Energy Transfer

AtmosphereGlobal

WarmingDid you

read?Say What?

Energy that flows from an object of higher temperature to an object of lower temperature

HEAT

50 % of the sun’s energy is either directly or indirectly _____________ by Earth’s surface.

ABSORBED

Heat is transferred through the atmosphere in three ways. Name them.

RadiationConvectionConduction

What type of energy from the sun warms your face?

RADIANT

The transfer of energy when molecules bump into each other. This is the reason why your feet get hot on the sandy beach on a hot August day.

CONDUCTION

Earth’s early atmosphere contained ________ and _______ from erupting volcanoes.

Carbon Dioxide and

Nitrogen

What protective layer in the atmosphere allowed green plants to flourish?

OZONE LAYER

Describe the composition of Earth’s atmosphere.

NitrogenOxygenArgon

Carbon DioxideTrace elements

Solid, liquid, and gas particles

True or false. There are solid particles in the atmosphere. If it’s true, explain the statement. If it’s false, explain why it is false.

True. There are pollen and dust particles in the

atmosphere.

Put the layers of the atmosphere in the right order starting with the one closest to Earth’s surface.

TroposphereStratosphereMesosphere

ThermosphereExosphere

Name a greenhouse gas.

MethaneCarbon Dioxide

Water vapor

Too much exposure to ____________ radiation can cause skin cancer.

ULTRAVIOLETRADIATION

Once used in refrigerators, air conditioners, and hair sprays, these molecules can break up ozone molecules in the atmosphere.

CFCs or

Chlorofluorocarbons

Which part of a CFC molecule could break apart a molecule of ozone?

The chlorine atom

Explain why during the day the radio only receives AM

radio stations from a nearby city, while at night, you are able to hear AM

radio stations from a distant city.

Ionosphere – The layer of electrically-charged particles between the mesosphere and the thermosphere.

Heated air at the equator is _____dense than the cold air near the Poles.

LESS

Warmer, less dense air will(rise above or sink below)colder, denser air.

RISE ABOVE

This effect is caused bythe rotation of earth which results in air and waterappearing to move rightnorth of the equator and to the left south of the equator.

Coriolis Effect

Daily Double:

The windless, rainy zone by the equator is known as the

________.

DOLDRUMS

Jet pilots and even airlines take advantage of these strong winds blowing near the top of the troposphere.

JET STREAMS

These winds are created when solar radiation warms the land more so than the water.

Sea breezes

Why doesn’t life exist on Mars or Venus?

Venus – gases in its atmosphere trap the sun’s energy resulting in temperatures being extremely hot on its surface.

Mars – extremely cold. Atmosphere is too thin to hold in the sun’s energy.

True or False.

The water cycle affectsEarth’s climate.

TRUE

DAILY DOUBLE

Water vapor turns into liquid water

CONDENSATION

Describe how altitude affects the amount of atmospheric pressure you experience.

The higher in elevation you go, there is less atmospheric pressure because there are

less air molecules.
