What causes tides. Ocean tides are primarily caused by the gravitational pull of the Moon and, to a lesser extent, the Sun, on Earth’s waters. Jun 15, 2025 · Tides are the rhythmic rise and fall of sea levels, a phenomenon primarily caused by the gravitational forces exerted by the Moon and the Sun on the Earth, as well as the Earth’s own rotation. The most familiar are the periodic variations in sea level on Earth that correspond to changes in the relative positions of the Moon and the Sun. Study with Quizlet and memorize flashcards containing terms like What causes the seasons?, earth's axis, high tide and more.

Find out how the sun, the continents and other factors affect the tides' size and frequency. Red Tides: Two Different Organisms When most people search for “what causes red algae,” they’re usually thinking about the dramatic reddish-brown discoloration that appears in coastal waters, commonly called a red tide. This rise in water level can cause extreme flooding in coastal areas, particularly when storm surge coincides with normal high tide, resulting in storm tides reaching up to 20 feet or more in some cases. Storm tide is the water level rise due to the combination of storm surge and the astronomical tide.

Learn how gravity, the sun and the moon, and the Earth's rotation create tides. When this happens, the bulge of the ocean caused by the sun partially cancels out the bulge of the ocean caused by the moon. Tides are a cycle of small changes in the distribution of Earth's oceans. Other factors include the Earth’s rotation, the Moon’s orbit, the presence of continents on Earth, variations in water depth, and the inertia of the water.
