The Coriolis Effect Goal: To explain how the Earth’s rotation effect winds and ocean currents. Tonight’s homework: Quia Quiz due by Sun. 12/8 at 11:59 pm Warm-up: Take out your homework (DR 3.1 and section review) In your journal: In your own words, explain the Coriolis Effect. What causes it, and what does it do to moving water in the oceans? (pg. 82 for help)

Brain Pop!!!!

The Gravitron

What have I done?! This is Ho-Ho-Horrible! Hey, what the heck?

The Coriolis Effect

The Coriolis Effect Goal: To explain how the Earth’s rotation effect winds and ocean currents. Tonight’s homework: STUDY!! Quia quiz (if absent) Warm-up: Which direction does the Earth spin? What is the difference between ocean, surface, and deep water currents?

Global Wind Belts Goal: To identify and label the wind belts, ocean currents, and gyres on a world map. Tonight’s homework: Finish winds/ currents worksheet. Warm-up: What 3 factors control surface currents? Describe how each of these work.

Ocean Surface Currents

Deep Water Currents Goal: Tonight’s homework: DR 3.2 “Currents and Climate” Make predictions and observations about surface and deep water currents. Explain how differences in temperature can cause deep water circulation. Warm-up: Please take out your completed winds/ currents worksheet. Then, at your table, take two minutes to discuss the following questions: Why are some currents colored blue and some are red? Which ocean current has the biggest effect on us? Who else is greatly affected by this current?

El Niño Warm-up: Read over p. 88 – 89 in your book. Goal: Explain how changes in ocean currents can affect weather patterns and climate around the world. Tonight’s homework: 1) Quiz tomorrow - review DR 3.1 & 3.2 2) DR 3.3 “Waves” due Fri. ADVANCED SCIENCE: Quiz window Thurs. 1/5 to Mon. 1/9. Summaries/presentations due Wed. 1/11. Warm-up: Read over p. 88 – 89 in your book. In your journal: Describe El Niño, its causes and its effects.

El Niño is Spanish for…

What is El Niño? December 1993 December 1997 (normal conditions) El Niño is a phenomenon that occurs every few years during which the East Pacific ocean increases in temperature along the equator. December 1993 (normal conditions) December 1997 (El Niño conditions)

Watch what happens to the temperature. El Niño of 1997 Watch what happens to the temperature. 1) How long did the phenomenon last? 2) What caused this to happen? (What stopped?)

Effects on the Climate and Atmosphere Normal conditions During El Niño Coastal upwelling near S. America shuts down and the water warms up. How does this affect fish populations? How does this affect the rest of the world?

El Niño: La Niña: Warmer than average temperatures along the equator Cooler than average temperatures along the equator

Oceans Video Discussion Questions What is the Great Ocean Conveyor Belt, and what does it depend on for its existence? What does the black rock layer show about the history of life in the oceans and on land? What happened to Jellyfish Lake in 1998, and what caused this? What causes ocean acidification, and what might it result in?
