How does a tide occur
WebTides are the alternating rise and fall of the sea surface. They are due mainly to the gravitational attraction (pull) of the moon and sun on the rotating earth.

WebApr 13, 2024 · As Earth rotates, the locations of high and low tides change, causing the ocean to move back and forth. In addition to the moon’s gravity and Earth’s rotation, the sun’s gravity also impacts Earth’s tides. When the moon happens to line up with the sun relative to Earth, their combined gravitational pull creates extra-high tides.
