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.
What else can I help you with?
What is the alternate rise and fall in the level of sea water?
The rise and fall is the tides.
The rise and fall of ocean water are called?
Tides are the rise and fall of ocean water. They are the combined effects of the gravitational forces exerted by the sun and moon on the rotation of the Earth.
When boating on coastal waters it is important to be aware of the tides. Why?
Tides cause water levels to rise and fall.
How often in 24 hours does the tide rise and fall?
Tides typically rise and fall twice in a 24-hour period. This cycle of two high tides and two low tides is known as a semidiurnal tide pattern.
The periodic daily rise and fall of ocean water?
The periodic rise and fall of ocean water is known as the tidal cycle. It is caused by gravitational forces exerted by the moon and the sun on the Earth's ocean water, resulting in bulges of water that move around the planet as the Earth rotates. Tides typically occur twice a day, causing high tide and low tide.
