1. Weather & Climate

3. Weather is the day to day changes in the atmosphere. temperature precipitation wind speed wind direction cloud cover humidity air pressuresunshine What is the difference between weather and climate?

4. Climate is the overall pattern of weather, usually based on an average over 30 years. Click on the buttons to find out about these types of climate. What is the difference between weather and climate?

5. The water cycle

6. The water cycle in more detail

7. Precipitation is water from the atmosphere. It can be in solid or liquid form. Name as many different types of precipitation as you can! What is precipitation?

8. High Pressure Higher pressure than what is normal for that altitude. Brings clear skies and fair weather. Picture taken from: http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/high_pressure.html

9. Low Pressure A low pressure region is associated with rising air. Clouds, rain, and very strong winds occur. Picture taken from: http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/low_pressure.html

11. Frontal rain

12. Convectional rain

13. Relief rain

14. Wind Caused by the earth’s surface being heated unevenly by the sun. Why would the earth’s surface heat unevenly? Weather animation

15. Temperature Temperature - Air higher in pressure is usually cooler air and air lower in pressure is usually warmer air.

16. Atmosphere Troposphere - Most of the weather occurs. Stratosphere - 19% of the atmosphere’s gases are here; ozone layer is here Mesosphere - Most meteorites burn up here. Thermosphere - High energy rays from the sun are absorbed; hottest layer. Exosphere - Molecules from atmosphere escape into space; satellites orbit here.

19. Thunderstorms What type of cloud causes these? Consists of gusty winds, heavy rain and hail. Can result in a tornado Picture taken from: http://www.fairfield.k12.ct.us/Rogerludlowe/ crogerludlowe03/webquests/Weather/ thunderstorm.jpg
