What is the ozone layer, and how does it work?

• The ozone layer is a protective shield made entirely of oxygen around the Earth. It works by reflecting all the sun's rays into space, keeping the planet cool and preventing sunlight from reaching the surface.

• The ozone layer is a thin part of the Earth's atmosphere that stores most of the planet's heat and is responsible for weather patterns. It circulates warm air around the globe and ensures consistent temperatures.

• The ozone layer in Earth's atmosphere contains a high ozone concentration (O3). It absorbs most of the sun's harmful ultraviolet (UV) radiation, protecting living organisms on Earth from potential damage. The layer is found mainly in the lower portion of the stratosphere, from about 10 to 30 kilometers above Earth's surface.
