Answer
They let light and heat in and keep it in, raising
the temperature inside.
____________ is when the surface is heated by electromagnetic Radiation
waves in sunlight. Surface benefits more than atmosphere.
_____________ is when currents circulate warm air up and cool Convection
air down. It is a major cause of weather.
_____________ is when objects come in direct contact and
Conduction
heat is passed from one to the other. Objects resting on the
earth’s surface are affected by this.
A(n) _________________ front happens when a fast moving
Occluded
cold front overtakes a slower warm front.

What do isolines that are close together mean?
It means the slope is steep, the wind is strong,
the pressure changes rapidly
What measures relative humidity?
Psychrometer
What does a barometer measure?
