Draw a labelled diagram to show the layered structure of the atmosphere - HSC - SSCE Chemistry - Question 29 - 2012 - Paper 1

Start with a vertical representation of the atmosphere.

• Divide the diagram into its main layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
• Label these layers clearly.

Indicate pollutants in appropriate layers:

• In the Troposphere, label Carbon Monoxide (CO), which negatively impacts air quality.
• In the Stratosphere, label Ozone (O₃), which has both beneficial and detrimental effects depending on its altitude.

Identify sources of the pollutants:

• For Carbon Monoxide, note vehicle emissions and industry as primary sources.
• For Ozone, indicate industrial emissions and reaction of sunlight with pollutants as sources.

Ensure clarity by adding arrows or descriptions if necessary to highlight the detrimental impacts each pollutant has in its respective layer.
