Major landforms are mountain ranges, plateau and plains. Medium landforms are river valleys , karst valleys and beaches etc. Micro landforms are knick points, riffle- pools, rills etc.
These landforms are generated by different endogenic forces like diastrophic, orogenic, epeirogenic, emergence, submergence, compressional and tensional.
