U-shaped Valley - This a valley which was V-shaped but has
been eroded by ice. The valley sides are steeper and the
valley floor flatter after the ice melts. Hence the name
The video below shows High Cup, a u-shaped valley in the North Pennines.
Truncated Spurs - These are spurs which have been cut through
by ice, e.g. Nant Francon Valley, Snowdonia.
Hanging Valleys - These occur when glaciers at higher levels
than the main valley didn't experience such powerful erosion.
Tributary streams enter the valley as waterfalls from hanging
Ribbon Lakes - These are lakes found in U-shaped valleys,
e.g. Lake Windermere, Lake District. Drumlins
- These are hills shaped like eggs! (see diagram below).
Drumlins are blunt at one end and tapered at the other. Drumlins
are found in swarms called 'basket of eggs' topography. This is because they look like eggs in a basket!
They are formed when ice is moving forward, but is also
melting. The ice deposits boulder clay and till when it
comes across a small obstacle (e.g. small rock outcrop).
Most material is deposition the 'up stream' end of the drumlin.
The down stream end is shaped by the ice.
