What is Geomorphology? Simply, geo means earth, morpho means form, logy means description It is a study of landforms (physical features on earth surface) It deals with their formation and changes occurring in the landforms landform formation To study about the nature and mechanism of different forces which - It deals with types , nature , process and forces responsible for evolve the landforms Two forces-Endogenetic forces and exogenetic forces
ENDOGENETIC FORCES Forces coming from within the earth are called endogenetic forces Act inside the earth's crust Objective of these forces is to create various relief features on the earth's surface Relief means with respect to MSL, difference of heights of different places on earth surface.
Endogenetic for Endogenetic forces Epiorogenetic forces Diastrophic forces Orogenetic forces Endogenetic forces Volcanic eruption and earthquakes Sudden forces

These forces cause upliftment and subsidence of continental massest order landforms). Movements are vertical Orogenetic forces means mountain formation. Movements are horizontal. E.g. Tensile compressive and shear foces (2nd order landforms)
