Mercury, sentence 9

Mercury's daytime surface reaches about 430 degrees Celsius, hot enough to melt lead, but at night it falls to about minus 180, because it has almost no atmosphere to keep heat in.

Who acts: daytime surface, surface · What happens: reach, melt, fall, have, keep in · To what, where: 430 degrees, lead, 180, atmosphere, heat

This is a sentence of the lesson «Mercury» of the space 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 (daytime surface, surface), 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): R5-strong ×4. 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.
