Here are the correct responses to each question:
-
How do prevailing winds produce ocean currents?
- Heat from the sun causes circulation patterns of warm and cool air.
-
Why do warm ocean currents begin at the equator?
- The equator receives more direct and intense sunlight, warming the water.
-
How are ocean currents in the Northern Hemisphere different from currents in the Southern Hemisphere?
- Currents in the Northern Hemisphere tend to move in a clockwise pattern.
-
In an El Niño year, trade winds are too weak to send warm currents west. Instead, warm currents travel east into South America. What is the end result of this difference in an El Niño year?
- Areas see significant changes in temperature and levels of precipitation.
