How do clouds form?
Liquid water is heated and evaporates and becomes water vapor in the atmosphere.
Water vapor in the atmosphere cools and condenses to become liquid water droplets floating in the atmosphere.
Tiny liquid water state droplets float upwards and gather together in the atmosphere to form a cloud.
Liquid state droplets warm then condense downward and once they his 50% humidity turn into visible clouds
As elevation _______________ temperature __________________.
increases, increases
increases, decreases
decreases, deceases
decreases, is not affect
Silver Iodide can be used for cloud seeding because:
It lows the air temperature allowing condensation to occur
It acts like water vapor and tricks the air into condensing
It has a similar structure to ice
It is not harmful, and inexpensive making it practical
Select the two types of Contrails: (Select two)
Exhaust
Fume
Aerodynamic
Aviation
Evaporation

True
False
Dew point is a good measure of how humid it feels.
True
False

Windiness
Brightness
What is a Front?
A boundary between two air masses of different density, moisture, or temperature.
A line that connects points of equal temperature.
The study of weather.
A large body of air that has properties similar to the part of Earth’s surface over which it develops.
What is a Cold Front?
a model that shows the weather conditions at a specific location on Earth’s surface.
Occurs when colder air advances toward warmer air.
when air is cooled near its dewpoint near the ground.
What is a Warm Front?
masses of puffy, white clouds, often with flat bases. They sometimes tower to great heights and can be associated with fair weather or thunderstorms.
High thin, white, feathery clouds made of ice crystals.
occur when colder air advances toward warmer air.
occurs when lighter, warmer air advances over heavier, colder air.
An air mass is a...
occurs when lighter, warmer air advances over heavier, colder air.
High thin, white, feathery clouds made of ice crystals.
the study of weather.
a large body of air that has properties similar to the part of Earth’s surface over which it develops.
What is Isobar?
a line drawn to connect points of equal atmosphere.
occurs when a boundary between air masses stops advancing.
a model that shows the weather conditions at a specific location on Earth’s surface.
Isotherm is?
a line drawn to connect points of equal atmosphere
occur when colder air advances toward warmer air.
involves three air masses of different temperatures-cold air, cool air and warm air.
a line that connects points of equal temperature.
