Prior Knowledge Questions (Do these BEFORE
using the Gizmo.)
1. The image above shows a raging mountain river in full flood. What do you think is making
the water brown in color?
2. What impact do you think the flooding river will have on the surrounding landscape?
Gizmo Warm-up
If you stand by the bank of a river, it may seem that very little is
happening. But over thousands and even millions of years,
rivers can have a profound effect on the landscape. In the River
Erosion Gizmo, you will see how rivers move materials and how
they affect landscapes.
To begin, check that Mountain stream and Short-term erosion are selected. The Gizmo
shows a typical stream that is moving through a hilly area.
1. The two movie cameras
allow you to observe different parts of the stream up close.
Click on the left movie camera. What do you see?
2. Sediments
small rock fragments such as sand or pebbles. What evidence do you see
that sediments are being transported?
3. Now select the right movie camera to see the bank of the mountain stream. What is
happening to sediments on the bank?

Expert Solution
Introduction
Floods occur due to excess water in the river, overflowing its bank. The flooding can be due to excess rainfall, cloudburst, melting of snow, sudden release of water from the reservoir.
