8.10A- Convection & The Wind
A continuation of our learning about convection.
- Word Triangles are due on FRIDAY! NO EXCUSES!!!!
- Please buy LIQUID GLUE, and THANK YOU to those of you who have already done so! :-)
- We will be changing up the stations for tomorrow-Friday, so if you did not complete at least TEN, I suggest you come visit me during lunch / after-school.

"Why does air move?" Mini Lab, Textbook page 415
We were going to go outside today, but since it's freezing, as you complete your notes you may either work with a self-selected partner / listen to music on your own headphones.
Time for some Notes!
Convection & Wind!
Set Up your Notes Cornell Notes style!
Topic: 8.10A- Convection & Air Currents
Essential Question: How does uneven heating of Earth's surface result in air movement? How does the Sun's energy affect AIR on Earth?
Main Ideas (left side) Remember, you may also highlight in your book to assist you.
- Unequal Heating of Earth's Surface
- Global Wind Belts & Prevailing Winds
- Coriolis Effect
- Jet Streams
- Local Winds
Leave space for the SUMMARY at the bottom.
Unequal Heating of Earth's Surface
- The Sun's energy warms Earth, but due to Earth's tilt, all areas do not receive the same amount of sunlight.
- Areas by the equator receive direct sunlight nearly year-round
- Tropics get more sunlight; areas by the poles get less
- Differences in density cause warm air to rise and cooler air to sink (aka convection)
Global Wind Belts & Prevailing Winds
- Global wind belts influence climate and weather on Earth
- There are 3 types of prevailing winds
- Polar Easterlies
- Trade Winds
- Earth's rotation causes moving air and water to appear to be moving to the: right (Northern Hemisphere) OR the left (Southern Hemisphere)
- Sea Breeze
- Land Breeze
- Air Mass
- Sea Breeze vs Land Breeze
Exit Ticket, Clean Up, & Closing
On a POST-IT, answer the following questions. Do not forget your NAME.
- What is the difference between a sea and land breeze?
Describe the Coriolis effect.
How does convection affect our atmosphere?
Your HOMEWORK is textbook pages 91-93, and 421.
