Introduction Geography Glaciation

Introduction Geography Glaciation Glaciated landscapes are formed by three main processes. These are:

Introduction Geography Glaciation Plucking is the ice freezing on to a jagged piece of rock and pulling it out as the ice continues to move downhill.

Introduction Geography Glaciation Abrasion happens when ice already has fragments of rock embedded in its base and these scrape at the rock surface.

Introduction Geography Glaciation Striations

Introduction Geography Glaciation Freeze- thaw is a form of physical weathering, common in mountains and glacial environments, caused by the expansion of water as it freezes.
