Amanda draws a picture showing four layers of Earth's atmosphere. She draws clouds in the mesosphere, a jet airplane in the stratosphere, an orbiting satellite in the thermosphere, and ozone in the troposphere. Which two mistakes did she make in her picture?

• Ozone should have been drawn in the

  stratosphere

• Clouds should have been drawn in the

  troposphere.

• Orbiting satellites should have been drawn in the

  mesosphere.

• Jet airplanes should have been drawn in the

  thermosphere

• Jet airplanes and clouds should have been

  drawn in the mesosphere

Which atmospheric layer is very hot and contains "light showers" known as auroras?

• stratosphere

• exosphere

• mesosphere

• thermosphere

Which layer of the atmosphere contains the highest concentration of ozone?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere
