8.10A- Convection & The Wind
A continuation of our learning about convection.
Do Now
Happy Wednesday! Your task is to silently and independently complete the Review Questions.
Hint: The horizontal paper with questions about balancing equations. Use your NOTES and the BOOK.
IF YOU FINISH EARLY, work on a station that you need to complete, but do NOT talk.
"What are we doing today, Ms. CJ?"
Well, since you asked... ;-)
- Do Now- Check!
- Hypothesis Foldable
- "Why Does Air Move?" Mini Lab
- Notes on Convection and the Wind
- Sea Breeze vs Land Breeze
- Practice
- Clean Up and Closing
Announcements!
- 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
- Wind
- 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)
Wind
- The movement of air from areas of high pressure to low pressure
- Wind is basically convection of the air because there is movement.
Global Wind Belts & Prevailing Winds
- Global wind belts influence climate and weather on Earth
- There are 3 types of prevailing winds
- Polar Easterlies
- Westerlies
- Trade Winds
Coriolis Effect
- Earth's rotation causes moving air and water to appear to be moving to the: right (Northern Hemisphere) OR the left (Southern Hemisphere)
Jet Stream
- Near the top of the troposphere (1st layer in atmosphere) is a narrwo band of high winds
- incluence weather as they move cold air from the poles toward the tropics and warm air from the tropics towards the poles
Local Winds
There are two main types
- Sea Breeze
- Land Breeze
Sea Breeze & Land Breeze
5 minute science Land and sea Breezes
Practice
We will be working on the foldables we have remaining:
- 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?
Please make sure to have it stapled, prior to turning it in.
