When you see the tide roll in or out, what you’re really seeing is a cycle of small changes to the distribution of our planet’s oceans. As the Moon’s gravity tugs at Earth, it shifts Earth’s mass, distorting its shape ever so slightly into that of a football ― elongated at the equator and shortened at the poles.

19 Οκτ 2024 · Tide, any of the cyclic deformations of one astronomical body caused by the gravitational forces exerted by others. 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.
5 Αυγ 2021 · Rising and ebbing tides happen as Earth’s landmasses rotate through the tidal bulges created by the Moon’s gravitational pull. Our observer sees the tides rise when passing through the bulges, and fall when passing through the low points.
Tidal cycles promote water-mass transfers between the two interlinked basins and a variety of associate hydrodynamic processes (e.g. turbulences, compensational flows, vortexes, etc. From: Regional Geology and Tectonics (Second Edition), 2020
Three basic tidal patterns occur along the Earth’s major shorelines. In general, most areas have two high tides and two low tides each day. When the two highs and the two lows are about the same height, the pattern is called a semi-daily or semidiurnal tide.
19 Οκτ 2023 · kinetic energy produced by the movement of air, able to be converted to mechanical power. The regular rise and fall of the ocean’s waters are known as tides. Along coasts, the water slowly rises up over the shore and then slowly falls back again.
Information resource on tides, including the spring-neap cycle, diurnal and semi diurnal tides, tidal range and the King tide.
