In summary, the radiation belts are a doughnut-shaped region around the Earth's magnetic equator that contains electrons and protons. These particles are supplied by cosmic rays and the solar wind. The protons are located in the lower region compared to the electrons due to their higher energy and ability to penetrate the Earth's magnetic field.

Hello,
the radiation belts consist of electrons and protons that are trapped in a doughnut-shaped region centered around the magnetic equator.This region extends from a few hundred kilometers above the Earth to 48,000 to 64,000 km (30,000 to 40,000 mi).
The electrons and protons are supplied by cosmic rays and by the solar wind, a continuous stream of charged particles—mainly electrons and protons—emanating from the sun.

The question here is why the position of the proton is in lower region compare to electron? Is this because of the mass difference?

Thx

I'd say that is because the protons of the inner belt are cosmic rays that collide against the magnetic field of earth, and you know that cosmic rays are superenergetic, so they have more capability of penetration that the electrons of the outer belt, that are just plasma captured by the Earth magnetosphere
 

What are Van Allen Radiation Belts?

The Van Allen Radiation Belts are two doughnut-shaped regions of high-energy particles that surround the Earth, discovered by James Van Allen in 1958. They are held in place by the Earth's magnetic field and extend thousands of kilometers into space.

How were the Van Allen Radiation Belts discovered?

The Van Allen Radiation Belts were discovered by James Van Allen and his team of scientists in 1958 using data from the Explorer 1 satellite. They were the first to observe and document the existence of these high-energy particle regions surrounding the Earth.

What types of particles are found in the Van Allen Radiation Belts?

The Van Allen Radiation Belts contain a variety of particles, including protons, electrons, and ions. These particles are mostly derived from the solar wind, which is a stream of charged particles released by the Sun.

What is the significance of the Van Allen Radiation Belts?

The Van Allen Radiation Belts play a crucial role in protecting the Earth from harmful cosmic radiation. They act as a shield, trapping and deflecting high-energy particles that could be harmful to life on Earth. They also play a role in the dynamics of Earth's magnetosphere.

How do the Van Allen Radiation Belts affect human space exploration?

The Van Allen Radiation Belts pose a potential hazard for astronauts and spacecraft passing through them. High levels of radiation can damage electronic equipment and pose a risk to human health. Therefore, understanding and monitoring the Van Allen Radiation Belts is essential for safe human space exploration.
