Water safety and the ocean, sentence 15

Polystyrene, the light white foam used in packing, is mostly trapped air bubbles, so it floats almost on top of the water, and bits of it pollute the sea for years.

Who acts: Polystyrene, bits · What happens: use, trap, float, pollute · To what, where: light white foam, packing, Polystyrene, top, sea

This is a sentence of the lesson «Water safety and the ocean» 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 (Polystyrene, bits), 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.
