|---|
| condensation | the process in which water vapor turns into liquid water |
| evaporation | the process by which liquid water changes to water vapor |
| the energy source that keeps the water cyce going | the sun |
| an aerosol | in order to form clouds you need cold air, water vaopr an this |
| precipitation | any form of water falling to the ground |
| water vapor | the gas from of water; it is invisible |
| the manipulated or independant variable | you change this variable in an experiment with short wavelengths |
| responding or dependant variable | this variable changes because of changes made to the manipulated/independant variable |
| convection | this type of heat transfer is most responsible for heating the troposphere |
| greater | cold air has __________ density than warm air |
| less | warm air has __________ density than cold air |
| degrees | units used to measure temperature |
| move faster and expand | molecules of a warm substance |
| move slower and contract | molecules of a cold substance |
| conduction | Touching a hot pan is an example of this type of heat transfer |
| convection | the movement of heat by a fluid such as air or water |
| 212 degrees | boilong point of water in Fahrenheit |
| radiation | the sun's energy reaches us by this type of heat transfer |
| convection currents | created when warm air rises and cold air sinks |
| more dense | cold air sinks for this reason |
| 100 degrees | boiling point of water in Celsius |
| true | convection is the type of heat transfer MOST responsible for heating our atomosphere |
| thermometer | tool used to measure temperature |
| false | true or false: rubber is a good conductor of heat |
| less dense | the solar bag rose because the air inside became __________________ when it was heated |
| control | in this part of an experiment, there is no change made to the manipulated variable. It is a way to see if the experiemnt is well designed |
| constants | parts of an experiemnt that are kept the same in all trials and for all levels |
| manipulated variable | the part of the experiment YOU change |
| responding variable | this variable changes in response to changes made to the manipulated variable |
