The two main layers of the atmosphere that provide protection are the ozone layer (located in the stratosphere) and the ionosphere (part of the thermosphere).
- The ozone layer acts as an invisible shield, absorbing most of the sun's harmful ultraviolet (UV) radiation, which can cause skin cancer and other health problems.
- The ionosphere reflects radio waves, enabling long-distance communication.
These two layers of the atmosphere work together to protect us from harmful radiation and to support our communication systems.
