Earth tide (also known as solid-Earth tide, crustal tide, body tide, bodily tide or land tide) is the displacement of the solid earth's surface caused by the gravity of the Moon and Sun. Its main component has meter-level amplitude at periods of about 12 hours and longer.
For example, the lunar tidal acceleration at the Earth's surface along the Moon–Earth axis is about 1.1 × 10 −7 g, while the solar tidal acceleration at the Earth's surface along the Sun–Earth axis is about 0.52 × 10 −7 g, where g is the gravitational acceleration at the Earth's surface. Hence the tide-raising force (acceleration) due ...
When Venus is closest to Earth, its effect is 0.000113 times the solar effect. [50] At other times, Jupiter or Mars may have the most effect. The lunar gravity residual field at the Earth's surface is known as the tide-generating force. This is the primary mechanism that drives tidal action and explains two simultaneous tidal bulges; Earth's ...
High and low tide in the Bay of Fundy. The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
As you might expect, the moon is involved. But we’ve made it worse.
Munk & Wunsch (1998) estimated that Earth experiences 3.7 TW (0.0073 W/m 2) of tidal heating, of which 95% (3.5 TW or 0.0069 W/m 2) is associated with ocean tides and 5% (0.2 TW or 0.0004 W/m 2) is associated with Earth tides, with 3.2 TW being due to tidal interactions with the Moon and 0.5 TW being due to tidal interactions with the Sun. [3] Egbert & Ray (2001) confirmed that overall ...
The high tides are predicted to happen at South Florida’s coastline starting Tuesday morning, the city of Fort Lauderdale alerted. King tides might cause more flooding in Fort Lauderdale. Here ...
