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 |
