Tide
Tidal forces cause orbits to go to a state of lowest energy while conserving angular momentum. This results in the circularization of originally elliptical orbits. The ocean tide on earth from moon is

When a New Moon aligns with perigee, the next New Moon returns sooner than 29 days 12 hours and 44 minutes later, the mean period between successive New Moons.

tide(s): the divisions of a day used in the Anglo-Saxon period. The time from sunrise to sunset was divided into four tides or time periods. See Appendix II for the names of the tides.

The phenomena of varying coastal water levels, caused by the gravitational pull of the Moon and the Sun.

neap tide: Ocean tide of low amplitude occurring at first- and third-quarter moon.

Neap Tide - An unusually low high tide and unusually high low tide that occur when the tidal forces of the Sun and Moon act at right angles to one another ...

TIDAL(TIDE-GENERATING) FORCE - Differential gravitational force arising because the gravitational force exerted on one body by a second body is not constant across its diameter.

TIDE
A tide is a periodic rise and fall of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon.

Tide should be the most well known phenomenon due to the Moon. (Werewolves not counted.) From the figure below, we can see that the Moon exerts a stronger attractive force on the water in the near side of the Earth, ...

HIGH TIDE
High tide is the time of high water. High tides occur when the gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon.

Thomson's tide-predicting machine
Thomson was an enthusiastic yachtsman, his interest in all things relating to the sea perhaps arising, or at any rate fostered, from his experiences on the Agamemnon and the Great Eastern.

thermal tide A variation in atmospheric pressure due to the daily differential heating of the atmosphere by the sun; so-called in analogy to the conventional gravitational tide. See solar atmospheric tide.

Out With the Tide We have a word for things that move farther from Earth: up. The Moon is steadily moving up and up. As anyone who climbs long flights of stairs knows, it takes energy to move up.

earth tide (NASA SP-7, 1965) A periodic movement of the earth's crust caused by the tide-producing forces of the moon and sun.

spring tide tide that has a large change between low and high tide. It occurs at new and full phase, when the Moon's tidal effect is aligned with the Sun's tidal effect.

The height of the tide at any one place is determined by the shape of the coastline and of the nearby continental shelf. The presence of shelving land masses and bays gives much greater range to the tides than is seen in mid-ocean.

So, the highest tide occurs when the Moon is directly overhead.
Ah, well it would be if not for two complications.
First, the tidal "bulge" cannot keep up with the Earth's rotation.

A tidal bulge (called an equilibrium tide) does not really exist on Earth because the continents break up the tide when they pass under the Moon.

Like others of the "RS CVn" class, the two stars of Lambda interact tidally (a tide being a gravitational stretching effect) to affect each others' rotations.

If his theory were correct, there would be only one high tide per day at noon. Galileo and his contemporaries were aware of this inadequacy because there are two daily high tides at Venice instead of one, and they travel around the clock.

The tide results from the sun and comets being different distances from these massive amounts of matter.

This bulge is the high tide. In fact the moon causes the oceans to bulge in two places, the oceans facing the moon and the oceans facing away from the moon.

The tide of the ocean is well known; less well-known but equally real is the tidal distortion of the entire planet --- the continents (and everything underneath) are deformed daily by the tidal force (of the Sun and the Moon), ...

But, suppose the tide to be rising. Then, by continued observation, extended over an hour or more, it will be found that, in the general average, the ship is gradually rising, so that two different kinds of motion are superimposed on each other.

Go to a sporting goods store and get a tide table; many stores near the ocean provide them free. Choose a month and plot the height of one high and one low tide versus the day of the month.

With the rising tide of anti-Semitism in Berlin, Einstein was castigated for his "Bolshevism in physics," and the fury against him in right-wing circles grew when he began publicly to support the Zionist movement.

For my work on sea level change, I analyzed tide and weather data from the last 100 years and attempted to correlate flooding events with meteorological conditions.

structures called stromatolites -- larger low-tide field image.

This wobbling stretches and bends Io by as much as 100 meters (a 100 meter tide!) and generates heat the same way a coat hanger heats up when bent back and forth. (Lacking another body to perturb it, the Moon is not heated by Earth in this way.) ...

same was thought to apply to short period comets from the inner Oort cloud too. But it turns out that some comets can slip past the safety barrier of Jupiter and Saturn without the aid of a passing star, instead influenced by the Milky Way's "tide".

moon that it hardly moves at all, and the rock is so rigid that it hardly deforms at all; however, the water flows much more easily. Because of the pull from the moon on Earth's water, the water forms a bulge on the moon-ward side. This is high tide.
