The answer to this question is in the air the dance of two large objects and understanding gravity.

We will remember all the information again to the reasons let’s see.

Tides are primarily caused by the gravitational effect of the moon on the Earth.

As the moon orbits the Earth, its gravity pulls the oceans toward it sea ​​level rise happens. This effect is more pronounced at points where the moon is close to the earth and is also visible in these areas. “high tide” It has been said.

The moon has a similar effect on the other side of the Earth. gravity and this causes a rise on the other side of the oceans.

Does the sun have any effect?

In fact, the sun also has an effect on the tides, but this effect is not as pronounced as that of the moon. Sun, much bigger than the moon and is a powerful source of gravity, but the distance from Earth reduces the effect of this force.

The sun’s gravity spreads over a much larger area than the moon’s gravity, and so its pull on the oceans is less noticeable. The sun’s effect on the tides, “daily tides” It manifests itself in the form of smaller fluctuations, known as.

If we look at the numbers The sun is 27 million times larger than the moon. The gravitational force of the sun on the earth is 177 times greater than that of the moon on the earth. If there were only tides of comparable mass, the effect of the sun would be 27 million times more pronounced.

But here the sun relative to the earth relative to the moon 390 times further This must not be forgotten. This reduces the force required for the tide by 390³. Because of all these circumstances, the tidal force of the sun is on average half that of the moon.

The gravitational forces of the Moon and Sun can combine from time to time to create larger or smaller tides.

When the moon and the sun are in alignment, that is, during the new moon or full moon, “spring tide” Stronger tides are formed, called tides. This happens when the gravitational forces of two celestial bodies combine and pull the oceans even more towards them.

Similarly, when the moon and the sun form a right angle, “still tide” Weaker tides, called tides, appear.

Although the sun does not have as great an influence on the tides as the moon, sustainability of life is of vital importance.
