rivers.

These pictures show views from river valleys in the
UK.
|
1.
Where rivers are fast flowing they cut down rapidly. This leads
to the creation of steep-sided valleys, known as 'v' shaped
valleys. This is the valley of Crowden Brook, near Edale in
Derbyshire.
|
2.
This is the Ashop valley in the Peak District. The river is not
flowing so quickly, and it has begun to use its energy to widen its
steep sided valley. As the river meanders it undercuts slopes
along the sides of the valley to create a flat floor.
|
3.
This is a meander in the River Esk in the Lake District. On the
inside of the bend is the deposition of sand and gravel known as the
'slip off slope'. The river occupies a channel on the outside of
the bend and is undercutting the bank at this point.
|
4.
In Wensleydale, the River Ure crosses a mixture of hard limestone and softer
shale.
The harder limestone beds form rapids in the river channel.
|
5.
Teesdale is in Northern England. The River Tees crosses a hard rock bed known as
the 'Whin Sill', which was formed from a volcanic eruption. The resistant
Dolerite rock of the Whin Sill forms an
impressive waterfall known as 'High Force'.

6.
This is a view of the Humber estuary near to the Humber
Bridge. The valley floor is wide and the gradient very slight. The
river is tidal, and big enough to allow small ships to use it. The river
is 1.5km wide at this point.
