What is the primary reason for warm ocean currents being surface currents?

• Warm water has lower density than cold water.

• Warm water is pushed to the surface by ocean tides.

• Warm water has a higher salt content than cold water.

• The surface of the ocean loses heat to the air.

Why does the Moon, despite being smaller than the Sun, have a greater influence on Earth's tides?

• because the Moon is closer to Earth

• because the Moon is denser than the Sun

• because the Moon is solid, not gaseous

• because the Moon is more massive than the Sun
