Deserts, sentence 0

A desert is a place where very little rain or snow falls, usually less than about 250 mm a year, so a desert does not have to be hot or sandy: icy Antarctica is the biggest desert on Earth.

Who acts: desert, little rain, icy Antarctica · What happens: be, fall, not have · To what, where: place, biggest desert, Earth

This is a sentence of the lesson «Deserts» of the geography 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 (desert, little rain, icy Antarctica), what happens, when and where, as Mova's frames read it from the tree.
