6th grade Matter, Water Cycle, Atmosphere

Conduction Exchange of heat by direct contact
Convection Transfer of heat in liquids and gasses through rising and falling currents
Radiation Transfer of heat by electromagnetic waves
Hydrosphere all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds
Precipitation rain, snow, sleet, or hail that falls to the ground
Hail pellets of frozen rain that fall in showers from cumulonimbus clouds
Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure
Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves
Condensation the conversion (changing) of a vapor or gas to a liquid
Geosphere The Solid Part of Earth
cryosphere is the frozen water part of the Earth system examples are North and South Polar regions
Atmosphere the envelope of gases surrounding the earth or another planet
Biosphere the regions of the surface, atmosphere, and hydrosphere of the earth
Troposphere is the lowest layer of Earth's atmosphere, almost all weather occurs within this layer
Stratosphere is the second major atmospheric layer above the troposphere, extending in altitude from about 8 to 30 miles high. No weather occurs in it, and it is where the ozone layer is located
Mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout this layer. Layer where most meteors burn up.
Thermosphere directly above the mesosphere and below the exosphere, the hottest layer in the atmosphere, contains the ionosphere where the northern and southern lights or auroras can be seen and also contains the exosphere with its the outer part of the atmosphere.
