Atmosphere: Energy transfer Flashcards
Transfer of energy by electromagnetic waves, or energy that can travel through space
Radiation
99% of radiant energy from the Sun that reaches Earth is?
Visible light Infrared radiation (IR) Ultraviolet light (UV)
Majority of sunlight in the form of a mixture of all the colors you can see in a rainbow
Visible light
Form of energy with wavelengths longer than visible light and is not visible but can be felt as heat
Infrared radiation (IR)
Has short wavelengths and can break chemical bonds
Ultraviolet light (UV)
As sunlight enters the atmosphere, it is convert to air, a natural process to regulate temperature on Earth, which is one if the most important elements of weather
Greenhouse effect
What are the three ways heat is transferred?
Radiation
Conduction
Convection
Transfer of thermal energy by contact of particles of matter; occurs where atmosphere touches Earth (direct transfer)
Conduction
Transfer of thermal energy by movement of particles within matter; heating of air currents (transferred by fluid)
Convection
True or False?: Hot air sinks
False
True or False?: Cold air sinks
True
Refers to whether circulating air motions will be strong or weak stable conditions are caused by weak circulating air unstable conditions are caused by strong moving air usually producing thunderstorms
Stability
Occurs in the troposphere when temperature increases as altitude increases trapped pollution can be a result of this
Temperature inversion
Things that are ad at transferring heat, they don’t stop heat, they slow it down
Insulators
Absorbed from the sun and absorbed in the earth and is thrown back at the sun
Terrestrial Radiant
