What mechanism protects humans on Earth from harmful solar radiation?
Answer
The Earth's magnetic field and dense atmosphere
The Earth is surrounded by a dense atmosphere and a global magnetic field that collectively function as a protective shield. These layers filter out the vast majority of harmful electromagnetic radiation and charged particles ejected by the sun. As a result, the environment at the surface remains safe for life, as these natural barriers absorb or deflect the extreme ultraviolet and X-ray radiation associated with solar events.
