Tides have caused a lot of trouble recently. During high tide periods, low-lying areas that border the ocean now flood way more often than they used to. Between 2000 and 2017, the average frequency of "high tide flooding" across the United States increased by 50 percent. Floods of this sort block ...
Tides are caused by the gravitational pull of the Sun and the Moon on the Earth's surface. While most people associate them specifically with the ocean, the entire planet is subject to tidal forces, as is the atmosphere, and in fact all celestial bodies are influenced by these forces.
The key to understanding how the tides work is understanding the relationship between the motion of our planet and the Moon and Sun. As the Earth spins on its own axis, ocean water is kept at equal levels around the planet by the Earth's gravity pulling inward and centrifugal force pushing outward.
Low tide at the same fishing port in Bay of Fundy, 1972. Schematic of the lunar portion of Earth's tides, showing (exaggerated) high tides at the sublunar point and its antipode for the hypothetical case of an ocean of constant depth without land. There would also be smaller, superimposed bulges on the sides facing toward and away from the Sun.
Tides also occur as two high tides and two low tides each day, known as semi-diurnal. But they do not take place at the same time each day, because as mentioned, the moon takes slightly longer than 24 hours to line up again exactly with the same point on earth.

How do ocean tides work? the moon and sun pull the water causing tides. spring tides are stronger and happen when the sun and moon are either in the same direction or oposite each other. Neap ...
Anyone who lives close to ocean is familiar with the tides. And you probably know they have something to do with the Moon. But how do the tides work? Do other planets experience tides? Just what ...
