Which is a possible consequence of decreasing air quality resulting from global warming?

A
drying out of fertile lands
B
flooding of low-lying coastal areas
C
melting of glaciers and polar ice caps
D
decrease in population due to health threats
3

How is warm front formation different from occluded front formation?

A
A warm air mass rises above a cold air mass during a warm front, but two cold air masses surround a warm air mass during an occluded front.
B
Two cold air masses surround a warm air mass during a warm front, but a cold air mass moves against a warm air mass during an occluded front.
C
A cold air mass moves faster than a warm air mass during a warm front formation, but a cold air mass is pushed upward during an occluded front.
D
A warm air mass and a cold air mass form a boundary during a warm front, but water condenses between two air masses during an occluded front.
4

Which describes one characteristic of both El Niño and La Niña?

A
Both are causes of long-term climate change.
B
Both create warmer water.
C
Both occur in the Pacific Ocean.
D
Both are causes of hurricane activity.
5

Which describes an effect that ocean currents have on short-term climate change?

A
Ocean currents increase the strength of prevailing winds, which can cool the air and land.
B
Ocean currents can carry cold water, which can cool the air and land.
C
Ocean currents increase hurricane activity, which can raise the temperature of the air and land.
D
Ocean currents carry cold water, which may not affect hurricane activity and lower the temperature of the air and land.
6

Which correctly lists the three weather factors that are indicators of climate change?

A
sunsets, wind patterns, clouds
B
ocean currents, ice cores, temperature
C
temperature, wind patterns, ice cores
D
wind patterns, temperature, ocean currents
7

Which is one function of a weather balloon?

A
enables forecasts seven to 10 days in advance
B
measures conditions in the upper atmosphere
C
locates and tracks storms and follows the path of storm systems
D
uses mathematical equations to show what will happen if conditions change
8

A
being struck by lightning
B
being hit by thunder
C
being caught by falling hail
D
being carried away by strong winds
9

Which is a negative effect of rising ocean temperatures?

A
the drying out of fertile land and the formation of dust bowls
B
the flooding of low-lying coastal areas
C
the faster evaporation of water in the soil
D
the decreased frequency of major storms
10

Which statement best describes monsoons?

A
They force cool, moist air from oceans to rise.
B
They are winds that blow in the opposite direction of a normal wind.
C
They bring heavy rain in the winter and in the summer.
D
They influence precipitation as wind moves near a mountain.
11

Which high-altitude wind system varies in speed based on its distance from the equator and plays a significant role in directing air masses across the globe?

A
polar winds
B
jet streams
C
currents at the equator
D
thermal currents
12

Which is one source that scientists use to reconstruct past climate conditions?

A
fossils frozen in glaciers
B
daily temperatures
C
the tilt of Earth’s axis
D
running water
