How do rivers shape the land BBC?

River landscapes change as you go downstream from the source to the mouth. In the upper course of a river the altitude is high and the gradient is steep. In the middle course, the river meanders through gentle gradients. In the lower course, the river flows over flat land.

What are the river processes?

Erosion – the wearing away of the land and the stones carried in the river. Transport – the movement of rocks, sand, and silt by the river. Deposition – the dumping of rocks, sand and silt wherever the river slows down.

What are the 5 landforms created by rivers?

Remember to include river erosion processes keywords from last lesson in your explanation!

• UPPER COURSE. V-shaped Valleys, Interlocking Spurs, Gorges & Waterfalls
• MIDDLE COURSE. Meanders & Oxbow lakes.
• LOWER COURSE. Floodplains & Deltas

What are the different river landforms?

Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.

How are the landforms of a river changed?

River landforms: overview The processes of erosion and deposition create different river landforms. River landscapes change as you go downstream from the source to the mouth. In the upper course of a river the altitude is high and the gradient is steep.

What are the three main processes that occur in a river?

There are three main types of processes that occur in a river. These are erosion, transportation and deposition. All three depend on the amount of energy there is in a river. The energy in a river causes erosion.

Why does a river form a V shaped valley?

When a river is near its source, it often develops a V-shaped valley as the river erodes down (this is called vertical erosion). At the same time, weathering breaks up material on the valley slopes. Weathered material from the valley sides gets deposited in the river.

What are the features of the upper course of a river?

River landforms can be divided into upper, middle and lower course features. These include steep V-shaped valleys, oxbow lakes and flood plains, respectively. Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges.
