12. What effect can a very large volcanic eruption have on earth’s climate? (Points : 3)
It will warm the earth’s surface as more lava is released by the volcanic eruption.
It will cool the earth’s surface as radiation from the sun is blocked from entering the atmosphere.
It will cool the earth’s surface as more snow will fall with the presence of more condensation nuclei.
It will warm the earth’s surface as more heat is trapped by the dust particles.

13. What is the upward movement of cold water from the ocean depths called? (Points : 3)
La Niña
global warming
upwelling
El Niño

14. El Niño begins with which of the following? (Points : 3)
upwelling of cold ocean water

the westward movement of winds and currents in the Pacific

heavy mudslides in California and tornadoes in Florida

the eastward movement of winds and currents in the Pacific


15. What impact does El Niño have on the fishing industry? (Points : 3)
Ocean temperatures are too warm for some fish.
An increase in the number of sea birds depletes the fish supply.
Fishermen are unable to fish with the intense winds and currents.
Nutrients no longer come to the surface, so fish die or migrate.

16. Countries such as Australia and Indonesia will experience heavier than normal rains during which of the following? (Points : 3)
