Orogeny refers to forces and events leading to a large structural deformation of the Earth's lithosphere ( crust and uppermost mantle) due to the interaction between tectonic plates. Orogens or orogenic belts develop when a continental plate is crumpled and is pushed upwards to form mountain ranges, and involve a great range of geological processes collectively called orogenesis.
The word "orogeny" comes from the Greek (ὄρος oros for "mountain" and γένεσις genesis for "creation" or "origin"),. Orogeny is the primary mechanism by which mountains are built on continents. The term was employed by the American geologist G.K. Gilbert in 1890 to describe the process of mountain building, distinguishing it from epeirogeny.
