  • This is something that everybody learns in the schools.
    But they take time to learn this. I am sure they will learn it in a shorter period if they will be taught with the help of this colorful presentation.

The Water Cycle and Weather

  1. 1. Water Cycle and Weather Ms. Mercer – Fifth Grade – Nicholas Elementary
  2. 2. Water Cycle and Systems 1. Water Cycle and Systems 2. Weather and Meteorology
  3. 3. Water on Earth
  4. 4. Is this enough water for a thirsty world?
  5. 5. Water Cycle Diagram Vapor Liquid Solid temperature causes water to change its physical state hotter
  6. 6. The Parts of the Water Cycle Evaporation Condensation Precipitation Mist Steam Fog Clouds Rain Snow Sleet Hail
  7. 7. How does water come back? Water Vapor from Clouds returns to Earth as: Snow Hail Rain Sleet
  8. 8. Physical Properties of H 2 O Vapor Liquid Solid Mist Fog Clouds Liquid Water Rain Snow Sleet Hail Ice
  9. 9. Parts of Weather Wind Temperature Caused by the amount of sunlight and the oceans and other large bodies of water Water Pressure Most water in weather systems comes from the oceans of the Earth The lower the pres-sure, the more water, air can hold. The higher, the less water Caused by air masses of different temperature running into each other
  10. 10. Parts of Weather Sun Fronts Warm air rises, cold air drops. Water Pressure Water lowers the temperature of the air above it. Low pressure causes clouds which can block the sun and heat Different areas get different amounts of sunlight; leading to a different air temperature
  11. 11. What makes weather? Water Fronts meet Results: Warm air moves up, while cold air moves down. When two masses meet the cold air will sink, and push the warm air up and over it Water will make cooler air, which meets warmer air over land, pushing it up. This can cause air to move (wind), or when warm air is pushed up over a cold front, it causes storms
  12. 12. Weather Maps Pressure H = High L = Low Fronts Cold Warm Weather Maps show areas of high and low pressure, cold and warm air (or fronts), and what direction they are moving.   
  13. 13. Onshore weather pattern 1. Cooler air over water is “pulled” toward the land. 2. The cool air “pushes” warmer air over the land, up and over the cold air mass. 3. The warm air cools, moving back down.
