Q

how does this energy impact ocean currents?

A

energy from winds is transferred by friction to ocean currents

(wind has energy bc moving, causes friction on ocean surface as wind pushes water == CREATES CURRENT

how does the shape of land masses affect ocean currents?

A

they deflect the movement of current (divert them another direction)
