Which function is performed by Earth’s magnetic field?
A
It is responsible for the majority of Earth’s heat flow from the interior to the surface.
B
It deflects and traps charged particles from the solar wind, reducing harmful radiation at Earth’s surface.
C
It produces most of Earth’s gravitational attraction on objects near the surface.
D
It directly causes the daily cycle of ocean tides by exerting a strong magnetic pull on seawater.
