Drainage Basin System - KS3 Geography Worksheet

📘 A complete, no-prep 100-mark worksheet on the drainage basin system — ready to use for lessons, homework, or revision with KS3 Geography students aged 11-14.

A drainage basin is the area of land that a river and its tributaries collect water from. Geographers treat it as an open system, because water enters it as inputs and leaves it as outputs.

📝 Structured across three sections of progressive difficulty: Section 1 (30 marks) covers inputs, stores, flows and key terms through multiple choice, a true/false table and a word bank summary. Section 2 (40 marks) builds understanding through definitions, an input/output/store/flow table, and short answers on interception, fast and slow routes, surface runoff and dry-weather rivers. Section 3 (30 marks) challenges students with extended writing on flood risk, a new housing estate scenario and a two-basin comparison. A full answer key with detailed marking guidance is included. Comes as a PDF and an editable Word file (DOCX).
