© Boardworks Ltd of 5 Snow collects in a natural hollow on the side of a mountain. Over time, further snow collects in the hollow. This extra weight compresses the snow underneath, turning it into ice. The hollow is deepened and widened by the corrie glacier through the processes of abrasion and plucking. rock lip This overdeepening leads to an ‘armchair’ shape characteristic of a corrie and causes a ‘rock lip’ to be formed. How is a corrie formed?
© Boardworks Ltd of 5 Arêtes are ‘knife-edged’ ridges formed between two corries. Formation of an arête
© Boardworks Ltd of 5 Formation of a glacial trough
© Boardworks Ltd of 5 truncated spurs hanging valley misfit stream wide and flat valley floor steep valley sides What are the characteristics of a glacial trough? Interlocking spurs are truncated as the glacier cuts straight through the landscape. Between truncated spurs are hanging valleys which have not been eroded as deeply as the main valley. The river that flows through the valley after the ice age is described as a misfit stream. Characteristics of a glacial trough

© Boardworks Ltd of 31 Glaciated Landscapes.
Glaciated Landscapes Corrie Deep rounded hollows with a steep back wall. After the ice has melted a lake will be formed behind the rock lip, the lake is.
By the end of today's lessons you will be able to recognize Arêtes and explain the formation of glacial troughs and hanging valleys. Key Words; Glaciated.
In this weeks lessons we will be investigating Glaciers and how they erode, transport and deposit material. By the end of today's lesson you will be able.

Landforms Created by Glaciers Aim: To describe and explain how erosion by glaciers create Corries, Arêtes, and Pyramidal Peaks. Starter: Complete the worksheet.
Glaciation Revision for you. Get your revision techniques ready!!!! Here we go……………………
Cold Environments Distinct season below freezing with snow in winter. Can be defined by latitude and altitude ie.~ PolarArctic and subarctic PeriglacialSiberia.
Glaciation revision. Key points At all three levels (foundation, general and credit) you have to be able to recognise the main features, and be able to.
Corrie, cirque, cwm – hollow where a glacier formed Armchair shaped hollow – usually northerly aspect in UK and N. Hemisphere. Steep back wall e.g. Llyn.
LITHOSPHERE LANDSCAPE FEATURES RESULTING FROM GLACIAL AND FLUVIOGLACIAL ACTION Glacial Action by iceFluvioglacial Action by Meltwater Erosion Deposition.
River Landforms represented on O.S. Maps. V-Shaped Valley.
Snow collects in hollows, especially on the less sunny north and east facing slopes, turns to glacial ice and moves downwards under the force of gravity.
Standard Grade: Glaciation unit.. Unit aims: To find out what we mean by glaciation. To find out how landscapes have been changed by glaciation. To be.

Glacial landscapes and landforms. Landscape means the overall look or feel of a place. The photograph shows an icy environment whose steep rugged mountains.
Ice Valley Floor 3. Rocks scrape along the valley floor and erode it. 2. Glacier moves This type of erosion is called abrasion. 1. Rocks frozen into glacier.
Physical landscapes - land use C2003 Look at Reference Diagram Q1E, Reference Diagram Q1A and the OS map. Give reasons for the pattern of land use.

LITHOSPHERE GLACIATION 1 FEATURES OF GLACIAL EROSION These are the features you will need to be able to describe, explain their formation, draw a labelled.
LITHOSPHERE GLACIATION 1 Glaciation Learning Intentions Be able to understand the processes which occurred during the last ice age. Be able to describe.
Glaciation Revision Session National 4/5 Geography.
LITHOSPHERE GLACIATION 1 Glaciation 2 Selkirk High School.
GLACIATION and RIVERS REVISION Revise: how features formed How to id on a map Land use Gathering techniques.
The ‘Ice Age’ was a series of advances and retreats of the icecaps. It lasted from 1.7 million years to 10,000 years BP. Most of Britain was glaciated.
1.4Understand how moving ice acts as an agent of erosion and deposition. (Chap. 2) There are two types of glaciation. Continental Glaciation Alpine Glaciation.
LITHOSPHERE. In this unit we will look at… Glaciated Landscapes Limestone Landscapes Coastal Landscapes You will… 1.Learn about the landforms associated.
Lithosphere: Glaciated Uplands 24/08/2010 Processes of erosion recap Corrie formation.
Features of erosion and deposition associated with glaciated landscapes.
Glaciers Chapter 3 Section 4 Pages Objective: Describe the causes and types of glaciers, how they impact land features, and analyze their role.
Chapter 13: Glacial Processes, Patterns and Associated Landforms Glaciation Earth once covered with glaciers Last glaciation ended around 10,000 years.
The Physical World Revision Notes The Physical World This unit is all about Rivers, Coasts and Glaciers and how these physical entities change the land.
St.Andrews Scots School Geography Department Presents : IGCSE Geography Core Theme 2. The Natural Environment Glacial Processes.
Glacier: Any large mass of ice that moves slowly over land.
Formation of a Corrie. Small hollow on the north facing side of a hillside Water enters cracks in the rock. when temperatures fall below zero the water.

Landscapes: Glaciation unit.. Unit aims: To find out what we mean by glaciation. To find out how landscapes have been changed by glaciation. To be able.
V-Shaped valleys and Interlocking Spurs.. V-Shaped Valleys V- Shaped Valleys are found in the upper course of the river, where water flows quickly through.
Cold environments Some glacial processes and landforms.
Chapter 3 Section 4 Glaciers. Moving mass of ice and snow Form when more snow falls than melts Agent of erosion.
