How has glaciation shaped uk landscapes?
Glaciers made U shaped valleys and left behind features like waterfalls
How have tectonic process help to form UK landscapes?
When parts of a tectonic plate was lifted up more than the other, they left landscapes with higher and lower parts.
How has geology helped to shape U.K landscapes?
When fish died in the tropical seas around the UK many years ago, they left their skeletons behind, so when other fish died their skeletons etones land on top of theirs, gradually forming layers. Some of these layers deposited on top of limestone and formed the peaks of mountains like the Pennines.
