Formation of a Ribbon Lake
Formation of an Hanging Valley

Important!!
When explaining the formation of Glacial features you NEED to discuss the processes involved. This is a very easy way to pick up marks! As you get a mark for naming the process and a mark for explaining how the process works. You get credited for up to 2 glacial processes per feature.
For the erosional features, all of the processes are the same. Regardless of the erosional feature make sure you discuss Abrasion and Plucking!
Formation of a Ribbon Lake
Formation of a Ribbon Lake
REMEMBER!
When answering these as a full Higher Question you need to explain the processes which are involved in these formations. A well-explained process can gain you 2 marks, 1 mark for naming the process and 1 mark for explaining the process, but you need to have both to gain both marks.
The same goes for every process term you say
Ullswater, Lake District - Ribbon Lake
These features are straight forward and your task is simply to try and understand the processes which explain how they form

Write the formation of a U-Shape Valley & 2 erosional processes
If there is a banding of hard rock and soft rock transecting the u-shape valley the soft rock is eroded easier and deeper
the eroded soft rock forms a basin in between the bands of hard rock
Moraine may be deposited by the glacier inside the u-shape valley
this could act as a dam blocking water in forming a long thin ribbon lake
A very well known ribbon lake is Ullswater in the Lake District (Also: Lake Windemere, Loch Ness and Loch Lomond)

for erosional processes, you can get an extra mark for a named example of the feature!

Explanation
Write about the formation of a glacier & 2 erosional processes
A small glacier flows down from a corrie to join the main glacier in a larger U-Shaped Valley
This smaller glacier doesn’t erode as deep as the main valley glacier
After the ice melts a tributary valley is left hanging above the main valley
River or stream returns to the valley and flows over the hanging valley forming a waterfall.
The waterfall creates an alluvial fan of deposition.
