How ozone layer protects us from ultraviolet?

Answer 1

Life on Earth depends in part on a thin shell of gaseous ozone that stretches from about 10 to 25 miles above our heads, encompassing the planet like an invisible, protective shield. At this altitude, it lies well above the height at which normal commercial aircraft fly, and far beneath the orbital paths of spacecraft. The ozone layer is the main barrier between us and the hazardous ultraviolet radiation that streams toward the Earth, day in and day out, from the burning surface of the Sun. Ozone--a form of oxygen--is selective in what it takes from sunlight: screening out, through a process of atomic absorption, only the more energetic ultraviolet rays while allowing the visible light and the warm infrared to pass through, untouched

Answer 2

The ozone layer absorbs and scatters the majority of the Sun's harmful ultraviolet (UV) radiation, particularly UVB and UVC rays, before they reach Earth's surface. This helps protect humans and other organisms from experiencing negative health effects such as skin cancer, cataracts, and impaired immune function caused by overexposure to UV radiation. Without the ozone layer acting as a shield, these harmful UV rays would reach the surface and pose a significant risk to life on Earth.

Answer 3

It absorbs UV radiation from the sun, protecting us from skin cancer and sunburn.

Answer 4

Ozone layer absorbs the UV rays. These UV rays are fatal for life on earth.

Answer 5

Ozone layer protects us from UV rays. It blocks most of them.

Answer 6

Ozone absorbs the UV rays. It is present in the stratosphere.

Answer 7

Ozone layer protects us from harmful UV rays. They are ozone molecules in a pool in atmosphere.
