Drainage Basin System - FREE KS3 Geography Worksheet

🌧️ Find out how rain becomes river water in this free KS3 Geography worksheet on the drainage basin system — no preparation needed, just download and use. Perfect as a lesson starter, homework task, or quick revision activity for 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.

📝 Three questions, 13 marks in total: a 2-mark multiple choice question on the main input to a basin; a 5-mark word bank gap fill on interception, throughfall, stemflow, transpiration and outputs; and a 6-mark written task explaining why a basin is an open system. A full answer key is included. Comes as a PDF and an editable Word file (DOCX).
