- 2. Geomorphology • Geomorphology is the study of landforms and the processes that shape them, past and present • It is the study of evolution and formation of landscapes or landforms
- 3. Endogenic processes in geomorphology • The endogenic process is an internal geomorphic process. The energy emanating from within the earth is the main force behind endogenic geomorphic processes. This energy is mostly generated by radioactivity, rotational and tidal friction and primordial heat from the origin of the earth.
- 4. Exogenic Processes • The exogenic processes obtain their energy from the gradients generated by tectonic factors, processes, their corresponding driving forces and atmosphere determined by the energy from the sun. • Precipitation and temperature are the two significant climatic components that regulate different processes. • Whole exogenic geomorphic processes are covered under a common term, denudation which means to uncover. • Weathering, transportation, and erosion are comprised of denudation.
- 5. Geological action by fluvial processes • Such a fluvial process plays an essential and very significant role in the weathering of the land surfaces and the process causes the transportation which is known as fluvial transportation of the rock debris from higher to lower levels. • the physical interaction of flowing water and the natural channels of rivers and streams.
- 6. Types of Fluvial Processes • River form • Landform • Aeolian process • Glacial Process • Coastal Geomorphology
- 7. General principles of stratigraphy • The principles on which the stratigraphic studies are based include order of superposition, original horizontality, lateral continuity, cross- cutting relationships, inclusions, unconformities, fossil succession, uniformitarianism and catastrophism.
- 8. Geological time scale w.r.t. Indian geological time scale • India has its own geological eras and periods that correspond to the standard geological eras of Pre- Cambrian (over 570 million years old), Paleozoic (245-570 million years old), Mesozoic (65-245 million years old) and Cenozoic (65 million years old to the present).
