1 Desert landforms – importance of water? Erosion and deposition. Earth movements? Key Idea 1: Different forces shaping landforms.

2

3 sandstorm

4 Depositional landform.

5 Changing processes as (desert) climate changes. Landform modification occurs

6 Landforms of glacial erosion – upland Impressive features if rocks resistant

7 Pre-existing landforms? Weathering? Transport? Erosion?

8 Features of a Glacial lowland – deposition. See pre and post glacial structures and altered landforms!

9 Coastal erosion Time: headland to cave to arch to stack.

10 Longshore drift Depositional feature – a spit Importance of wind and waves

11 Glaciation meets coasts Glaciers erode below base level (out to sea) Sea level rises after ice melts

12 Post glacial uplift Isostatic recovery
