The distance above sea level.

The relatively thin envelope of gasses that surround the planet.

The movement of air parallel to Earth’s surface.

10-50 km in altitude and contains most of the ozone layer.

Layer with the lowest density of air that is considered Earth’s boundary with space.  This layer absorbs radiation from the Sun and is extremely hot, but feels very cold.

0-10 km in altitude and contains all of Earth’s weather.  Contains 80% of the atmosphere by weight.

50-85 km in altitude and protects Earth from most meteoroids.

The layer closest to the Earth is...

The layer farthest from the Earth is...

The‌ ‌atmosphere is made up of mostly what TWO gasses?

What‌ ‌happens‌ ‌to‌ ‌the‌ ‌air‌ ‌pressure‌ ‌as‌ ‌you‌ ‌go‌ ‌up‌ ‌in‌ ‌altitude?‌

Which is NOT a way that heat is transferred to and from the Earth?

What‌ ‌causes‌ ‌global‌ ‌winds?‌

The percent of water vapor in the air as compared to the maximum amount of water vapor the air can hold at a particular temperature.

When molecules of a liquid are heated causing the molecules to speed up and become a gas.

The temperature at which condensation occurs.

Any form of water that falls from clouds to Earth’s surface.

Occurs when a gas (water vapor) changes to a liquid (liquid water) when it loses enough energy.

A measure of the amount of water vapor in the air.

Describes the way that certain liquids move through Earth’s systems.

Which‌ ‌step‌ ‌of‌ ‌the‌ ‌water‌ ‌cycle‌ ‌is‌ ‌it‌ ‌when‌ ‌a‌ ‌puddle‌ ‌on‌ ‌the‌ ‌sidewalk‌ ‌gets‌ ‌smaller‌ ‌over‌ ‌time?‌

If‌ ‌the‌ ‌humidity‌ ‌is‌ ‌at‌ ‌75%‌ ‌what‌ ‌does‌ ‌this‌ ‌indicate?‌

Occurs‌ ‌when‌ ‌water‌ ‌vapor‌ ‌changes‌ ‌into‌ ‌liquid‌ ‌water.‌

What‌‌ TWO ‌items‌ ‌provide‌ ‌energy‌ ‌for‌ ‌the‌ ‌water‌ ‌cycle?‌

The boundary where air masses meet.

A weather system with high atmospheric pressure at its center, around which air slowly circulates in a clockwise direction (northern hemisphere).  They are associated with calm, fine weather.

A huge body of air that has similar temperature, humidity and air pressure throughout.

A high-speed band of winds about 6-14 km above Earth.

A system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) directional spin.

This forms when cold and warm air masses meet, but neither one can move the other.

This forms when a cold air mass runs into a warm air mass.  The cold, dense air mass slides under the warmer air mass.

This forms when a fast-moving warm air mass overtakes a slower-moving cold air mass.

This forms when a warm air mass gets caught between two cold air masses.

What‌ ‌type‌ ‌of‌ ‌air‌ ‌mass‌ ‌is‌ ‌most‌ ‌likely‌ ‌to‌ ‌form‌ ‌over‌ ‌the‌ ‌Atlantic‌ ‌Ocean‌ ‌near‌ ‌the‌ ‌equator‌?

What‌ ‌type‌ ‌of‌ ‌air‌ ‌mass‌ ‌is‌ ‌cool‌ ‌and‌ ‌dry?‌

What‌ ‌are‌ ‌the‌ TWO ‌major‌ ‌causes‌ ‌for‌ ‌moving‌ ‌air‌ ‌masses‌ ‌in‌ ‌‌North‌ ‌America‌?‌

These orbit high above Earth collecting data as well as images of Earth’s surface and atmosphere.

These carry instruments for collecting weather data high into the atmosphere.

These are located in many locations and can gather real-time weather data.

A line on a weather map connecting points having the same atmospheric pressure at a given time.

A line on a weather map connecting points having the same atmospheric temperature at a given time.

These process weather data quickly.

What type of front does this symbol indicate?

A localized storm often accompanied by heavy rain, frequent thunder and dangerous lightning.

A cyclone with wind speeds of more than 70 miles per hour that can last a week or more.

An extremely fast spinning column of air extending from the base of a thunderstorm to Earth’s surface.

A long period with little or no rainfall.

A violent disturbance in the atmosphere.

The most deadly part of a hurricane.  It is the  rising of the sea as a result of atmospheric pressure changes and wind associated with a storm.

An overflowing of water in a normally dry area.

It is the rising of the sea as a result of atmospheric pressure changes and wind associated with a storm.

Which‌ ‌type‌ ‌of‌ ‌storm‌ ‌always‌ ‌forms‌ ‌over‌ ‌and‌ ‌pulls‌ ‌energy‌ ‌from‌ ‌a‌ ‌large‌ ‌body‌ ‌of‌ ‌water?‌

What type of storm is associated with the term “lake effect”?

Is the nickname of the area of the United States that receivess 75% of the world's torandoes.
