Eighth Grade Week 14

As we continue our look at the Earth's oceans we now focus on movement besides currents. This week we will look at both waves and tides

How does a wave form?
What happens to a wave near shore?
What causes tides?

Contracts this week are Design Your Own.

    Waves are caused by differentiating wind speeds, underwater volcanic eruptions, earthquakes, and landslides.

    Are there different time lengths for tides? Like does each tide last for a different length of time or are they all the same?

    so if we don't get a tide on the opposite side of the Earth from the moon by leaving water behind how does it happen?

    Why do some places have two high tides and two low tides but other places along the coast don't have that many a day?

    tides are caused when the pull from gravity moving the waves causing it to be bigger
    this happens because i KNOW i heard this in class
    but yea, this happens because the bottem of the water is hitting the surface making it want to stop

    so as in example: wen people are walking and someone stops because of SOMETHING the other people behind THAT person stops because of THAT person in the front causing to have alot of people clumped together

    so as for water this makes a big hunk of water getting squished together making it higher because the water in the bottem is slowing down because its slowing down cus of the surface

    ebbottbaby,

    Here is an interesting map of tide movements.

    Now I wonder why the red dots on the map are where there are.

    it is important to learn about water and where it comes from because the eath is 75% water. Asking these questions give us more insite about the planet we live on and can probally (edvantually) answer questions about how the world began of will end.

    MELISSA

    WATER IS IMPORTANT BECAUSE WHEN 2012 COMES
    WE CAN PREDICT HOW FAST THE WATER GOES
    SO WE KNOW WEN THE CONTINENTS ARE GOING TO FLOOD
    AND BY THAT TIME WE WILL BE IN SPACE IN ANOTHER LIVING PLANET

    :D

    my last sentence is not true_)
