1. The Journey of a River

2. This picture shows the complete journey of a river, from the source to the sea. Let’s have a look at this journey more closely.

3. The place where a river starts is called the source . The source can be in hills or mountains. Sometimes a river has more than one source.

4. Sometimes, as the water travels down, it hits a layer of rock. This makes a waterfall . Close up!

5. Small streams that join the river are called tributaries .

6. Large ‘s’ shaped bends and curves in the river are called meanders . Close up!

7. Sometimes, as the river flows down, lakes can form in hollows in the ground. This river does not have a lake, but there is some marshy ground near the meanders.

8. Eventually the river flows into the sea. This is called the mouth of the river. If the mouth of the river is very wide it is called an estuary .
