  1. CRCT Question What is the most abundant salt in the ocean? • Hydrogen dioxide • Sodium Chloride • Calcium oxide • Sodium dioxide

  2. ATTENTION Ocean Test will be Tuesday January 31st

  3. Why is this important? How do currents affect us?!?

  4. Today’s Mission I facilitate with your questions/previous knowledge Tides, Waves, Currents Activities, Games, and Video Clips

  5. Part 1 “tag the text notes” What questions and comments do you want to add?

  6. Ocean Motions Waves – are pulses of energy that moves through the ocean. • Caused by wind blowing over long distances. Also affected by how long the wind has been blowing. • Deep water is not affected by wave motion as much as surface. Tides – are the daily rise and fall of the sea level along a coastline • They are caused by the gravitational pull of the moon and sun on the earth. • There are 2 high tides and 2 low tides every 24 hours • This means the tide goes from high to low in about 6 hours. • This also means that every there is a 12 hour time period between each high and low tide

  7. Seeing the earth, moon and sun effects Add image here

  8. Spring tides • Are tides that are especially high or low during a 24 hour period. • They are caused by the earth, moon, and sun lining up in a straight line and the pull on the oceans is especially strong. Neap tides • Tides that show very little change between high and low tide during a 24 hour period. • They are caused by the earth, moon, and sun forming a right angle and the pull on the oceans is weak

  9. Currents – an ocean current is a “river” of moving water with the ocean. Example – Atlantic Gulf Stream • The water in the current has the same properties and does not mix much with the rest of the ocean. • All ocean currents flow in predicable patterns • Surface currents, like waves, are driven and determined by wind and the Coriolis effect • Coriolis effect – the apparent curving of the path of a moving object from an otherwise straight path due to the Earth’s rotation. • Ocean currents can affect climate by warming or cooling the air above the current. Example – England is warmer than it should be based on its latitude because of the Gulf Stream current coming from the southern USA.

  10. Part 2 Surface vs. Deep What did you find out Watch It in Action!

  11. Major Points Surface • Caused by wind • Paths are deflected due to corealis effect Remember Corealis is the path of the currents due to the rotation of the Earth Deep • Caused by the change of density • Temperature and salinity effects the density • Caused from the polar ice caps
