Name that Line
Rays from the Sun hit this line of latitude most directly (90 degree angle) during the June Solstice. It is located at 23.5 N. The Sun would be directly overhead of a person at this time and place.
Tropic of Cancer
What is the name of the star which the North Pole is directed toward?
Polaris
During Normal Conditions, Tradewinds in the equatorial Pacific move in what direction?
East to West
What happens to Tradewinds in the equatorial Pacific during El Niño?
Winds Weaken
This is the tilt of the axis of Earth as it orbits the Sun
23.5 degrees
Rays from the Sun hit this line of latitude most directly (90 degree angle) during the Winter Solstice. It is located at 23.5 S. The Sun would be directly overhead of a person at this time and place.
Tropic of Capricorn
Refer to figure 1 on the board. Which shows the position of the Earth when the Southern Hemisphere is experiencing Summer
position 2
During normal conditions, as warm water is pushed toward Australia and Asia, cold water rises from the depth along South America, brining nutrients up, which is good for fish. What is this process called?
Upwelling
What happens to upwelling near South America during El Niño?
Pushed back down
DOUBLE JEOPARDY!!! Describe what happens as the angle of incidence from the Suns rays decrease? In other words, the rays from the Sun hit the Earth at a less direct angle.
Less intensity, smaller surface area, cooler conditions on Earth
The region of Earth between the South Pole and 66.5 degrees S. This region may receive an entire 24-hour period of daylight at certain times of the year.
Antarctic Circle
If the angle of incidence is 90 degrees (rays from the Sun are directly oriented) at the tropic of cancer, what season is the Southern Hemisphere experiencing?
Start of Winter
Under normal conditions, where do Tradewinds push warm water in the equatorial pacific? Toward South America or Australia/Asia?
Australia / Asia
What happens to fish populations during El Niño?
Migrate / negative effect
When rays from the Sun are shining directly on the Equator (90 degree angle). The Sun would be at the zenith (directly overhead) of someone at noon standing at the equator at this time.
Equinox (Fall - Sept 21 / Spring - March 21)
The region of Earth located between the North Pole and 66.5 degrees N. This region may receive an entire 24-hour period of daylight at certain times of the year.
Arctic Circle
Refer to Figure 1 on the Board. Which position shows the Northern Hemisphere experiencing Summer.
Position 1
DOUBLE JEOPARDY!!! What happens to Tradewinds during La Niña?
Strengthen
How does El Niño affect hurricanes in the North Atlantic?
Less intense hurricane season
What effect does La Niña have on hurricanes in the North Atlantic?
During both the fall and spring equinox, the Sun sun shines most directly (90 degree angle) on this line of latitude.
Equator
Refers to a point in the sky located directly overhead
Zenith
What conditions might South America experience during El Niño?
Heavy Rain / flooding
How often does El Niño occur?
Every 2-7 years.
The axis of Earth rotates in a process called? The North Star changes over a long period of time due to this process.
Precession
