Why do we have tides?

  • We have tides because of the sun and the moon!
  • They create a gravitational pull which makes tides on Earth.
  • Gravity is the source of our tides, distance and mass are the two forces that effect this force.
  • Earth's rotation effects tides because, were the earth is, will put into play where the tides will be high and low.
  • Tides occur twice a day, one high tide and one low tide!

Spring tides

What occurs when we have a spring tide?

  • I know what you're thinking! A spring tide occurs in spring but that my friend is not the answer!
  • In order for a spring tide to occur, the moon has to be at full moon or new moon, so a spring tide happens twice a month.
  • A spring tide is when the Earth, Sun, and Moon are all in a line.
  • A spring tide rises higher and falls lower than the average everyday tide.

neap tides

what occurs when we have a neap tide?

  • A neap tide is when the sun and the moon are at right angles to each other.
  • Neap tides only happen during the quarter moons.
  • They are relatively weak tides because they are being pulled from two different directions.
