Lesson 92 * Teacher PrepStandard & Objective: S1 O3a Model energy flow in the physical dynamics of oceans (e.g., wave action, deep ocean tides circulation, surface currents, land and sea breezes, El Nino, upwellings.

Materials: Xerox Assignment 3, and 50 copies of the Tracing page that goes with this copy.

Self Starter * 40 Points * 2/20/2014 * Lesson 92Today’s Learning Objective and Questions

• Today’s Learning Objective: Students will learn how spring and neap tides form.

• Essential Question: Describe an El Nino Current.

• Answer: Warm air moves from the land over the ocean. This warm air causes cold nutrient rich water to move up from the bottom of the ocean.

Spring Tides and Neap Tides * Student Read

• The sun’s gravity also pulls on Earth and its oceans. However, even though the sun is much larger than the moon, the pull of the sun’s gravity isn’t as great.

• That’s because the sun is much farther away. The sun just strengthens or weakens the moon’s influence on tides.

• The Figure on the next slide shows the position of the moon relative to the sun at different times during the month. This position determines how the sun affects tides. It creates either spring tides or neap tides.

The sun and moon both affect Earth

High and low tides are due mainly to the pull of the moon

Spring Tides

• Spring tides occur during the new moon and full moon. The sun and moon are in a straight line. Their gravity combines to cause very high and very low tides. These tides have the greatest difference between high and low tides.

Neap Tides

• Neap tides occur during the first and third quarters of the moon. The moon and sun are at right angles to each other. Their gravity pulls on the oceans in different directions. These tides have the least difference between high and low tides

• Pass out assignment 9

• Work on this assignment for the rest of the class period.

• We will finish it tomorrow in class if necessary.
