The correct answer is C. Ultraviolet rays.
Ultraviolet rays are a type of electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. They are emitted by the sun and other sources, such as welding torches and tanning beds.
Ultraviolet rays can cause a variety of health problems, including skin cancer, cataracts, and immune system suppression. They can also damage plants and other living things.
The ozone layer is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation. It is located approximately 20 to 30 kilometers above Earth’s surface and is made up of ozone (O3), a molecule that contains three oxygen atoms.
The ozone layer protects life on Earth by absorbing ultraviolet radiation. Without the ozone layer, ultraviolet radiation would reach the Earth’s surface in much higher levels, causing a variety of health problems.
In the absence of the ozone layer, ultraviolet rays would enter the atmosphere and cause a variety of health problems. These problems include skin cancer, cataracts, and immune system suppression. Ultraviolet rays can also damage plants and other living things.
