Transcript of Climate good one

  • 1.Climate

2.

  • A climate is the pattern of weather that occurs in an area over many years.

3. 1.Determines the types of plants or animals that can survive and influences how people live. 4. 2.Elements that are averaged to determine climate: temperature, precipitation, air pressure, humidity, and days of sunshine. 5. Factors that affect climate

  • 1.Latitude distance north or south of the equator.

6. Tropics

  • Regions between latitudes 23 N and 23 S
  • Sun shines almost directly overhead, keeping temperatures high

7. Polar Zones

  • extend from 66 N and 66 S to the poles sun shines at a low angle, keeping temperatures low

8. Temperate Zones

  • between the tropics and the polar zones moderate temperatures

9. Why are isotherms not parallel with latitude? 10. Large bodies of water affect the climate of coastal areas by absorbing or giving off heat 11. Ocean currents can bring cool or warm temperatures and moisture to coastal areas 12. Mountains affect their own climate as well as the climates of nearby areas 13. At the same latitude, the climate of on a mountain is colder than the climate at sea level 14.

  • Mountains cause air to rise, cool, and condense, creating a wetter climate on the windward side of the mountain and a much drier climate on the leeward side.

15. 16.

  • Because of their large areas of solar radiation absorbing asphalt and concrete, cities frequently have higher temperatures than surrounding areas.

17. Section II Climate Types 18. Adaptation

  • any structure or behavior that helps an organism survive in its environment

19. Structural adaptations are body structures that help organisms survive in certain climates.

  • a the fur of mammals insulates them from cold temperatures
  • b a cactuss thick, fleshy stem helps it hold water

20. Behavioral adaptations

  • a hibernation a period of greatly reduced activity during cold months
  • b estivation similar to hibernation, an inactive state that occurs during periods of intense heat

21. Section III - Climate Changes 22. Seasons

  • short periods of climatic change caused by changes in the amount of solar radiation an area receives

23.

  • 1.As Earth revolves around the Sun, different areas of Earth are tilted toward the sun.

24. 25.

  • 2.The tropics do not experience much seasonal temperature change.

26.

  • 3.High latitudes near the poles experience great seasonal temperature change.

27. El Nino an occasional climatic event in which strong Pacific winds weaken and sometimes reverse. 28. Effects of El Nino

  • a Ocean temperatures near Peru heat up

29.

  • b The position and strength of one of the jet streams may be altered, changing wind and precipitation patterns around the world.

30.

  • c - Africa and Australia may experience drought.

31. La Nina The winds blowing across the pacific are stronger than normal 32. At times in the past, Earths climate was much warmer or colder than now. 33. Causes of climatic change can operate over short or very long periods of time 34.

  • 1.Solar radiation is blocked by larger numbers of solid and liquid particles entering the atmosphere

35. a.Catastrophic events such as volcanic eruptions and meteorite collisions can cause climatic change 36. 37.

  • Pollution can also cause climatic change

38.

  • 4.The movement of Earths crustal plates affects the transfer of heat on Earth.

39. Climatic Changes Today

  • Greenhouse Effect a natural heating process that occurs when certain gasses such as carbon dioxide, methane, and water vapor in earths atmosphere trap heat.

40.

  • Global Warming Earths average global surface temperature is rising, possibly due to the increase in greenhouse gasses in our atmosphere.

41. Human activities affect the air on Earths surface

  • a.burning fossil fuels increases the amount of carbon dioxide in the atmosphere.

42.

  • Deforestation results in fewer trees to absorb carbon dioxide from the atmosphere.

43. Individuals CAN help reduce the amount of carbon dioxide in the atmosphere. 44.
