Drainage Basin Features - KS3 Geography Worksheet

A complete, no-prep 100-mark worksheet on drainage basin features — ready to use for lessons, homework, or revision with KS3 Geography students aged 11-14. A drainage basin is the whole area of land that drains into one river, bordered by a watershed, source, tributaries, confluences and a mouth.

Structured across three sections of progressive difficulty: Section 1 (30 marks) covers key definitions through six multiple choice questions, an eight-statement true or false table, and a fill-in-the-blank exercise on tributaries, confluences, mouths and estuaries. Section 2 (40 marks) builds understanding through short answer questions comparing tributaries and confluences, a written explanation of estuary ecosystems, an extended answer on reading Ordnance Survey maps, a matching exercise, definition writing, and a labelled diagram task. Section 3 (30 marks) challenges students with extended writing tracing a raindrop’s journey from source to sea, explaining why a single ridge can split rainfall between two seas, and evaluating whether OS maps are the best way to study a river system. A full answer key with detailed marking guidance is included.

Also available: a companion extension pack with four enrichment activities, or save £1 with the complete lesson bundle — both listed on the iNewittAll TES store.

Google Classroom ready.
