- amosphere
- earths air which is made up of a thin layer of gases ,solids ,and liquids form a protective layer around the planet and is divided into five different layers
- troposphere
- layer of earths atmosphere that is closest the ground contains 99 percent of water vapor and 74percent of the atmospheric gases and id where clouds and weather occur
- ionosphere
- layer of electrically charged particles in the thermosphere that absorbs Am radio waves during the day and reflects them back at night
- ozone layer
- a layer of the stratosphere with high concentration of ozone absorbs most of the suns harmful ultraviolet rays
- ultraviolet radiation
- a type of energy that comes to earth from the sun can damage skin and cause cancer also is mostly absorbed by the ozone layer
- chlorofluorocarbons
- a group of chemical compound used in refrigerators, air conditioner, foam packaging, and aerosol sprays that may enter the atmosphere and destroy the ozone layer
- radiation
- energy that is transferred by waves
- conduction
- transfer of energy by collusions between the atoms in a material
- convection
- transfer of heat that occurs when particles move between objects or areas of different temperatures
- coriolis effect
- in the southern hemisphere and turn right in the northern hemisphere due to earths rotation
- jet stream
- a narrow belt of strong winds that blows near the top of the troposphere
- sea breeze
- movement of air from sea to land during the day
- land breeze
- movement of air from land to sea at night
- hydrosphere
- all water on earths surface
- water cycle
- rain, evaporation, condesed into clouds, becomes liquid, falls to earth as precipitation
