    circulation cells
    1. hot air rises= ⬇️ pressure_ air ÷, cools & moves to Hadley_ cool air sinks @ 30° of Equ=⬆️
    2. some cool air move back -> equ as trade winds_ rest travels to Poles= lower pt of Ferrel
    3. @ 60° N&S, hot air of Ferrel meet cold Polar_ hot air ⬆️ cr8ing polar & cools n sinks= ⬆️ pressure

    oceanic circulation

    ocean currents transfer HEAT ENERGY from area of SURPLUS (Equator) to DEFICIT (Poles)
    • wind driven surface currents & deep ocean currents move warm water to poles and cold to equator
    • @ arctic & antarctic, water v cold & dense so it sinks
    • warm water from equator replaces this surface water = ocean currents
    • cooled water flows back to equator = cold currents
