The East Australian Current _____ flow along the East coast of Australia, obviously.
Dose
Surface currents greatly affect the ______ in many parts of the world.
Climate
Ocean water gets ______ when it becomes saltier or gets colder. Cold air chills the water molecules at the surface, causing them to move closer together.
Denser!
A wave is defined as a transfer _______. Ocean waves are called mechanical waves because they travel through a medium. The ________, in this case, is water. The water doesn't actually travel with the wave, but only moves up and down. It's the energy that travels with the wave.
Energy, medium
