Clouds typically associated with thunderstorms.
Cumulonimbus
Summer Solstice (date)
June 21-22
Outermost layer of the Atmosphere; contains two minor layers.
Thermosphere
Conversion of a solid into a liquid state.
Melting
Also known as thermal energy.
Heat
Clouds that form sheets or layers.
Stratus
Winter Solstice (date)
December 21-22
Temperatures increase with height due to ozone. Located about the Troposphere.
Stratosphere
Conversion of a liquid into a solid state.
Freezing
The transfer of heat through matter by molecular activity.
Conduction
Cumulus
Sun's vertical rays are located at the equator. (0°)
Equinox
Autumnal or Spring (Vernal)
Zone of electrically charged gases. Coexists with the lower portion of the thermosphere.
Ionosphere
Conversion of a water vapor (gas) into a liquid state.
Condensation
A measure of the average kinetic energy of individual atoms or molecules in a substance.
Temperature
White to gray, "sheep-back" clouds.
Altocumulus
The parallel latitude located at 23.5° north of the equator.
Tropic of Cancer
Lowermost layer of the Atmosphere. Most weather occurs here.
Troposphere
Conversion of a liquid into a gas.
Evaporation
The transfer of heat by movement of a mass or substance. (Can only take place in fluids)
Convection
Amorphous layer of dark, gray clouds. Often produce precipitation.
Nimbostratus
The parallel latitude located at 23.5° south of the equator.
Tropic of Capricorn
Coldest layer of the Atmosphere.
Mesophere
Conversion of a solid directly to a gas without passing through the liquid state.
Sublimation
The transfer of energy (heat) through space by electromagnetic waves.
