Definition
Chapter 2 Weather Factors
Term
The wavelengths of violet light are
Definition
Longer than the wavelengths of ultraviolet radiation
Term
Fluids like air tend to move toward areas of
Definition
Low pressure
Term
Earth's major wind belts are the trade winds, the prevailing westerlies, and the
Definition
Polar easterlies
Term
The three main types of clouds are cumulus, stratus and
Definition
Cirrus
Term
Most of the world receives
Definition
More rain than snow
Term
Heat transfer between 2 substances that are in contact is called
Definition
Conduction
Term
The freezing point of pure water on the Celsius scale is
Definition
0 degrees
Term
Winds are caused by differences in
Definition
Air pressure
Term
Local winds differ from global winds because they
Definition
Are caused by unequal heating within a small area
Term
Earth's rotation makes winds seem to curve. This is called
Definition
Coriolis effect
Term
Global winds generally
Definition
Blow from specific directions over long distances
Term
Wind speed is measured by an
Definition
Anemometer
Term
Clouds form when water vapor in the air
Definition
Becomes liquid water or ice crystals
Term
Layered clouds that often cover much of the sky are called
Definition
Stratus clouds
Term
Large clouds that often produce thunderstorms are called
Definition
Cumulonimbus clouds
Term
Very high feathery clouds are called
Definition
Cirrus clouds
Term
Relative humidity can be measured with a
Definition
Psychrometer
Term
Any form of water that falls from clouds is
Definition
Precipitation
Term
The difference between sleet and hail is
Definition
The size of the ice pellets and where they are formed
Term
Cool air masses tend to
Definition
Be more dense and flow under warm air masses
Term
Most of the heating of the troposphere comes from
Definition
Convection
Term
Energy from the sun that reaches Earth is mostly visible light, infrared radiation, and
Definition
Ultraviolet radiation
Term
Increased cooling that can make the air feel cooler than the measurement on the thermometer is
Definition
Wind chill factor
Term
Clouds form when water vapor in air becomes liquid water in a process called
Definition
Condensation
Term
Clouds that form near the ground and look like fluffy heaps of cotton are
Definition
Cumulus
Term
Flat layered clouds that cover most of the sky are
Definition
Stratus
Term
An ice pellet larger than 5 millimeters in diameter that forms during a thunderstorm is called a
Definition
Hailstone
Term
Mist and drizzle are made of small
Definition
Water droplets
Term
Winds that blow between the equator and the poles are
Definition
Global winds
Term
The temperature at which water in air changes from a gas to a liquid is the
Definition
Dew point
Term
Land breeze
Definition
The land cools more quickly and the wind blows from the land to the water because at night the land cools more quickly than the water.
Term
Sea breeze
Definition
The water warms up more slowly and the wind blows from the water to the land because during the day the sun warms the land faster.
Term
Three ways heat is transferred
Definition
Radiation: The direct transfer of energy by electromagnetic waves, conduction: The direct transfer of heat between substances that are touching, convection: the transfer of heat by movement of fluid
Term
Difference between sleet and freezing rain
Definition
Sleet forms when raindrops fall thru a layer of air below 0 dgrees celcius and the raindrops freeze into solid particles of ice as they fall. Freezing rain forms when raindrops do not freeze in the air, but instead freeze when they touch a cold surface
