Ozone Layer and Depletion

What is the ozone layer?

• A layer of harmful gases in the atmosphere

• A layer of oxygen molecules in the stratosphere

• A layer of smog in the troposphere

• A layer of carbon dioxide in the mesosphere

How is the ozone layer being destroyed?

• By emissions of ozone depleting substances

• By volcanic eruptions

• By deforestation

• By solar flares

Where is the ozone layer located?

• In the troposphere

• In the mesosphere

• In the stratosphere

• In the thermosphere

What is the main effect of ozone depletion?

• Increased skin cancer cases

• Increased rainfall

• Decreased global temperature

• Decreased crop yields
