Study Notes
Forces Shaping the Earth's Surface
- Internal forces: tectonic movements, volcanic activities, earthquakes
- External forces: denudational processes (weathering, mass wasting, glacial, fluvial, wind actions)
Landform and Landscape
- Landform: the shape and character of the land surface resulting from the interaction of physical and human processes
- Landform: a specific geomorphic feature on the Earth, ranging from large scale features (plains and mountain ranges) to minor features (individual gullies, faults, and valleys)
- Landscape: comprises the visible features of an area of land, including physical elements of landforms, living elements of land cover, and human elements
- Landscape: an overlay of physical and cultural elements on Earth
Landscape Types/Classification
- Arid landscapes: environments where streams and river channels are dry for most of the year
- Arid landscapes have two types of landforms:
- those where wind is the main agent of erosion/evolution
- those where water is the main agent of erosion/evolution
- Coastal landscapes: environments where water is the main geomorphic agent
- Coastal landscapes have landforms created by both water and wind
- Humid landscapes, volcanic landscapes, and glacial landscapes are also classified landscape types
Historical Development of Geomorphology
- Ancient Period: includes works of Herodotus, Aristotle, Ptolemy, and Strabo
- Dark Ages: includes the concept of the Noachian Deluge and Avicenna
- Renaissance: includes the works of Leonardo da Vinci, Buffon, Gutterhard, James Hutton, John Playfair, and Charles Lyell
- Modern Period: includes the geographical cycle of erosion, qualitative and quantitative geomorphology, and concepts from W.M.Davis, Walther Penck, Crickmay, Johnson, and Agassiz
Historical Figures
- Herodotus (485?-425 B.C.): suggested sea level changes and the formation of the Nile Delta over thousands of years
- Aristotle (384-322 B.C.): described erosion by rivers and deposition in deltas, and proposed that land can be raised from beneath the ocean
