The forecast calls for thunderstorms. Which is MOST LIKELY to be the cause of this weather?

A cold air mass is colliding with a moist, warm air mass.

What does the jet stream influence?

It causes weather patterns to move from west to east.

What are you actually seeing when you see the mirror cloud up?

Water droplets formed from cooled water vapor in your breath

What type of weather condition sometimes results in a fog?

Moist air passes over cooler ground

Which of the following explains what happens to the density of the air over land as it warms?

The density decreases as the air warms up and expands.

Which of the following is the MOST REALISTIC interpretation of the map?

A cold front is heading toward Michigan.

Why are cloudy skies less common over deserts?

Lack of water vapor in the air limits cloud formation.

What characteristic of oceans tend to influence regional Earth’s climate?

Oceans have a higher heat capacity than land.

A group of scientists recorded an increase in the average temp of the North Pole this year.

The weather was different this year than in the past.

On a hot day, a glass of ice water collects liquid on the outside of the glass. Why?

Water vapor outside of the glass collected on the glass.

Which of the following is true regarding the properties of an air mass?

An air mass has similar temperature and moisture throughout.

A cold air mass remains stationary for a period of time.
A cold air mass is colliding with a moist, warm air mass.
A warm air mass remains stationary for a period of time.
6
When a climber gets to the top of a mountain she finds it harder to breathe. Why is this true?
The air pressure is greater.
The greenhouse effect has increased.
The atmosphere is less dense.
The top of the mountain is closer to the sun.
7
What does the jet stream influence?
It causes precipitation to runoff into watersheds.
It causes habitat destruction in oceans.
It causes the atmosphere’s gas mixture to change.
It causes weather patterns to move from west to east.
8
What are you actually seeing when you see the mirror cloud up?
Cooled nitrogen in the air around you
Carbon dioxide that you are breathing out from your lungs
Water droplets formed from cooled water vapor in your breath
Oxygen that you are breathing out from your lungs
9
What type of weather condition sometimes results in a fog?
Air pressure increases and water vapor decreases
Humidity decreases and air temperature increases
Moist air passes over cooler ground
Cool rain falls on warmer ground
10
What type of weather can be expected when a warm front approaches?
Warm days and cool clear nights in fall
Sudden hurricanes in spring
Rain and thunderstorms in summer
Steady snowfall in winter
11
The amount of water vapor in the air depends mostly on the which of the following?
The shape of the clouds in the sky.
The speed of the wind.
The temperature of the air.
The amount of oxygen in the air.
12
Which of the following explains what happens to the density of the air over land as it warms?
Density doesn't change b/c the land temp is not affected
The density does not change because it is replaced.
The density decreases as the air warms up and expands.
The density increases as the air warms up and contracts.

City 4
City 1
City 3
City 2
18
Why are cloudy skies less common over deserts?
Air masses in the desert move slowly.
Lack of water vapor in the air limits cloud formation.
Water evaporates faster in the desert.
Strong jet stream winds keep clouds away.

Hydrogen and nitrogen
Oxygen and nitrogen
Oxygen and carbon dioxide
Hydrogen and oxygen
22
A group of scientists recorded an increase in the average temp of the North Pole this year.
The weather was different this year than in the past.
Global warming is taking place.
The climate around the North Pole has changed.
The average temp next year will be even higher next year.
23
On a hot day, a glass of ice water collects liquid on the outside of the glass. Why?
Water and air from inside collected on the outside.
Air molecules outside of the glass turned into liquid.
Water from the inside the glass seeped outside of the glass.
Water vapor outside of the glass collected on the glass.
24
