(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

A layer of concentrated ozone (O ) in the stratosphere that shields the earth from harmful ultraviolet light.
ozone layer
Natural atmospheric gases such as water vapor, carbon dioxide, and methane that warm the atmosphere by the greenhouse effect.
greenhouse gas
The atmosphere refers to the layer of gases that surrounds the Earth (or other astronomical body).
atmosphere
lowest layer of Earth's atmosphere, extending from the Earth's surface up to an average altitude of about 11 kilometers
troposphere
Free!
he layer of Earth's atmosphere located above the troposphere. It extends roughly from an altitude of about 11 kilometers to 50 kilometers above the Earth's surface.
stratosphere
The emission of electromagnetic waves. such as with sunlight or heat lamps.
radiation
The flow rate of radiant energy from the sun through space to reach Earth.
solar constant
The movement of thermal energy through a medium. The transfer of thermal energy by direct contact between two substances.
conduction
The steady drop of temperature within altitude in the troposphere.
lapse rate
A belt of high-speed winds in the stratosphere that flow across the upper and middle latitudes.
jet stream
A process by which a planet’s atmosphere keeps energy from being lost to space. The greenhouse effect protects life on Earth by retaining sufficient energy to maintain liquid water.
greenhouse effect
A region of variable height in the earth’s atmosphere where solar radiation breaks gas molecules into ions.
ionosphere
A region of the earth’s atmosphere in which there is a uniform mixture of gases.
homosphere
fourth layer of Earth's atmosphere. It begins approximately at an altitude of about 80 km to about 500 km.
thermosphere
A region of the earth’s atmosphere in which there are distinct layers of different gases.
heterosphere
outermost layer of Earth's atmosphere, located above the thermosphere. It is the uppermost layer of the atmosphere and gradually transitions into the vacuum of space.
exosphere
The geomagnetic field that surrounds the earth originating in the earth’s interior and extending to 160,000 km.
magnetosphere
The transfer of thermal energy by the flow of a fluid caused by differences in density.
convection
third layer of Earth's atmosphere. It extends approximately from an altitude of about 50 kilometers to 80 kilometers above the Earth's surface. Contains the coldest temperatures in the atmosphere.
mesosphere
