TidesThe Moon’s gravity tugs on the Earth.
It pulls the most on the part of the Earth that is closest to the Sun, which raises the atmosphere, the oceans, and even the rocks (a little)
It pulls the least on the part of Earth that’s farthest, which allows the oceans and atmosphere to be further from the Moon (and higher)
The Sun’s gravity does the same thing, but to a lesser extent
When the moon is new or full, the gravitational forces of the sun and moon are pulling at the same side of the earth. (See the diagram to the left.) This occurrence creates the extra large "spring" tides.
When the moon is at first and third quarter, the gravitational forces of the sun and moon are pulling at 90 degrees from each other. (see the diagram to the left.) This occurrence yields little net tides called neap tides.
How Tides Look on the Earth
Every twelve hours, you will have two high tides and two low tides.
