Tiny solid and liquid particles suspended in the atmosphere

A mixture of many discrete gases, of which nitrogen and oxygen are most abundant, in which varying quantities of tiny solid and liquid particles are suspended

• The gaseous portion of a planet, the planet’s envelope of air; one of the
• traditional subdivisions of Earth’s physical environment.

• A description f aggregate weather conditions; the sum of all statistical
• weather information that helps describe a place or region

The totality of life forms on Earth

The rate of temperature decrease with height in the troposphere

• thin outer portion of earth: made up of crust and upper mantle, solid
• rock, part of the earth

“middle atmosphere” – between thermosphere and stratosphere

A molecule of oxygen containing three oxygen atoms

• The production of sugars and starches by plants using air, water,
• sunlight, and chlorophyll. In the process, atmospheric carbon dioxide is
• changed to organic matter and oxygen is released

A pollutant emitted directly from an identifiable sources

• A lightweight package of weather instruments fitted with a radio
• transmitter and carried aloft by a balloon

• A pollutant that is produced in the atmosphere by chemical reactions
• occurring among primary pollutants

The boundary between the stratosphere and the mesosphere

• The zone of the atmosphere above the troposphere characterize at first by
• isothermal conditions and then a gradual temperature increase. Earth’s ozone is
• concentrated here

• A layer in the atmosphere of limited depth where the temperature
• increases rather than decreases with height

• The zone of he atmosphere beyond the mesosphere in which there is a
• rapid rise in temperature with height

• The lowermost layer of the atmosphere marked by considerable turbulence
• and, in general, a decrease in temperature with increasing height.

The boundary between the troposphere and the stratosphere

The state of the atmosphere at any given time
