|
| Earth’s innermost layer – comprised of dense elements – radius 3,400km |
|
|
|
| thin outer layer of Earth – less than 1% Earth’s mass |
|
|
|
| glide across asthenosphere – continents located on them – site of most geologic activity |
|
|
|
| surrounds the Earth – mixture of gases (nitrogen, O2, CO2, etc.) |
|
|
|
| flow of heat from a warmer object to a colder one |
|
|
|
| atmospheric layer nearest Earth’s surface- almost all weather occurs here |
|
|
|
| process in which gases trap heat near Earth – without ths Earth would be too cold to live |
|
|
|
| continuous movement of water into the air, onto the land, and then back to water sources |
|
|
|
| concentration of dissolved salts in ocean |
|
|
|
| 3% of Earth’s water is this – most in form of glaciers and icecaps |
|
|
|
| narrow layer around Earth where life can exist |
|
|
|
| flow of energy in which BOTH matter and energy are EXCHANGED between a system and a surrounding environment |
|
|
|
| energy (such as from sun) enters the environment but DOES NOT make it out |
|
|
|
| solid part of Earth’s interior – all rock, soils, and sediment on Earth’s surface |
|
|
|
| layer beneath lithosphere -a plastic, solid layer of the mantle – slow moving rock flows here |
|
|
|
| layer above troposphere – ozone (O3) in this layer absorbs’s sun’s UV energy |
|
|
|
| layer beneath the crust- 64% of Earth’s mass |
|
|
|
| large water droplets that fall as rain, snow, sleet or hail |
|
|
|
| water vapor that forms water froplets on dust particles that form clouds and fall as rain |
|
|
|
| Earth’s outer layer that includes the crust and uppermost part of the mantle – divided into tectonic plates |
|
|
|
| removal or transport of surface material by water or wind |
|
|
|
| molecule made up of 3 oxygen atomes – found in stratoshpere – absorbs UV radiation |
|
|
|
| transfer of energy across space and in the atmosphere |
|
|
|
| transfer of heat by air currents |
|
|
|
| process by which liquid water is heated by the sun and then rises into the atmosphere as water vapor |
