OCE ch 6 Questions with Correct Answers (Grade A+)
Question 1: The image below shows that about 30 percent of the Sun's energy is reflected and scattered
back into space. How would a 50 percent increase in Earth's albedo impact average surface
temperatures?
Answer: -Higher albedo would result in cooler temperatures on Earth. -Ice sheets would advance, thereby
increasing Earth's overall albedo and further cooling Earth's surface.
Question 2: Of the following statements about the tilt of Earth's axis, which one is true? Select only one
answer.
Answer: An increase in Earth's tilt would cause colder winters and warmer summers.
Question 3: Of the following statements about the transfer of heat on Earth, which is/are true? Choose
all that apply.
Answer: -Ocean currents move warm water from the tropics to higher latitudes. -Water vapor in the air
carries latent heat with it, which is released in other areas. -Air currents move warmer air from the tropics to
higher latitudes.
Question 4: The Coriolis effect is caused by __________.
Answer: the rotation of earth
Question 5: Where are Hadley cells found?
Answer: in the atmosphere near the equator
Question 6: What drives Hadley cell circulation?
Answer: heating from the Sun
Question 7: How does the location of the Intertropical Convergence Zone (ITCZ) change over time?
Answer: The ITCZ migrates south of the equator in Northern Hemisphere winter and north of the equator in
Northern Hemisphere summer.
Question 8: When would you expect the low-pressure cell over the North Pole to be most developed?
Answer: during the Northern Hemisphere winter
Question 9: Which areas of Earth experience the most precipitation?
Answer: areas near the ITCZ

, Question 10: What two features are many of Earth's deserts associated with?
Answer: the subtropical highs and cool ocean currents found along the west coasts of continents
Question 11: The Trade Winds are one type of prevailing wind pattern. How many other types of
prevailing winds are there among earth's global wind patterns?
Answer: 2
Question 12: Why does air tend to rise in equatorial regions?
Answer: Equatorial regions receive more direct sunlight than other areas.
Question 13: What is the air that sinks at latitudes of 30 degrees north and south like?
Answer: cool and dry
Question 14: What term is used to describe the effect on air movement produced by Earth's rotation?
Answer: the Coriolis effect
Question 15: Why does wind between the equator and 30 degrees south come out of the southeast?
Answer: Cooled air moves north toward the equator and is deflected toward the west by the Coriolis effect.
Question 16: In which direction would winds move at the poles if Earth rotated in the opposite
direction?
Answer: Wind near the north pole would move to the northeast, and the wind near the south pole would
move to the southeast.
Question 17: Which way would wind travel in the region between 30 and 60 degrees latitude if Earth
stopped rotating?
Answer: south in the Southern Hemisphere and north in the Northern Hemisphere
Question 18: The atmospheric high-pressure cells over North America in the map suggest that the
atmospheric patterns shown most likely represent which season for the northern hemisphere?
Answer: winter
Question 19: Variable winds that result in generally clear, dry, and fair conditions with minimal
precipitation are labeled number:
Answer: 6
