Classifying landforms and landform development

1. Classifying landforms and landform development

2. Primary landforms • Large masses of rock raised by the forces beneath the earth’s surface.

3. Secondary landforms • Landforms that develop from primary landforms due to erosion.

4. Primary and secondary ex. • Surtsey – island near Iceland • Creation of it is a primary landform • The ocean waves hitting the island and creating smooth rock and beaches is a secondary landform.

6. Classifying landforms • Three different categories.

7. 1.) made of rock and slowly erodes • Plains, valleys and plateaus

8. 2.) sediment deposited by: • Water – a floodplain* or a delta* • Wind – a sand dune • ice

9. 3.) Created by tectonic activity • Greek word for “builder” • Mountains and steep, rigid valleys • Himalayas and Death Valley

10. Floodplain – level ground built by the silt of a flooded river or stream. Nile River Valley Delta- island at the mouth of a river created by sediment. Results of sediment deposits
