The document summarizes key landforms of erosion and deposition found in the Lake District, which was affected by past glaciation. It identifies corries, aretes, and troughs as major erosional landforms, such as Red Tarn, Striding Edge, and Grisedale. Depositional landforms discussed include erratics, drumlins formed parallel to glacier flow, and different types of moraines (terminal, lateral, and medial moraines). Ground moraines are also mentioned as piles of varying rock types and sizes.
