a form of energy that can travel through space
electromagnetic waves
the direct transfer of energy by electromagnetic waves
a form of energy with wavelengths that are longer than red light
infrared radiation
a form of energy with wavelengths that are shorter than violet light
ultraviolet radiation
reflection of light in all directions
the process by which gasses hold heat in the air
greenhouse effect
What is air temperature usually measured with?
a thermometer
a thin glass tube with a bulb on one end that contains a liquid that is usually mercury or colored alchahol
What are the three ways that heat is transferred?
radiation, conduction, convection
energy transferred from a hotter object to a cooler one
the direct transfer of heat from one substance to another that is touching it
the transfer of heat by the movement of fluids
What conducts heat the best: Solids, liquids, or gasses
Solids. Next is liquid, then gas
Drying boots through a hot air vent, and a furnace heating a whole house are examples of what form of heat transferring?
Walking on hot sand and touching a spoon that is stirring a hot liquid are all examples of what form of heat transferring?
feeling heat from a campfire and heat lamps are all examples of what form of heat transferring?
Energy fro the sun is....
reflected from the surface to back into the atmosphere

absorbed by the land- some of the absorbed energy is radiated back into the atmosphere

gas and particles in atmosphere absorb energy, and also reflect and then scatter light
Put these in order from shortest wavelengths to longest wavelengths.

visible light, infrared radiation, ultraviolet radiation
infrared, visible, UV
Winds move from...
areas of high pressure to low pressure
the horizontal movement of air from an area high pressure to low pressure

wind SPEED is measured with a/an...
increased cooling that wind can cause
wind-chill factor
winds that blow over short distances, caused by unequal heating of the earth's surface within a SMALL AREA
local winds
A wind that blows FROM and ocean TO the land is called a...
sea breeze
a wind that blows FROM the land TO a body of water
land breeze
sea breezes and land breezes over a large reigon that change direction with the seasons
the way the earth's rotation makes the wind move
coriolis effect
bands of high speed winds
jet streams
HOW does unequal heating of the earth's surface cause winds?
the hotter air rises and cooler air is forced underneath it, which causes a breeze.
the process by which water molecules in liquid water escape into the air as water vapor
a measure of the amount of water vapor in the air
the percentage of water vapor in the air compared to the maximum amount the air could hold
relative humidity
what is an instrument that measures relative humidity
a psychrometer
how do clouds form?
water condenses
the temperature at which condnsation begins
dew point
Latin root: cumulus
big, puffy
Latin root: nimbus
wispy, light feathery
How do you measure rain fall?
a rain gauge
energy of motion in the molecules of a substance
thermal energy
The movement of air between the equator and the poles produces....
global winds
common types of percipitation
rain, sleet, freezing rain, hail, snow
Why is the sky blue?
blue light is scattered more than other wavelengths so it appears blue
why is the sky red
the horizon is very long. When the un sets, it has longer wavelengths to cover the long distance, so it apperars redish orange
HOw does a thermometer work?
the liquid inside the bulb expands when heated and deflates when cooled
Which type of heat transfer is in action when a fireplace is lit?
ALL of them:

Radiation: The heat to the room

Convection: heat travels up through chimney

Conduction: when you light the fire, and then wood burns
WHen is the only time that land breezes happen during the day globally?
summer monsoons
