Question

what causes tides? a. density differences in ocean water b. heat from the sun, which causes winds c. underwater earthquakes, volcanic eruptions, or landslides d. the gravitational pull of the moon on the water at earth’s surface

Explanation:

Density differences drive ocean currents, not tides. Solar heat and winds cause surface currents, not tides. Underwater geological events create tsunamis, not tides. Tides are primarily caused by the moon's gravitational pull on Earth's ocean water, with a smaller contribution from the sun.

Answer:

D. The gravitational pull of the moon on the water at Earth's surface
