The Atmosphere
The most abundant gas in the atmosphere
What is Nitrogen?
This measure of humidity tells the actual amount of water vapor present in a certain volume of air.
What is absolute humidity?
This happens to snowflakes as they fall through a layer of air above 0 degree celsius.
What is they melt completely into raindrops
This process occurs when liquid water changes into water vapor.
What is evaporation?
The atmospheric layer that contains the ozone layer
What is the stratosphere?
This measure of humidity describes the percentage of water vapor in the air compared to the maximum amount the air can hold at that temperature.
What is relative humidity?
Name two of the factors necessary for precipitation
What are moisture, lifting, collision/coalescence, gravity, air temp
This phase change occurs when a gas turns into a liquid.
What is condensation?
What is the troposphere?
The name of the instrument that measures humidity using a wet and dry bulb thermometer.
What is a psychrometer?
The type of precipitation that occurs when the entire troposphere is below the melting point of ice and clouds are cold enough for ice crystals to grow?
What is snow?
In convection currents, this happens to warm air or liquid because it becomes less dense.
What is it rises?
The main reason the thermosphere feels cold despite high temperatures.
What is the air is too thin to transfer heat effectively?
As air cools to the dew point, water vapor condenses onto these tiny particles in the atmosphere, helping cloud droplets form.
What are condensation nuclei?
This is the main difference between sleet and freezing rain
What is sleet is already frozen when it hits the ground while freezing rain freezes on contact
This phase change occurs when a solid turns directly into a gas without becoming a liquid.
What is sublimation?
As altitude increases in the troposphere, this atmospheric property decreases, which is why it is harder to breathe on top of a mountain.
What is air pressure?
Name all 4 cloud forms
BONUS 2x if you describe their shapes correctly
What are
Cumulo form
Strato form
Cirro form
Nimbo form
This type of precipitation forms when raindrops are carried upward by strong winds in a thunderstorm, freezing into layers of ice.
What is hail?
This type of heat transfer is responsible for heating Earth from the Sun and can travel through empty space.
BONUS 2x: what happens to water under solar radiation?
What is radiation?
BONUS: Evaporation
