______ and ______ determine the direction of ocean currrents.
What are prevailing winds and the position of continents?

What is...
climate
Ocean currents from the equator will have a ______ temperature.
What is higher/warmer/hotter?
narrow, strong “rivers” of wind, high in the troposphere, moved by high pressure to low pressure
What is...
jet streams
How does energy transfer on the planet?
What is...
the sun heats up the Earth's surface unevenly, direct sun on the equator, molecules become hotter which creates convection currents. These currents are moved because of the density of the molecules. The direct energy from the equator is distributed across the globe because of Ocean Currents which are pushed by wind currents.
the lines of latitude
Energy from the ______ is transferred to ______. Some of that energy is then transferred to the ______ above.
What is...
the Sun, Earth's surface, and the air
This powerful current starts near the equator and runs up the East Coast of the United States.
