Science Chapter 2 te

Section 1-3

electromagnectic waves Waves that transfer electric and magnetic energy through the vacuum of space.
radiation The direct transfer ofenergy by electromagnetic waves.
infrared radiation Electromagnetic waves with wavelength that are longer than visible light but shorter than microwaves.
ultraviolet radiation Electromagnetic waves with wavelengths that are shorter than visible light but longer than x-rays.
scattering Reflection of light in all directions.
greenhouse effect Gases in the atmosphere that trap energy.
temperature A measure of how hot or cold an object is compared to a refrench point.
thermal energy The total energy of motion in the particles of a substance
thermometer An instrument used to measure tempature
heat The transfer of thermal energy from one object to another because of a diffrence in tempature.
conduction The direct transfer of thermal energy from one subtance to another by direct contact.
convection The transfer of thermal energy by the movement of a fluid
convection currents The circulation of a fluid as it alternately heats up and cools down.
wind the horizontal movement of air from an area of high pressure to an area of lower pressure.
anemometer An instrument used to measure wind speed.
wind-chill factor A measure of cooling combining tempature and wind speed.
local winds Winds that blow over short distances
sea breeze The flow of cooler air from over an ocean or lake toward land.
land breeze The flow of air from land to a body of water.
global winds Winds that blow steadily from specific directions over long distances.
Coriolis effect The change that Earth's rotation causes in the motions of objects and that explains how winds curve.
jet stream Bands of high-speed winds about 10 kilometers above Earth's surface.
