Layers of the Atmosphere

Analyze and interpret data to compare and contrast the composition of Earth’s atmospheric layers (including the ozone layer) and greenhouse gases. Clarification statement: Earth’s atmospheric layers include the troposphere, stratosphere, mesosphere, and thermosphere.

• The troposphere contains the most greenhouse gases, while the stratosphere contains the ozone layer.

• The mesosphere is where most weather phenomena occur, and the thermosphere contains the ozone layer.

• The stratosphere contains the most greenhouse gases, while the troposphere contains the ozone layer.

• The thermosphere is where most weather phenomena occur, and the mesosphere contains the ozone layer.

Why are Tornados so hard to predict?

• Because they form quickly and unpredictably

• Due to their large size

• Because they occur only in specific regions

• Due to advanced warning systems

What data can be used to compare and contrast Earth's layers?

• Seismic wave data

• Weather patterns

• Ocean currents

• Animal migration patterns

The purpose of the Ozone Layer is to:

• absorb ultraviolet radiation from the sun

• trap heat in the Earth's atmosphere

• reflect sunlight back into space

• produce oxygen for the Earth

Explain how you can compare and contrast the layers of the atmosphere.

• By their temperature and composition

• By their color and size

• By their distance from the sun

• By their gravitational pull

The purpose of the ozone layer is to:

• absorb harmful ultraviolet radiation from the sun

• trap heat in the Earth's atmosphere

• reflect sunlight back into space

• provide oxygen for breathing

• 0 km

• 12 km

• 50 km

• 80 km
