  1. 1. Tides By Emily and Nicole
  2. 2. How Tides are caused <ul><li>Roughly every 12 hours the ocean on each side of the globe rises a little and then falls back. </li></ul><ul><li>Tides are caused by the gravitational pull of the moon, sun and rotation of the earth. Which causes the ocean to rise and fall which is known as high tide and low tide. </li></ul>Gravitational pull is gravity pulling on the ocean
  3. 3. Different types of tides <ul><li>High tide (Common) </li></ul><ul><li>Low tide (Common) </li></ul><ul><li>Neap tide (Less Common) </li></ul><ul><li>Spring tide (Less Common) </li></ul>
  4. 4. High tides <ul><li>A high tide is only happening on opposite sides of the world at one time. It is caused by the gravity pulling up on that part of the ocean. There is less shore seen when a high tide is happening. </li></ul>
  5. 5. Low Tides <ul><li>At low tide you will see lots of the shore because the sea has gone a long way out . This is also caused by the gravity pushing down on that part of the ocean and can only happen on opposite sides of the world at one time. </li></ul>
  6. 6. Neap Tides <ul><li>When the moon is neither full or there is no moon at all, a Neap tide is occurring. Neap tides usually occur 6 hours between a low tide and a high tide. </li></ul>dictionary.com meaning of neap adjective 1.designating tides midway between spring tides that attain the least height.
  7. 7. Spring Tides <ul><li>When there is a full moon or a new moon the tidal range is the greatest. So if it is a Low tide and a Spring tide, you will see rocks and sand that are usually underwater at a normal Low tide. </li></ul>
  8. 8. Other Pictures When the Sun and Moon form a right angle, as when we see a half moon, their pulls fight each other and we notice a smaller difference between high and low tides. These are called neap tides. When the Moon, Earth, and Sun fall in a straight line, which we call syzygy ( siz -eh-gee), we notice the greatest difference between high and low tide water levels. These spring tides occur twice each month, during the full and new Moon. If the Moon is at perigee, the closest it approaches Earth in its orbit, the tides are especially high and low.
