How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to belt is drive.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Space physics

a doughnut-shaped region around a planet where charged particles are trapped by the magnetic field at high energy.

In space physics, a belt is a doughnut-shaped region around a planet where charged particles are trapped by the magnetic field and circle it at high energy. Van Allen and Frank (1959) mapped two such belts around the Earth from early satellite counters, an inner and an outer zone of electrons and protons held on magnetic field lines far above the surface. The referent is a population of particles occupying a region of near-Earth space, and the unit is particle flux at a given energy and distance, counted per second by a detector in orbit. It shares the word with a mountain range and a drive belt, but nothing here is solid or on the ground; the belt is a cloud of radiation, invisible and held in place by a field rather than by rock or tension.[1]
