Tides are the periodic rise and fall of the ocean waters. They are caused by the gravitational pulls of the Moon and (to a lesser extent) Sun, as well as the rotation of the Earth.
The Sun and Moon pull on the Earth, the water, even you! But gravitational attraction depends on distance and mass. For example, you have very little mass and you're very close to the Earth, so the Sun and Moon can't just yank you off the planet. The Sun is extremely massive, but it is an average of 93 million miles (150 million km) from Earth, compared with about 238,866 miles (384,400 km) from here to the Moon. And since the Moon is nearly 400 times closer to our planet, its influence on our oceans is twice as strong as the Sun's.
The key to tides is the varying strength of the Moon's gravitational pull on different parts of the globe. The Moon pulls most on the water nearest to it, creating a high tide bulge of water. On the opposite side of the planet, about 7,926 miles (1,2760 km) away, the Moon's pull is much weaker and the water is left to form another high tide bulge. Low tides are found halfway between the highs. The rotating Earth carries us through these regions of high and low water.
Within a small body of liquid, such as a pond or bowl of soup, there are no tides because the whole body of water is the same distance from the Moon, feeling an equal gravitational pull.
The timing of tides is determined by the Earth's rotation and the Moon's orbit around the Earth. As the Earth rotates once about its axis in 24 hours, the Moon is moving 1/30th of the way around in its orbit. It takes a given location on Earth about 50 minutes to "catch up with" the orbiting Moon, so a particular tide returns in approximately 24 hours and 50 minutes.
Well, the gravitational pull is an effect so if a body of water on Earth is closer to the moon, the tidal waves are higher than on the opposite side of the world. Hope that helps!
Yes. Think in terms of Newton's second law. Earth does produce a tidal effect on the Moon.
Yes. The effect of this is seen on tidal water. Tidal water is a "wave" following the moon around the earth as the moon moves.
The moon has an effct on our tidal system which thereafter has an effect on the ecosystem
Tidal Moon was created in 1938-12.

Yes, even if you cannot see the moon, it is still having tidal effect AND the sun also creates a tidal effect, weaker than the moon, but still there.
The moon's gravitation pulls water masses to cause the tidal effect.

The primary source of tidal effects on Earth is the Moon, and the Sun is #2.
The gravitational pull of the Sun and the Moon cause the tidal bulges.
Tides are fluctuations in the height of bodies of water due to the gravitational effect of the moon. The water is high when the moon is directly overhead or on the other side of the world and low when the moon is on the horizon. This effect can be greater or lesser depending on whether the sun's gravitational effect is added to that of the moon. At full moon and new moon, when the moon is lined up with the sun, the tidal effect is at its greatest. This is called spring tide. But at the quarters the sun's gravity counteracts that of the moon and the tidal effect is less. This is called neap tide.
None, its the other way around: The Moon influences the tides on Earth

The tidal effect of a body increases as a cube of the distance.
