Compasses and the magnetic Earth, sentence 4

The Earth's magnetic field also guides charged bits from the Sun down near the poles, where they make the air glow as the northern lights, and many birds can feel the field and use it to find their way.

Who acts: magnetic field, bits, many birds · What happens: guide, charge, make, feel, use, find · To what, where: charged bits, Sun, air glow, field, way

This is a sentence of the lesson «Compasses and the magnetic Earth» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (magnetic field, bits, many birds), what happens, when and where, as Mova's frames read it from the tree.

The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
