Tides are periodic rises and falls 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.
Gravitational pull exerted by one object, such as the sun or moon, that raises tides on another object, such as the Earth., and tide. Rise and fall of the ocean’s waters, caused by the gravitational pull of the moon and sun.
Tides are caused by gravitational pull of the moon and the sun. The rise and fall of the tides play an important role in the natural world and can have a marked effect on maritime-related activities. The image aboves shows the NOAA San Francisco Tide Station, in operation for more than 150 years.
Another common inquiry is “What generates tides on the Earth?”.
Some believe that the forces that generate the tides are: The gravity force of the moon. This force moves the water in the oceans toward the moon. A point P at the rotating surface of the earth will experience a varying water depth with two maximum (two high tides).7.3. Spring tide – Neap tide.
Tides are the regular rise and fall of sea levels. The gravitational pull of the Moon and Sun causes the tides. Knowledge of the tides is essential to safely enjoy the seaside.
The next thing we wondered was: how are tides caused how often do they occur?
Spring tides occur twice each lunar month all year long, without regard to the season. Seven days after a spring tide, the sun and moon are at right angles to each other. When this happens, the bulge of the ocean caused by the sun partially cancels out the bulge of the ocean caused by the moon.

How do tides affect human existence?
Caused by actions of winds. Can be seen in any water bodies. Occurs many times a day. Horizontal movement of water molecules.
The ocean tides on earth are caused by both the moon’s gravity and the sun’s gravity. Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
What’s the difference between a tide and a current?
Difference Between Tides and Currents. Tides are big rise and fall of ocean water caused by the gravitational forces of the moon and sun. Currents are waves in ocean water caused by winds, temperature difference, and the topography of the bottom of the ocean surface. Waves move from side to side that can be left to right or right to left whereas tides move up and down.
