Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth.
The times and amplitude of tides at a locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing). Some shorelines experience a semi-diurnal tide - two nearly equal high and low tides each day. Other locations experience a diurnal tide - only one high and low tide each day. A "mixed tide"; two uneven tides a day, or one high and one low, is also possible.
Tides vary on timescales ranging from hours to years due to a number of factors. To make accurate records, tide gauges at fixed stations measure the water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called mean sea level.
Most people are already familiar with the idea of high and low tides, but where do they come from? What causes this movement and why does it occur with such regularity? Tune in as Josh demystifies the rise and fall of the sea.

It's because your mental picture of the tides is probably WRONG!!! Join Gabe on this week’s episode of PBS Space Time as he sets the record straight on tidal force, gravitational differential and what role the moon actually plays in tides. Why don't lakes have tides...
A video lesson. How the Sun and Moon cause tides. Spring tides, neap tides, and the three patterns of tides on earth caused by the rotation of Earth and local topographical features: Diurnal, Semi-Diurnal and Mixed tides.
The video explains how high tide and low tide occurs on earth. It shows how moon influences tides on earth.

Tide - ज्वार-भाटा - Hindi Documentary Video, low tide | high tide Science Educational video why tides occur. What are tides and moon. Moon effect on earth Hindi Film.
Come storm, come fire, we stride in thunder.
Sea torn asunder now wears the crown
Lust, loneliness, unearthed rejection
Soul resurrection in forms unknown
New field swept off the stains of time
On a course to a destination
Earthbound yet undetainable,
defiant to ride with the tide
Soulflight to a realm beneath the soil
Soulflight!
Do you deserve a compensation?
Lost hope in a maelstrom
Still drifting with the tide
Faint recollection, beconing disaster
Obey the master who sings of doom
Asured demise but who`s going under
Possessed to plunder the virtue in truth
New field swept off the stains of time
On a course to a destination
Earthbound yet undetainable,
defiant to ride with the tide
Soulflight to a realm beneath the soil
Soulflight!
Do you deserve a compensation?
Lost hope in a maelstrom
Still drifting with the tide
Come storm, come fire, we stride in thunder
Sea torn asunder now wears the crown
New field swept off the stains of time
On a course to a destination
Earthbound yet undetainable,
defiant to ride with the tide
Soulflight to a realm beneath the soil
Soulflight!
Do you deserve a compensation?
Lost hope in a maelstrom
