Living with friction: oil, wheels and grip, sentence 13

A spacecraft coming home glows red hot mostly because the air in front is squeezed and heats up, so it needs a heat shield.

Who acts: spacecraft, air · What happens: come, glow, squeeze, heat up, need · To what, where: air, heat shield

This is a sentence of the lesson «Living with friction: oil, wheels and grip» 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 (spacecraft, air), what happens, when and where, as Mova's frames read it from the tree.

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R7-rel-agree ×1. 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.
