Residual mountains are remnants of old mountains which have been worn down by agents of denudation. They are usually hard resistant rocks that are let standing after the surrounding areas have been reduced by agents of denudation.
Some examples of residual mountains are: Mountain Monadnock in U.S.A., Namuli Mountains in Northern Mozambique and Hombori Mountains in Mali.
Mode of Formation of Residual Mountains
Residual mountains are formed from old fold, block or volcanic mountains by agents of denteation. They may also emerge from plateaux as hills and valleys that have been dissected by rivers. The Highlands of Scotland and the Sierras of Central Spain are Good Examples.
