.comFree Science Videos for
  2. 2. www.makemegenius.comFree Science Videosfor KidsFor FreeScience Videosfor Kidswww.makemegenius.comFree Science Videos for Kids
  3. 3. Weather vs. Climate?• Weather: Atmospheric conditions(temperature, rainfall, etc…) at a specificpoint in time• Climate: Atmospheric conditions(temperature, rainfall, etc…) of a regionover a long period of timewww.makemegenius.comFree Science Videos for
  4. 4. Factors affecting Climate• Zones of Latitude• Wind Currents• Ocean Currents• El-Nino• Global Warmingwww.makemegenius.comFree Science Videos for
  5. 5. Zones of LatitudeA region’s latitude (distance from the equator)can impact its climate.PolarPolarTemperateTropical TropicalTemperatewww.makemegenius.comFree Science Videos forKids
  6. 6. Zones of Latitude• Tropical Zones: Warm weather yearround. Area between the Tropic of Cancer (23 ½ º N) and theTropic of Capricorn (23 ½ º S).• Temperate Zones: Warm summersand cold winters (four seasons). Areasbetween Tropic of Cancer (23 ½ º N) and Arctic Circle (66 ½ º N)and Tropic of Capricorn (23 ½ º S) and the Antarctic Circle (66 ½ ºS).• Polar Zones: Cold year round. Areasnorth of the Arctic Circle and south of the Antarctic Circle.www.makemegenius.comFree Science Videos for
  7. 7. Wind Currents• Wind currents help distribute the sun’s heat from onepart of the world to another.• Warmer air has lower pressure than cooler air. Thecooler air rushes into the low pressure areas causingwind.• Warm air currents make areas warmer than normal.Cold air currents make areas cooler than normalHigh Pressure AirLow Pressure AirWind blows from areas of HighPressure to Low Pressurewww.makemegenius.comFree Science Videos for
  8. 8. Ocean Currents• Ocean current move in large circular systems• Ocean currents affect temperature and precipitation ofan area.• Warm ocean currents make surrounding areas warmerand rainy.• Cool ocean currents make surrounding areas cooler anddrierWarm OceanCurrentCool OceanCurrentCooler andDrierWarmerand Rainywww.makemegenius.comFree Science Videos for
  9. 9. El Niño• The natural warming of waters off the westcoast of South America about every 2 – 7years due to a reversal of wind direction.• El Nino causes floods and mudslides inthe Americas.• El Nino causes droughts in Australia andAsia.www.makemegenius.comFree Science Videos for
  10. 10. Global Warming• Global Warming is the build up of carbon dioxide(greenhouse gases) in the atmosphere trapping heat andcausing increase temperature and shifting weatherpatterns.• Global Warming is being caused by both the humanrelease of greenhouse gases from the burning of fossilfuels (oil, coal) and a natural warming cycle the Earth isgoing through• As the global temperature begins to rise many changeswill occur to climates around the world• Check the global warming video onwww.makemegenius.com?www.makemegenius.comFree Science Videos for
