Sailboats can travel around the world without having engines. They may use wind and large streams of moving water that flow through the oceans. These fast-moving ocean ____ help the sailboats to speed up their travel time.

The size of waves in the ocean is NOT affected by which of the following

Ocean currents curve in different directions due to the rotation of Earth on its axis. In the Northern Hemisphere currents curve to the right (clockwise) and in the Southern Hemisphere currents curve to the left (counterclockwise). This phenomenon is caused by the ____.

What causes cold, deep currents to begin moving in the oceans near the poles?

Which ocean water movement may intensify during windy storms as energy is transferred from the wind through the water?

In the Pacific Ocean, off the west coast of South America, many people depend on fishing for food and jobs.
