mkuu labda ww ndo haujaisoma labda nikusaidie maelezo hayaHivi mkuu hata hiyo van allen belt ulijishughulisha kusoma ukajua ni nini kabla ya kuandika?
A radiation belt is a zone of energetic charged particles ,
most of which originate from the solar wind that is
captured by and held around a planet by that planet's
magnetic field . The Earth has two such belts and
sometimes others may be temporarily created. The
discovery of the belts is credited to James Van Allen , and
as a result the Earth's belts are known as the Van Allen
belts. Earth's two main belts extend from an altitude of
about 1,000 to 60,000 kilometers above the surface in
which region radiation levels vary. Most of the particles
that form the belts are thought to come from solar wind
and other particles by cosmic rays. [1] By trapping the
solar wind, the magnetic field deflects those energetic
particles and protects the Earth's atmosphere from
destruction.
The belts are located in the inner region of the Earth's
magnetosphere. The belts trap energetic electrons and
protons . Other nuclei, such as alpha particles , are less
prevalent. The belts endanger satellites
