1. Fluvio-Glacial Landforms

2. Fluvio-glacial landforms are landforms molded by glacial meltwater. There are 2 main fluvio-glacial features; 1)Outwash Plains 2)Eskers

3. Outwash Plains; This is made up of glacial material picked up by meltwater and deposited beyond where the ice reached Outwash can also be deposited on top of boulder clay as the ice melts The outwash plain is sorted and rounded because it has been deposited by water The coarsest deposits (sands and gravel) are deposited first and found nearest the ice; the finer deposits (clay, silt) are deposited last and found furthest from the ice.

5. Eskers; These are long, narrow, sinuous ridges often several miles long. They are made of stratified glacial material (i.e. in layers) especially sand and gravel picked up and deposited by water They are formed by rivers inside or under the melting ice being under great pressure and so able to transport much sediment The sediment is deposited along the course of the sub-glacial river so that, when the ice melts and the meltwater drains away, the raised bed of the subglacial river is left as an esker Eskers are layered because, at different times, the meltwater river would have differing amounts of energy and so deposits varying amounts of material of different sizes.

7. Task 1: Using your lithosphere book answer the following questions. 1)What 4 types of material are transported by glaciers 2)Where are each carried on the glacier? 3)Explain the formation of a terminal moraine 4)What is an erratic? 5) How is an outwash plain formed?

8. Homework! Due in Friday 31 st August Answer the 2000 past paper question on glaciation This is worth 6 marks. You are asked to explain the processes involved in the formation of 2 landforms. 3 marks for a feature of glacial erosion 3 marks for a feature of glacial deposition Therefore, you should be mentioning 6 key points for each. Write this in your homework diary!!!
