Try these first

1. 1.

   What is ozone and why is it important?

   Hint

   Think about the protective layer above us.

2. 2.

   What are CFCs?

   Hint

   Recall the compounds used in fridges and sprays.

3. 3.

   What is the main cause of ozone depletion?

   • Natural processes
   • CFCs
   • Increased volcanic activity

   Hint

   Think of products like sprays and refrigerators.

4. 4.

   True or False: Ozone depletion leads to an increase in the amount of UV radiation reaching the Earth's surface.

   • True
   • False

   Hint

   Consider what ozone protects us from.

5. 5.

   Evaluate the long-term effects of losing the ozone layer on global agriculture.

   Hint

   Consider how UV light directly impacts plant growth and development.

6. 6.

   Propose and evaluate policy measures that could mitigate ozone layer depletion.

   Hint

   Think about what governments could enforce to protect the ozone layer.
