  1. 1. T i d e s ! By Marin and McKenzie!
  2. 2. What are tides caused by? <ul><li>Tides are caused by the gravitational pull of the moon, sun and rotation of the earth. </li></ul><ul><li>The key to tides is the changing strength of the moon’s gravitational pull on different parts of the world. </li></ul><ul><li>The cause of the tides during the day is the moon’s orbit around the earth. </li></ul><ul><li>The moon pulls on the water closest to it, causing high tides and low tides. </li></ul><ul><li>When the sun, moon and earth form a straight line, we notice greater differences between the high and low tides. This is called a spring tide. </li></ul>
  3. 3. Different types of tides and there definitions <ul><li>SPRING TIDES: a spring tide is when the earth, moon and sun form a straight line. This causes greater differences between tides. </li></ul><ul><li>NEAP TIDES: a neap tide is when the earth, moon and sun form a right angle triangle. This causes smaller differences between tides. </li></ul><ul><li>HIGH TIDES: a high tide is when the moon is pulling the water from the closest part of the globe to it. This causes the water to rise. </li></ul><ul><li>LOW TIDES: a low tide is when the moon is not pulling the water from that certain part of the globe. This causes the water to fall. </li></ul>
  4. 4. Facts <ul><li>When there is a Full Moon or a New Moon, the gravitational pull on the earth is dramatically stronger so the high tides are higher and the low tides are lower. </li></ul><ul><li>Tides are exactly 12 hours apart, meaning if the low tide was at 4am the next low tide would be 4pm. </li></ul><ul><li>A low tide and a high tide are exactly 6 hours apart. </li></ul><ul><li>The moon has more effects on the tides then the sun because it is closer. </li></ul>
