Definitions
100

This is the weather layer of the homosphere.

What is the troposphere?

100

This "sphere" lies at the upper portions of the Mesosphere & lower portions of the Thermosphere. Gases are ionized here.

What is the ionosphere?

100

A low concentration of ozone centered over Antarctica that shows up a few months a year.

What is the ozone hole or hole in the ozone?

100

Places where the composition of air is the same at any level.

What is the homosphere?

100

What is the definition of atmosphere?

The mass of air surrounding a planet.

200

In this layer, meteors enter out atmosphere and re burned up.

What is the mesosphere?

200

Glowing regions of brilliant colors that move across the night sky caused by high energy collisions between ionized particles in the ionsphere.

What are auroras?

200

A man-made substance connected to the ozone hole.

What is CFCs or the Chlorofluorocarbons?

200

Place where the composition of air changes at different levels.

What is the heterosphere?

200

What is the definition of atmospheric pressure?

The pressure exerted by the atmosphere on all objects within it.

300

In this layer, there are no weather phenomena, but jet streams are found in its lower portion.

What is the stratosphere?

300

Many space shuttle missions happen here and this level was named for its high energy bu low temperature.

What is the thermosphere?

300

A weather phenomenon around the South Pole responsible for sending chlorine into the ozone.

What is polar vortex?

300

Instrument used to measure atmospheric pressure

What is the barometer?

300

What is the definition of jet stream?

Narrow bands of high-speed winds that circle the earth, blowing from west to east.

400

In these 2 layers, temperatures decrease as altitude increase.

What are troposphere & mesosphere?

400

This level is the last level before interplanetary space.

What is the exosphere?

400

World leaders signed this treaty that banned CFCs in an effort to stop depletion of the ozone.

What is the Montreal Protocol?

400

The pressure exerted by the atmosphere on all objects.

What is atmospheric pressure?

400

What is the definition of heat?

Energy that is transferred as a consequence of temperature differences.

500

In this level, temperatures increase as altitude increases.

What is stratosphere?

500

These 2 layers of the atmosphere can be considered "outer space."

What are the thermosphere and exosphere?

500

The ozone layer is significantly lower over the Antarctica during these months.

What is August-November?

500

The average amount of atmospheric pressure at sea level exerts this many pounds per square inch.

What is 14.7 pounds?

500

What is the definition of temperature?

A measure of the energy of random motion in a substance's molecules.
