This document provides information about how rivers change from their source to mouth, including definitions of river terms and stages. It discusses the upper, middle, and lower stages of a river and defines factors like erosion, gradient, depth, velocity, width, volume, and landforms. It also examines the river drainage system and provides examples about the River Severn and its source, upper course, middle course, and lower course.
Lesson 13a he river from source to mouth
- 1. 25 November, 2014 How do rivers change from their source to the mouth? Check that you have made two predictions: Write two sentences for each: – Name size, height and what you’d see. – What will the land be used for?

Gradient Steepness of a slope Depth How deep a river is, measured in centimetres Velocity The speed and direction of a river, measured in m/sec Width How wide a river is, measured in meters Volume How much water is discharged by the river, measured in cumecs Landforms Distinctive features found along a river – e.g. waterfall.
- 8. What is the river drainage system? Starter: Write a description what the start of the River Amazon looks like. The Amazon – the world’s greatest river – which follows the route through the Earth’s largest forest, as the most bio-diverse habitat on the planet and is home to some of the most remote tribes on Earth.
- 10. Source: Where a river starts

- 16. Tributary: A small river that flows into a large river Confluence: The point where two rivers meet
- 17. The Middle course of the River Severn 2
- 18. Mouth: the end of a river where it flows into a lake or the sea
- 19. The mouth Describe the landscape and landforms Describe how the river and land is used
