What causes dew to form on grass?
Temperature of nearly saturated air rises to just above the dew point
The grass sheds excess water
Mist
Temperature of nearly saturated air cools to just below the dew point
Which of these is NOT necessary for cloud formation?
Cooling air
Particle of salt/dust/ice in the air
Warming air
Air saturated with water
What is adiabatic cooling?
Air condenses as it rises
Temperature of air increases as it rises and expands
Air condenses as it falls
Temperature of air decreases as it rises and expands
In adiabatic cooling, why does air rise?
The air is cold
The air is moving
Heat from the ground warms the air
Heat from the sun warms the air
In adiabatic cooling, what happens when rising air cools to the dew point?
It expands
Clouds form
It keeps rising
It begins to sink
What is the process by which the temperature of an air mass decreases as the air mass moves over a cold surface?
Advective cooling
Adiabatic cooling
Precipitation
Condensation
What might happen when moving air is forced upwards by a mountain range?
The air warms, forming clouds
The air cools, forming clouds
Nothing happens
The air condenses, breaking apart clouds
Which type of clouds are flat and found at low altitudes?

Cirrus
Cumulus
What type of cloud is billowy and looks like a cotton ball?
Stratus
Cumulus
Cirrus
Which is NOT true of cumulonimbus clouds?
They are very tall.
They are wispy and thin.
They result in rain, lightning, and thunder.
They often appear dark.
What is a wispy cloud at high altitudes composed of ice crystals?
Stratus
Cumulus
Cirrus
Which is ALWAYS true of fog?
It is thicker than clouds.
It is thinner than clouds.
It forms near the Earth's surface.
It forms overnight.
Which of the following statements about precipitation is NOT true?
Much of the rain that falls to the ground starts as snow high in the clouds.
Sleet forms when rain falls through a layer of freezing air close to the ground.
Hail forms through a process of convection in cumulonimbus clouds.
Rain that falls to the ground always starts as rain in the clouds.
