Earth tide is the sub-meter motion of the Earth of about 12 hours or longer caused by Moon and Sun gravitation, also called body tide which is the largest contribution globally. Due to the cyclic rotation of the earth and moon, the tidal cycle is 24 hours and 52 minutes long. During this time, any point on the earth's surface experiences two high tides and two low tides. When the sun, moon, and the earth are lined up, the sun and moon are exerting their strongest force together and tidal ranges are at their maximum.

Scientist claim Tidal forces may have contributed to triggering the devastating magnitude 9.0 Sumatra earthquake of 2004 and other large earthquakes in the region. Also scientists are studying tidal ecosystems to understand how they might be affected by man made machinery.

The moon doesn't predict anything, but scientists do and the gravitational pull of the moon , sun, and the earth determines tidal movements.


Study of tides?

Oceanographers are scientists who study the tides. They record details such as the measurement of the heights, times and the extent of the rising and falling of tidal waters. This information is vital for the navigation of ships that rely on accurate data about the speed and direction of tidal currents.


What factors influence tidal patterns?

Tidal patterns are primarily influenced by the gravitational forces of the moon and the sun, as well as the shape and depth of the ocean basin. Other factors such as the Earth's rotation, wind patterns, and geographical features can also affect tidal patterns.

What is tidal and non tidal?

Tidal refers to phenomena related to the regular rise and fall of ocean water levels caused by gravitational forces from the moon and sun. Non-tidal refers to areas that are not influenced by these regular tidal patterns, such as lakes, rivers, and some groundwater systems.


How ocean basins affect tidal pattern?

Tidal patterns are greatly influenced by the size, shape, depth, and location of the ocean basin in which the tides occur.
