9 /26/13 23rd Day of School

1. 9/26/1323rd Day of School Learning Goal: I will be able to explain how the water cycle and atmospheric conditions relate to the weather patterns on Earth. Due Today: 1) Water cycle and humidity notes; Questions # 1,2 & 6 page A63. Evening Assignment: Study for Weather Patterns Quiz and Atmosphere Re-Test.

2. On a slip of paper write your name, date, and answer the following question: List in order the steps involved in cloud formation. When done, update your weather conditions chart. Do Now

3. Steps in cloud formation: • Sun heats water (liquid) and causes it to evaporate into water vapor (gas) • Warm moist air rises (gas), expands, and cools as it goes higher in altitude. • Water vapor (gas) in the air condenses into tiny droplets (liquid) or ice crystals (solid). • These droplets or ice crystals condense around tiny solid particles such as dust, smoke, and salt. How did you do? McDougall Textbook p. A60

4. Add today’s current weather conditions to your chart Core 1 Do Now Use wral.com for your weather source. Record the data for today.

5. Add today’s current weather conditions to your chart Core 2 Do Now Use wral.com for your weather source. Record the data for today.

6. Add today’s current weather conditions to your chart Core 3 Do Now Use wral.com for your weather source. Record the data for today.

7. Add today’s current weather conditions to your chart Core 4 Do Now Use wral.com for your weather source. Record the data for today.

8. Air moves from high pressure toward low pressure Temperature differences create… Air pressure differences which produce wind. How wind forms McDougall Text p. A48

9. Read the pages about the water cycle and precipitation. Summarize each section by writing at least 4 key points in bullet formatin your own words (don’t copy word-for-word from textbook.) Pages A 56-59 • Section 2.3 Most clouds form as air rises and cools. • Temperature affects water in the air. • Water in the Air • Humiditiy (only summarize the 1stparagragh) • Water vapor condenses and forms clouds. Summarizing McDougall Text p. A59
