Answer:
B. Global winds
C. Solar radiation
Step-by-step explanation:
Ocean current is can simply be define as water in motion and can be observed easily in oceans. When the global wind blows, it enforces the molecule sof water at the upper region of the ocen to move. This causes ocean current.
Solar radiation causes uneven heating (variation in temperature) of sections of the water, thus variation in density. This forces the molecules into motion.
