HomeHomework Helpenvironmental-scienceOzone Depletion

Ozone Depletion

Ozone depletion refers to the reduction of the ozone layer in the Earth's stratosphere, primarily caused by the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances. This phenomenon leads to an increase in ultraviolet (UV) radiation reaching the Earth's surface, which can have harmful effects on human health and ecosystems.

Overview

Ozone depletion is a significant environmental issue caused primarily by human-made chemicals like CFCs. These substances break down ozone molecules in the stratosphere, leading to a thinner ozone layer that allows more harmful UV radiation to reach the Earth's surface. This increase in UV exposure ...

Key Terms

Ozone
A molecule composed of three oxygen atoms, found in the Earth's stratosphere.

Example: Ozone is crucial for blocking UV radiation.

CFCs
Chlorofluorocarbons, chemicals used in refrigeration and aerosol sprays that deplete ozone.

Example: CFCs were widely used in air conditioning systems.

UV Radiation
Ultraviolet radiation from the sun that can cause skin damage and cancer.

Example: Increased UV radiation can lead to sunburn.

Stratosphere
The second layer of Earth's atmosphere, where the ozone layer is located.

Example: Commercial jets fly in the lower stratosphere.

Montreal Protocol
An international treaty designed to phase out substances that deplete the ozone layer.

Example: The Montreal Protocol has led to a significant reduction in CFC use.

Halons
Chemicals used in fire extinguishers that also contribute to ozone depletion.

Example: Halons are being phased out due to their environmental impact.
