Combustion
the burning of materials
nitrogen cycle
the repeated movement of carbon through the environment in different forms
carbon cycle
the repeated movement of carbon through the environment in different forms
condensation
the changing of a gas to liquid
precipitation
water that falls from clouds as rain, snow, sleet or hail
evaporation
the changing of a liquid to a gas(water vapor)
front
a boundary between two large bodies of air with different terperatures, amounts of water vapor and pressure
Dopplar radar
a computer that detects precipitation and how wind affects its movement
meteorologist
a person who reports and forecasts weather conditions
climate
the average weather conditions over a long time
elevation
the height above sea level
latitude
a measure of how far a place is from the equator
barometer
an instrument that measures atmospheric (air) pressure used in forecasting weather
water vapor
water in the form of gas in the air
sublimation
the process of ice turning directly into water vapor without turning into water first
Plant
take in carbon dioxide and releases oxygen(in the oxygen cycle)
Animals
take in oxygen and release carbon dioxide(in the carbon cycle)
In what three states can water exist
Water can exist in the state of water(liquid), ice(solid) and water vapor(gas)
Four steps of the water cycle include the following
evaporation, condensation, precipitation and runoff
Four factors that affect the steps of the water cycle are
temperature, air pressure, wind and elevation of the land
What are some different paths that the water cycle can follow
Condensation can form clouds but it can also form dew

Sublimation causes the forming of frost on surfaces instead of the ice melting first and becoming liquid water
