SURFACE CURRENTS VS. DEEP OCEAN CURRENTS
COFFEE HOUR 1. one round of rocks paper scissors 2. loser: describe how surface currents move (start sentence with “In surface currents, water moves...”) winner: describe how deep ocean currents move (start sentence with “in deep ocean currents, water moves...”)
What causes deep ocean currents to move vertically (up and down)?
ANIMATION: HOT WATER AND COLD WATER → Reminder: density is basically how tightly packed together the molecules are! → dia/chapter3/lesson6#cold_and_hot_water dia/chapter3/lesson6#cold_and_hot_water → Remember: water molecules want to snuggle together when they're cold!
