  2. It shields Earth from particle radiation ✔

Why: Earth's magnetic field forms a protective bubble called the magnetosphere. It deflects charged particles from the Sun and deep space, and it helps keep the solar wind from wearing away our atmosphere.

Huh, didn't know that: The solar wind squashes the magnetosphere on the side facing the Sun.
