1. The charged particles from the Sun interact with Earth's intense magnetic field at the North and South Poles, making the sky glow in colors in the effect known as:
A.the Coriolis force.
B.the magnetosphere.
C.solar wind.
D.an aurora.
Explanation: energetic electrically charged particles (mostly electrons) accelerate along the magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light.
