Everyone knows that our ocean waters rise and fall at different times of the day. but have we ever wondered where the water goes
when this happens or even what causes the sea level to rise and fall. I know we might be thinking perhaps the weather but the weather
has nothing to do with tides. in fact it has been proven that the moon is the cause of tides; but what does the moon have to do with it?
the reason for this page is to help us find these answers in better explanation and better understanding.

Have you ever been sitting on the beach watching the waves and wondered to yourself, what causes these waves? Why we have different tides at different times of the day? Well, here that will all be explained for you.

  • The website was found and reviewed on May 4, 2009.
  • The intended audience is teachers,the general public and others who may be interested in this site would be curious minds.
Summary
The site was fairly easy to follow. It has the basic information about tides. The contents of the site focused solely on tides and how one can make predictions of when the tides would be at their highest or lowest. The site has experimental research for individuals who may be interested in learning about a more specify topic such as; Moon, phases of the moon, low or high Tides, etc . There is data provided which can be plotted onto a graph to determine the day and time of the high and low tides. At the top of the page, anyone browsing the site can “ask an expert” “project guides/ideas” or “compete in advance science competitions.
  • In my opinion, this website is educational for those who may want to further their understanding of tides and to be able to predict their high and low periods. It is a good site because it provides hands-on experiment.

Summary
  • The site gives the basic information on tides and shows diagrams. It is easy to follow and the diagrams are very helpful. It is set up with subtitles that are followed by information on that topic

This section provides links that illustrate how Tides are created, how we observe them, and how we know they exist. Tides are the periodic rise and fall of the ocean waters caused by gravitational pulls of the Moon and Sun (to a lesser extent), as well as the rotation of the Earth. Some well known Tides are Spring Tide, Neap Tide, and Lunar Tides. When the Sun, Earth and moon are in a straight line, this causes a Spring Tide. The spring tides create high tides that are very high and low tides that are really low. When the sun and the moon are the right angle of each other, this is called a Neap Tide. The neap tides create high tides that are very low and low tides that are very high. The sun also pulls at the Earth but, not as nearly as strong as the moon.

You may think that there is only one high tide at a time on Earth, but the truth is, that there is two different high tides on Earth at the same time. How is this possible? The tides come from the gravitational pull from the moon, and the centrifugal force to cause the high tide on the opposite side of the moon. The reason there is two high tides about every twelve hours is that you have a tide when closer to the moon, and then again when the moon is opposite from you.

A tide is from the sun and moons force. We have high tides and low tides. They rise up towards the coast, all fall back into the sea. The incoming tides are called flood tides. The tides going away are called an ebb current.


The Highest Tides

The moon gives a force to the earth, then the earth pushed closer to the moon. With that, the water is closest to the moon, which makes the tides bigger. The reason for the high tides on the opposite side of the earth are because the force that the earth is being pulled toward the moon, the tide gets held which pushes the tide to be bigger.
