The ozone layer absorbs most of the incoming _____ radiation.

• A. infrared
• B. ultraviolet
• C. gamma
• D. microwave

Answer: (B)

Verified step by step guidance

1. Understand that the ozone layer is a part of Earth's atmosphere that plays a crucial role in protecting living organisms from harmful radiation.
2. Recall the types of electromagnetic radiation: infrared, ultraviolet, gamma, and microwave, each with different energy levels and effects.
3. Recognize that ultraviolet (UV) radiation has higher energy than infrared and microwave radiation but lower than gamma rays.
4. Know that the ozone layer specifically absorbs most of the ultraviolet radiation, preventing it from reaching the Earth's surface and causing damage to living cells.
5. Conclude that the correct answer is ultraviolet radiation because it is the type of radiation the ozone layer effectively absorbs.
