What phenomenon occurs due to the gravitational pull of the Moon on the oceans?

Tides occur due to the gravitational pull of the Moon on the Earth's oceans. The Moon's gravity exerts a force on the water, creating bulges in the ocean's surface. These bulges correspond to high tides, while areas between the bulges experience low tides. As the Earth rotates, different areas move in and out of the bulges, resulting in the cyclical rise and fall of sea levels known as tides. This gravitational interaction is more pronounced than other factors like winds or atmospheric pressure in the context of tidal changes in the ocean.
