What causes tides in the oceans?
- Earth's rotation
- Gravitational pull of Moon and Sun
- Wind patterns
- Ocean currents
Answer: Gravitational pull of Moon and Sun
Tides are primarily caused by the gravitational pull of the Moon and, to a lesser extent, the Sun on Earth's oceans. When the Sun, Moon, and Earth align (full/new moon), spring tides occur with higher high tides. Neap tides occur when they are at right angles.
