keyterm- ozone

Answer 1

Ozone is a gas molecule composed of three oxygen atoms bonded together (O3). It is found in the Earth's stratosphere, where it plays a crucial role in protecting the planet from the sun's harmful ultraviolet (UV) radiation by absorbing and blocking it. Ozone is also present in the lower atmosphere, where it can be both beneficial and harmful. Ground-level ozone, formed when pollutants from vehicles and industrial sources react with sunlight, is a major component of smog and can have harmful effects on human health and the environment. However, ozone also plays a beneficial role in the upper atmosphere by reducing the effects of greenhouse gases and helping to regulate the Earth's temperature.
