What is the ozone layer?

Back

A region of Earth's stratosphere that contains a high concentration of ozone (O3) and protects the planet from harmful ultraviolet (UV) radiation.

What is UV radiation?

Back

Ultraviolet (UV) radiation is a type of energy produced by the sun that can break down molecules in the atmosphere and is harmful to the ozone layer.

Front

What are halogens?

Back

A group of elements in the periodic table (Group 17) that includes fluorine, chlorine, bromine, iodine, and astatine, known for forming harmful chemicals that can deplete the ozone layer.

What is smog?

Back

A type of air pollution that is a mixture of smoke, fog, and chemical pollutants, often produced by ozone in the lower atmosphere.

How does the ozone layer benefit life on Earth?

Back

It absorbs the majority of the sun's harmful UV radiation, protecting living organisms from skin cancer and other health issues.

Front

What happens when the ozone layer is depleted?

Back

Increased UV radiation reaches the Earth's surface, leading to higher risks of skin cancer, cataracts, and harm to ecosystems.

Front

What are CFCs?

Back

Chlorofluorocarbons (CFCs) are man-made chemicals that were commonly used in refrigeration and aerosol sprays, known for their role in ozone depletion.

Front

What is atmospheric pressure?

Back

The force exerted by the weight of air above a given point, which decreases with altitude in the atmosphere.

Front

What is the stratosphere?

Back

The second layer of Earth's atmosphere, located above the troposphere, where the ozone layer is found.

Front

What role do mountains play in weather patterns?

Back

Mountains can force air to rise, leading to cooling and precipitation on the windward side, while creating dry conditions on the leeward side.
