The Earth belts are known as Van Allen belts as their discovery is credited to James Van Allen. These two belts are the inner an Allen belt and the outer Allen belt.
Van Allen belts are caused by deflection of charged particles. they are located in the inner region of the Earth's magnetosphere. these belts trap energetic electrons and protons.
The inner belt contains high concentrations of electrons and energetic protons, which have been trapped by strong magnetic fields in the region, the outer belt on the other hand contains high energy electrons trapped by the magnetosphere.
