Question

1pt what is the primary cause of ocean waves?
a. upwellings
b. wind
c. density differences in ocean water
d. temperature differences in ocean water

Explanation:

To determine the primary cause of ocean waves, we analyze each option:

• Option A: Upwellings involve the upward movement of deep - ocean water and are not the main cause of ocean waves.
• Option B: Wind blowing over the ocean surface transfers energy to the water, creating most of the ocean waves we observe. This is the primary cause.
• Option C: Density differences in ocean water mainly drive ocean currents like thermohaline circulation, not the formation of ocean waves.
• Option D: Temperature differences in ocean water are related to density differences and ocean currents, not the primary cause of ocean waves.

Answer:

B. wind
