absorbs visible light wavelengths.
The Correct Answer and Explanation is :
The correct answer is: absorbs most ultraviolet wavelengths.
The ozonosphere, also known as the ozone layer, is a crucial part of the Earth’s atmosphere. It is located in the stratosphere, approximately 10 to 30 miles above the Earth’s surface. The primary role of the ozone layer is to absorb the majority of the Sun’s harmful ultraviolet (UV) radiation, particularly UV-B and UV-C rays. These types of UV radiation can cause significant harm to living organisms, including skin cancer in humans, cataracts, and harm to marine life and plants. By absorbing these rays, the ozone layer helps to protect life on Earth from their damaging effects.
UV radiation can be categorized into three types: UV-A, UV-B, and UV-C. UV-A rays, the least harmful, are not significantly absorbed by the ozone layer. UV-B and UV-C rays are much more dangerous and are almost completely absorbed by the ozone. Without this natural protection, the Earth would experience far higher levels of UV radiation at the surface, leading to detrimental environmental and health impacts.
In addition to its role in shielding against harmful UV radiation, the ozone layer also indirectly affects the Earth’s climate. By absorbing UV radiation, the ozone layer warms the stratosphere, and this warming plays a role in the overall temperature regulation of the planet. However, the primary function remains its protective shield against UV radiation.
While the ozone layer may have some indirect effects on technology, such as affecting satellite communications or GPS signals, its most critical role is in protecting life from harmful UV radiation. Thus, the ozone layer is essential to maintaining life on Earth, especially by absorbing most UV wavelengths.
