10. ______ is caused by uneven heating of the Earth’s surface by the Sun ( Solar Energy).
11. _______ is also caused by difference in atmospheric pressure (same answer as #10).
12. A ____ breeze occurs when the Sun warms the land more than the water near the ocean.
13. A ______ breeze occurs at night when the water is warmer than the land.
13. ________ air/water is less dense than ______ air/water.
14. Ocean __________ are caused by convection – temperatures differences in the water.
15. Cold water currents move __________ from the poles, are more ________ than warm
water, and move slower than warm currents.
16. Cold water currents __________ and warm water currents rise.
17. Warm water currents move __________ from the equator, are less ________ than cold
water, and move faster than cold currents.
18. _______________ currents are wind driven (global winds).
19. _______________ currents are density and temperature driven.
Match the type of Severe Weather described below for #20 and #21:
20. ____________ moves across ocean to land with high winds that can last for days.
21. ____________ a violent rotating column of air with circulation that touches land and usually
last only minutes.
22. Which statement is true about density currents?
a. They circulate cold ocean water very slowly.
b. They are only formed in Antarctica.
c. They occur only in the Pacific Ocean.
23. Ocean Currents bring deep, nutrient-rich water to the surface. What causes these currents
to move upward?
