**Step-by-Step Solution:** 1. **Protection from UV Rays:** - The atmosphere acts as a protective layer for the Earth by blocking harmful ultraviolet (UV) rays emitted by the sun. These rays can cause serious health issues such as skin cancer and cataracts in humans and can be detrimental to other organisms as well. 2. **Maintaining Temperature:** - The atmosphere helps in regulating the Earth's temperature. It keeps the temperature relatively constant, preventing extreme fluctuations that could be harmful to living organisms. ...
