What mechanism forms the magnetospheres around several of the planets?
A) The gravitational force of attraction of the other planets on the planetary upper atmosphere
B) The very rapid spin of these planets,spinning the atmosphere outward
C) Repulsion of solar electromagnetic radiation by the planetary magnetic field
D) Repulsion of the solar wind by the planetary magnetic field

Question

Quizplus · Accepted Answer

The magnetospheres around several planets, including Earth, Jupiter, Saturn, Uranus, and Neptune, are formed by the repulsion of the solar wind by the planetary magnetic field. The solar wind consists of charged particles and radiation that are constantly emitted by the Sun, and the magnetic fields of these planets deflect and trap the solar wind, creating an area of protection around the planet known as a magnetosphere.
