Unit 5 Review

Mr. Snow shared the chart below with his students on the layers of the atmosphere. He asked the class to identify the layer of Earth’s atmosphere is closest to Earth and contains oxygen that organisms in the biosphere require to survive. Refer to the chart provided in the worksheet.

• Exosphere

• Stratosphere

• Thermosphere

• Troposphere

Based on the data table above, which of the following would be the best conclusion about how temperature changes in the atmosphere?

• As temperature increases in the atmosphere, altitude increases in every layer of the atmosphere.

• As altitude increases in the atmosphere, temperature increases in each layer of the atmosphere.

• As temperature increases in the atmosphere, altitude can either increase or decrease depending on the layer.

• As altitude increases in the atmosphere, temperature can either increase or decrease depending on the layer.
