Tides are the regular rise and fall of the ocean's surface that occur twice per day, resulting from gravitational interaction between the Earth, Moon and Sun.
Tides occur due to the gravitational pull of the Moon and the Sun on the Earth's ocean. When the gravitational force of the Moon is greater on one side of the Earth, it causes a bulge in the ocean water, which results in high tide. As the Earth completes a rotation, the bulge moves along with it, and low tide occurs when the ocean water equalizes across the Earth's surface.
Tides are important for several reasons. They help to regulate the Earth's climate, influence marine ecosystems, and impact coastal communities and industries. Tides also help to transport nutrients and sediments along the coast and contribute to the erosion and formation of shorelines. Additionally, tides provide a source of renewable energy through the use of tidal turbines.
