What is the definition of atmosphere?
the gaseous envelope surrounding the earth; the air
What is the definition of conduction?
the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts.
What is the definition of radiation?
the process in which energy is emitted as particles or waves
What is the definition of convection?
the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
What is the definition of the troposphere?
the lowest layer of the atmosphere, 6 miles (10 km) high in some areas and as much as 12 miles (20 km) high in others, within which there is a steady drop in temperature with increasing altitude and within which nearly all cloud formations occur and weather conditions manifest themselves
What is the definition of precipitation?
the act of precipitating; state of being precipitated.
What is the definition of the mesosphere?
(in the classification of the earth's atmosphere by thermal properties) the region between the stratosphere and the thermosphere, extending from about 20–50 miles (32–80 km) above the surface of the earth.
What is the definition of wind?
air in natural motion, as that moving horizontally at any velocity along the earth's surface
What is the definition of stratosphere?
the region of the upper atmosphere extending upward from the tropopause to about 30 miles (50 km) above the earth, characterized by little vertical change in temperature.
What is the definition of air mass?
a body of air covering a relatively wide area, exhibiting approximately uniform properties through any horizontal section.
What is the definition of thermosphere?
the region of the upper atmosphere in which temperature increases continuously with altitude, encompassing essentially all of the atmosphere above the mesosphere.
what is the definition of evaporation?
the state of being evaporated
What is the definition of exosphere?
the highest region of the atmosphere, where the air density is so low that a fast-moving air molecule is more than 50 percent likely to escape from the atmosphere instead of hitting other molecules.
what is the definition of a warm front?
a transition zone between a mass of warm air and the colder air it is replacing.
What is the definition of density?
the state or quality of being dense; compactness; closely set or crowded condition.
What is the definition of a front?
the foremost part or surface of anything
What is the definition of Altitude?
the height of anything above a given planetary reference plane, especially above sea level on earth.
what is the definition of a dew point?
the temperature to which air must be cooled, at a given pressure and water-vapor content, for it to reach saturation; the temperature at which dew begins to form.
What is the definition of air pressure?
the force exerted by air, whether compressed or unconfined, on any surface in contact with it.
what is the definition of particulate?
a material composed of such particles.
