Volcanism, Tectonism and Orogeny.

Uplift is the process in which structural highs are created (e.g. mountains). Tectonism is largely responsible for uplift.

Most seismic activities are associated with areas of active tectonism. So earthquakes occurs principally in such areas.

Orogeny (mountain building process) is responsible for formation of high mountains. Tectonism also helps in facilitating the activities of orogeny.

The phenomenon responsible for the formation of the highest mountains is Tectonism. This is caused mostly as a result the collision movements of various lithospheric plates. The process of formation of the mountains is termed Orogeny.
