Why do tides rise and fall?

Answer 1

The gravitational pull of the moon (and sun) pulls the world's oceans into a dome of water who's peak is closest to the source of the gravitational field. The dome is highest when the Sun and Moon are aligned with each other relative to the Earth. It is lowest when the Sun and Moon are on opposite sides of the Earth, hence the variation in Spring and Neap tides. As the Earth rotates, the land masses move relative to the dome of water, causing water levels at the shoreline to rise and fall. Strictly speaking the tide does not 'come in' and 'go out' horizontally - it rises and falls vertically. There is a popular misconception that all beaches are more dangerous on a falling tide - this isn't necessarily so. Local currents and wave conditions are more frequently governed by the shape and composition of the beach rather than any specific stage of the tide. Rip currents can (and do) form at any stage of the tide.

Answer 2

the way the moon is that night is the way the tied is going to be...... pink sky in morning sailer's sail morning pink sky at night sailer's sail night and that is the way the tied goes up or done

Answer 3

The gravitational pull of the moon moves the water twice a day.

Answer 4

the moons gravity p-ulls it in and out

Answer 5

the tides are controlled by the moon

Answer 6

by the moon
