From which of the following does the ozone layer protect the earth? (A) A) Gamma radiation from the sun (B) B) Nuclear radiation from the Van Allen belt (C) G) Ultraviolet radiation from the sun (D) D) Infrared radiation from the sun

The ozone layer acts like Earth's sunscreen, primarily shielding us from harmful ultraviolet (UV) radiation emitted by the sun. This layer, composed of ozone (O₃) molecules, absorbs about 97% to 99% of the sun’s harmful UV rays, which can lead to skin cancer, cataracts, and other health issues. So when you’re out enjoying the sunshine, remember that this invisible barrier is working hard to keep you safe! In addition to its protective qualities, the ozone layer is crucial for maintaining ecological balance. It helps regulate the Earth's temperature by reflecting some of the sun's energy back into space. Without a healthy ozone layer, the increase in UV radiation could also disrupt ecosystems, affecting plant growth and marine life, leading to significant consequences for food chains and biodiversity. So, here's to protecting our planet’s superhero!
