Long profiles and valley cross sections
The long profile of a river shows a steep gradient at the source, gradually becoming lower and less steep until the gradient is almost nil near to sea level.
Case Study: The Afon Glaslyn, Wales, United Kingdom.
Use Google Image Search to find images of each of the locations marked on the case study long profile diagram above.
Paste the images into an application such as Google Slides to produce a description of how the gradient and valley cross section changes between Lyn Llydaw and the sea.
Give reasons for all the changes that you can see in the images.
