Landforms
The document defines landforms as natural features on the Earth's surface created by geological processes. It describes how landforms are formed through processes like magma solidification, weathering, erosion, deposition, and tectonic activity. The document then lists and provides examples of major landform types including mountains, hills, plateaus, plains, bays, canyons, and straits.

Editor's Notes
- #4 When you look at the earth’s surface .. What can you say about it..?? The earth’s surface is not flat. When we look at it we are looking at the different landforms shaped by all of earth’s processes
- #6 A Landform is a physical, natural or manmade structure which is situated on earth's surface, whereas a Landscape is the combined natural and cultural features of an area on the earth's surface.
- #8 Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.
