Term
What is precipitation?
Definition
Is any form of water that falls from a cloud
Term
What are three states of matter?
Definition
Solid, liquid, and gas
Term
What is latent heat?
Definition
Is the energy absorbed or released during a change in state
Term
What is evaporation?
Definition
Is the process of converting a liquid to a gas
Term
What is condensation?
Definition
Is the change of state from a gas to a liquid
Term
What is deposition?
Definition
Is the process by which an agent of erosion loses energy and drops the sediment it is carrying
Term
What is relative humidity?
Definition
Is the ratio of the air's water-vapor content to it's water-vapor capacity
Term
What happens to heat when an object goes through a change in state?
Definition
When the water-vapor content of air remains constant, lowering air temperature causes an increase in relative humidity, and raising air temperature causes a decrease in relative humidity
Term
What instrument is used in measuring relative humidity?
Definition
Hygrometer
Term
What is the difference in dry and wet adiabatic rate?
Definition
The difference is that dry adiabatic rate only applies to unsaturated air and wet adiabatic rate are caused by latent heat
Term
What are the four mechanisms used to cause air to rise?
Definition
Lifting, frontal wedging, convergence, and localized convective lifting
Term
What is front?
Definition
Is the boundary between two adjoining air masses having contrasting characteristics
Term
What is temperature inversion?
Definition
A layer of limited depth in the atmosphere of limited depth where the temperature increases rather than decreases with height
Term
What type of weather can result when air rises?
Definition
Thunderstorms, and tornado
Term
What are the three types of clouds?
Definition
Cirrus, cumulus, and stratus
Term
Middle clouds have a prefix of.....
Definition
Alto
Term
What types of clouds tend to be high clouds?
Definition
Cirrus, cirrostratus, and cirrocumulus
Term
What types of clouds tend to be low clouds?
Definition
Strarus, Stratocumulus, and nimbostratus
Term
How is fog formed?
Definition
On cool, clear, clam nights when Earth's surface cools rapidly by radiation
Term
What is the Bergeron process?
Definition
A theory that relates the formation of precipitation to supercooled clouds, freezing nuclei, and the different saturation levels of ice and liquid
Term
What does supersaturated mean?
Definition
The condition of air that is more highly concentrated than is normally possible under given temperature and pressure conditions
Term
What are the forms of precipitation?
Definition
Rain, snow, sleet, glaze, and hail
Term
What type of clouds are the chief precipitation makers?
Definition
Nimbostratus clouds are one of the main precipitation markers
Term
What does the Latin word stratus mean?
Definition
It means to cover
