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.

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
3

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.
4

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.
5

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
6

Which event is associated with tornados?

A
sea levels rising due to high waves
B
coastal flooding due to storm surge
C
paths of damage up to 50 miles long
D
wind and rain lasting for several days
7

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.
8

Which is one way that analyzing ice benefits scientists who study ancient climates?

A
Scientists can analyze frozen volcanic dust to help predict eruptions.
B
Scientists can study the layers of ice cores to gather information about past atmospheric composition.
C
Scientists can use sand grains in ice to make inferences about the climate area.
D
Scientists can study tree rings in ice to learn more about past climates.
9

What must occur for air masses to form fronts?

A
They must increase in strength.
B
They must collide with each other.
C
They must move from west to east.
D
They must create air-pressure differences.
10

Which process contributes to the formation of tornados?

A
Water droplets freeze, giving off energy.
B
The storm begins to rotate around a central eye.
C
The Coriolis effect creates the spin of the storm.
D
Warm air rises, resulting in a decrease in air pressure.
11

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
12

How does altitude affect climate patterns in a region?

A
Areas at high elevations have cooler temperatures.
B
Air continues to warm as it rises to a higher elevation.
C
Tropical regions do not have many differences in altitude.
D
High-altitude areas have less variation in seasonal temperatures.
13

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
14

Which major type of air mass forms over warm water?

A
maritime polar
B
continental polar
C
maritime tropical
D
continental tropical

A
Move away from windows.
B
Seek shelter in a ditch or low-lying area.
C
Go to the lowest level of the building.
D
Lie on the floor and cover your head.
