The tidal force or tide-generating force is a gravitational pull on a body, that differs throughout the gravitational field which the body is in. The different tidal forces at the different parts of a body cause the body to stretch more or less toward the gravitational pull, producing tidal phenomena in the body, such as two tidal bulges, on ...
The tides received relatively little attention in the civilizations around the Mediterranean Sea, as the tides there are relatively small, and the areas that experience tides do so unreliably. [3] [4] [5] A number of theories were advanced, however, from comparing the movements to breathing or blood flow to theories involving whirlpools or ...
In 1749 Richard Dunthorne confirmed Halley's suspicion after re-examining ancient records, and produced the first quantitative estimate for the size of this apparent effect: [3] a centurial rate of +10″ (arcseconds) in lunar longitude, which is a surprisingly accurate result for its time, not differing greatly from values assessed later, e.g ...

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.
In coastal areas, because the ocean tide is quite out of step with the Earth tide, at high ocean tide there is an excess of water above what would be the gravitational equilibrium level, and therefore the adjacent ground falls in response to the resulting differences in weight. At low tide there is a deficit of water and the ground rises.
This means that most atmospheric tides have periods of oscillation related to the 24-hour length of the solar day whereas ocean tides have periods of oscillation related both to the solar day as well as to the longer tidal lunar day (time between successive lunar transits) of about 24 hours 51 minutes.
The exact drop in temperature can vary widely based on other factors like cloud cover and the time of year. Time of year matters because the angle at which sunlight strikes the Earth affects ...
