Chapter 18 - Atmosphere

5 Layers

100

You would find find the ozone layer here

Stratosphere

200

This is the hottest layer in our atmosphere with temperatures reaching 1250 C

Thermosphere

300

This is the outer layer of our atmosphere where the temperature can change

Exosphere

400

This layer is where the earth’s weather occurs

Troposphere

500

This is the coldest layer of the atmosphere with temperatures going down to - 90 C

Mesosphere

Ozone Layer

100

The ozone layer protects the earth from this harmful type of solar energy

Ultraviolet Light (UV light)

200

The ozone is thinning over this continent

Antarctica

300

There are this many oxygen atoms in an ozone molecule

three (O3)

400

This protocol was introduced in 1978 to ban the use of ozone-depleting substances such as CFC and Freons.

Montreal Protocol

500

True or False

Ozone is harmful to breathe in, but it protects us when it is high in the atmosphere

True

Special Layers

100

The composition of this layer involves a mixture of gases such as carbon dioxide, nitrogen, oxygen, etc.

Homosphere

200

The composition of this layer has gases that are stacked on top of each other and do not mix.

Heterosphere

300

This layer plays a critical role in radio communication by reflecting signals for long-distance transmission.

Ionosphere

400

These lights form when protons and electrons from solar winds collide with gas molecules in our atmosphere, creating a beautiful sight to see

Northern /Southern Lights

500

This layer protects the earth from solar winds that come from the sun

Magnetosphere

Objects in the Atmosphere

100

Mount Everest (10 km)

Troposphere

200

International Space Station (450 km)

Thermosphere

300

Fighter Jet (20 km)

Stratosphere

400

Hubble Space Telescope (550 km)

Exosphere

500

Burning Meteors (70 km)

Mesosphere

Solar Energy

100

This term describes the steady flow of energy from the sun through space that reaches the earth

Solar Constant

200

This form of heating involves a transfer of energy with indirect contact, such as a campfire heating.

Radiation

300

These are two greenhouse gases that are trap the sun's heat in our atmosphere

Carbon Dioxide and Water Vapor

400

This form of heating involves a transfer of heat energy with direct contact, such as a pan on a fire.

Conduction

500

Most of the sun’s energy is this form of wavelength

Infrared Wavelengths
