Also it has arrows showing glacier movement and where striations can be found. Add arrows to show glacier movement and where striations can be found. Add details of plucking and abrasion to your diagram. Label zones of accumulation and ablation. Glacial Landforms Glacier movement and erosion has produced a range of distinctive landforms in upland Britain.
Glaciers develop from severely compressed snow in deep hollows in mountains called corries .
As they increase in size, gravity forces them to move down the valley, making it deeper and wider. The U-shaped valley produced is called a trough and will often have a ribbon lake in the bottom. Limestone Landforms Limestone is a unique rock. There are vertical cracks in these strata called joints. Limestone is pervious, so while water runs on impermeable rock, it runs through the joints and bedding planes of the limestone.
