| Question | Answer |
|---|---|
| the condition of earth's atmosphere at a certain time and place | weather |
| a measure of the average kinetic energy of particles | temperature |
| the total kinetic energy of particles | thermal energy |
| the increase in volume that results from an increase in temperature | thermal expansion |
| the energy that is transferred between objects that are at different temperatures | heat |
| the transfer of energy as electromagnetic waves | radiation |
| the transfer of energy from one object to another through direct contact | conduction |
| the transfer of energy due to the movement of matter | convection |
| the mixture of gases that surrounds earth | atmosphere |
| the measure of the force with which particles in the air push on an area of a surface | air pressure |
| the lowest layer of the atmosphere and has an average thickness of 10 to 12km | troposphere |
| the layer of atmosphere above the troposphere | stratosphere |
| the area of the stratosphere that is located between 15km and 40km above earth's surface | ozone layer |
| the atmosphere layer above the stratosphere | mesosphere |
| the uppermost layer of the atmosphere | thermosphere |
| the process by which gases in the atmosphere such as water vapor and carbon dioxide absorb and give off infrared radiation | greenhouse effect |
| areas of different air pressure cause changed in the weather. this kind of air sinks slowly down | high pressure system |
| air rises and so has a lower air pressure than the areas around it | low pressure system |
| the movement of air caused by differences in air pressure | wind |
| the apparent curving of the path of a moving object from an otherwise straight path due to earth's rotation | coriolis effect |
| narrow belts of high speed winds that blow from west to east between 7km and 16km above earth's surface | jet stream |
| the movement of air over short distances | local wind |
| when the air from the sea moves up onto land | sea breeze |
| when the air from the land moves down into the sea | land breeze |
