8.10A- Convection & Oceans

Happy Thursday, Mighty Meteorologists!

Do Now

  • Homework needs to be STAPLED and placed by the EDGE of your tables in a NEAT stack.
  • Complete the "Test Prep Thursday" activity... Worksheet with Multiple-choice Questions
  • This is a SILENT and INDEPENDENT activity.


  • Make sure you finished the foldables from class yesterday.

"What are we doing today, Ms. CJ?"

Well, since you asked... :-)

  • Test Prep Thursday / Do Now- check!
  • Sea Breeze vs Land Breeze Graphic Organizer
  • Notes on Ocean Currents
  • Station Rotation- Air & Ocean Currents
  • Clean Up and Closing


  • You will NOT have a quiz tomorrow. It has been pushed until WEDNESDAY.
  • Your TRIANGLES are due TOMORROW.
  • There are NO Saturday tutorials this week, school-wide. Enjoy your three-day weekends!
  • Remember to work purposefully and with URGENCY as we go through our stations.
  • Today is my sorority's 107's birthday!! Yay!

Ocean Currents Notes

Yes, of COURSE, Cornell Notes style!!

INB page 205 (yes, we are skipping for a reason)

: 8.10A- Ocean Currents

Essential Question: How does solar energy affect ocean currents? How do ocean currents affect weather and climate?

Main Ideas (left side)

Hint: spread them out a little bit.

  • What is an ocean current?
  • Types of Ocean Currents
  • Impacts on Weather and Climate

Leave space for the summary!!

What is an ocean current?

An ocean current is a large volume of water flowing in a certain direction.

Warm ocean currents originate (begin) at the equator.

Cold ocean currents originate (begin) at the Poles (either North or South).

Types Of Ocean Currents

Surface Currents

  • carry warm or cold water HORIZONTALLY across the ocean's SURFACE
  • they are influenced by wind belts (ex: trade winds blow warm water from Africa towards South America)


  • CIRCULAR system of currents
  • currents within gyres move in the SAME direction
  • Gyres in Northern Hemisphere move clockwise; gyres in Southern Hemisphere move counterclockwise


  • vertical movement of water toward's ocean surface (it goes UP)

Density currents

  • move water downward
  • NOT caused by wind; cause by change in density

Impacts on Weather and Climate

  • Solar energy drives CONVECTION in the oceans cause warm-and cold-water gyres
  • regions near warm-water currents are often warmer than regions near cold-water currents
  • The Gulf Stream is a surface current that affects states like Texas and brings heat and rain (Have you ever heard them mention the Gulf Stream on the weather report?)
  • The GREAT OCEAN CONVEYOR BELT affects weather and climate by circulates thermal energy throughout the Earth.
