- a form of energy that can travel through space
- electromagnetic waves
- the direct transfer of energy by electromagnetic waves
- radiation
- 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
- scattering
- 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
- thermometer
- What are the three ways that heat is transferred?
- radiation, conduction, convection
- energy transferred from a hotter object to a cooler one
- heat
- the direct transfer of heat from one substance to another that is touching it
- conduction
- the transfer of heat by the movement of fluids
- convection
- 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?
- convection
- Walking on hot sand and touching a spoon that is stirring a hot liquid are all examples of what form of heat transferring?
- conduction
- feeling heat from a campfire and heat lamps are all examples of what form of heat transferring?
- radiation
- 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
***ALL WINDS ARE CAUSED BY A DIFFERENCE IN AIR PRESSURE***** - wind SPEED is measured with a/an...
- anemometer
- 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
- monsoons
- 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
- evaporation
- a measure of the amount of water vapor in the air
- humidity
- 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
- rain
- stratus
- layered
- alto
- middle
- cirrus
- 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
