Why do you have tide?

When the earth rotates, it has the gravitational pull like o the earth and so does the Sun. When the Sun and the moon pull at the same time they make it bulge out on both sides. The way i remember it is when you squish a rubber band and it comes out on both sides evenly, it does the same thing as the Earth does. Also, wherever the moon is, is where you will have high tide because its where the biggest bulge is. You will also have high tide on the opposite side because of the Sun. The other sides is where there is low tide.

Example: When the Sun, moon and Earth are all in a straight line, high tides would be where the moon and Sun is (on the sides) and the low tides would be on the top and bottom.

normally tides are caused due to the gravitational forces put upon on the earth by the moon and the sun,and hence we have low and high tides based on the forces applied on the earth..by the moon and the sun.

The moon orbits the earth because of the gravitational attraction. But the sea between the earth's centre of gravity and the moon is slightly closer so the moon's pull on the water causes it to move towards the moon causing a high tide. Equally on the opposite side of the earth, the moon's pull is slighly less so that the water bulges out away from the moon and you have a high tide there as well. So you get 2 high tides every 24 hours as the earth spins beneath the moon, with the tides always in line with the moon's direction as the solid continents sweep around. There is a weaker effect due to the Sun, but the sun is so far away that the difference in pull between the two opposits sides of the earth is less, and the solar tides are weaker.
