Question

Surface currents and waves are powered by A) wind and heat. B) wind and tides. C) boats and wind. D) heat and weather.

Answer 1

For A and D the heat has very small effect on the currents. For C it makes no since because there is no boat that can change a whole ocean's current. Do I think it is B.

Answer 2

Answer;

B) wind and tides.

Explanation;

• Waves on the surface of the oceans occur as a result of energy passing through water. They are commonly caused by wind as a result of friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
• Surface waves and currents may also be caused by the gravitational pull of the sun and the moon on earth. Such waves caused by the gravitational pull of the sun and the moon are called tidal waves or tides.
