Question:

What is the ozone layer? Why is it important?

Expert Verified Solution:

The ozone layer is a region of the Earth’s stratosphere that contains a high concentration of ozone (O₃) molecules. Positioned approximately 10 to 30 miles above Earth’s surface, this layer plays a crucial role in absorbing the majority of the Sun’s harmful ultraviolet (UV) radiation, particularly UV-B and UV-C rays. By filtering out these harmful rays, the ozone layer helps protect living organisms from increased risks of skin cancer, cataracts, and other health issues. Additionally, it safeguards ecosystems, including marine and terrestrial life, from UV-induced damage. The preservation of the ozone layer is essential for maintaining the balance and health of both human and environmental systems.
