460. The El Niño–Southern Oscillation (ENSO) is a recurring climatic
pattern that starts with ocean surface cooling or warming of waters
in the central and eastern tropical Pacific Ocean. This change in
ocean surface temperatures causes drastic changes to the climate of
regions around the world. Which of the following events is caused
by El Niño?
(A) increased rainfall to parts of Pacific Coast of South America
(B) cooler temperatures over Western and Central Canada
(C) wetter conditions in the Pacific Northwest
(D) stronger winds worldwide
461. Each year, carbon dioxide levels in the atmosphere reach a peak level
around the same time in the winter. Globally, what is happening
annually that would account for such a predictable repeating pattern
of these increases in carbon dioxide?
(A) more coal-fired stoves in winter
(B) more cars on the road
(C) earth is closest to the sun
(D) winter in the Northern Hemisphere

462. Many environmentalists believe that eating less red meat will help to
combat climate change. CAFOs (concentrated agricultural feeding
operations) such as large-scale cattle farms contribute to climate
change because
(A) the cattle release large amounts of methane, which is a
greenhouse gas
(B) the cattle eat a lot of grass, which decreases the amount of CO2
absorbed by grass
(C) the cattle waste (urine and feces) ends up in runoff in the ocean
(D) more plants equal more photosynthesis and less CO2

463. Of the following alternative energy sources, which has the highest
energy return on energy invested?
(A) photovoltaic solar
(B) hydroelectric
(C) geothermal
(D) wind
464. Which is the greatest threat to global sea-level rising?
(A) melting of the Antarctic ice shelf
(B) thermal expansion of the water
(C) breakdown of the polar ice caps
(D) increased erosion and river runoff

465. Which of the following would be a result of ocean warming?
(A) increase in hypoxia zones (low oxygen levels)
(B) decrease evaporation over the oceans
(C) decrease frequency and severity of storms (hurricanes)
(D) increase the pH of ocean water
466. Hypoxic zones can occur naturally. These are areas in which
dissolved oxygen levels become dangerously low, and organisms start
to die off in large quantities. Some of the causes are excess nutrients
in the water and ocean warming. What is another name for these
areas?
(A) low oxygen zones
(B) oxygen minimum areas
(C) oxygen missing zones
(D) dead zones
467. Which scenario would “hold” the most dissolved oxygen?
(A) salty and cold water
(B) fresh and cold water
(C) fresh and warm water
(D) salty and warm water

shells they use for locomotion, protection, and their homes.
(A) carbon dioxide
(B) magnesium oxide
(C) calcium hydroxide
(D) calcium carbonate

Which compound is created when carbon dioxide and water are
combined?
(A) carbon trioxide
(B) carbonate ions

470. Which substance acts as a buffer to help regulate the pH of
seawater?
(A) carbon dioxide
(B) carbonate ions
