A residual mountain or mountains of denudation is a type of landform that gets made over the years following the erosion of already elevated lands. The shape of the earth's surface can be altered by forces both within and outside the earth. Geomorphic powers have also been discussed in previous Geography notes. Many different landforms can be created by endogenic and exogenic forces. A landform is a normal characteristic of the Earth's solid surface.

Residual Mountains or Mountains of denudation

Residual Mountains Examples - Mountains, Plateaus, and Plains are examples.

Residual landform, also known as a relict mountain, is a type of landform that was formed as the remains of an ancient landscape, surviving burial or destruction to become part of the current landscape. Modified climatic conditions are often the cause of residual landforms, but they may also be caused by volcanism or crustal uplift and down warping. Extinct volcanic cones, inactive stone rivers from climates on the edge of glaciers, disconnected and abandoned drainage system bits, abandoned strandlines from more humid climates, fixed sand dunes from drier climates, coastal terraces from high sea levels, and plunging sea cliffs from lower sea levels are examples of residual landforms. The percentage of residual landforms in a given landscape and the value given to relic landforms by various geomorphologists can differ dramatically.

Till is a term used in geology to describe unsorted material accumulated directly by glacial ice with no stratification. Till is also known as boulder clay because it is made up of clay, intermediate-sized boulders, or a combination of the two. Since the rock fragments are deposited from the ice and have had little water transport, they are normally angular and sharp rather than rounded. Grinding may have faceted and striated the pebbles and boulders once embedded in the glacier. The fragments in some till deposits are poorly organized: large numbers of stones may lie with their long axes parallel to the glacier's flow path. Other glacial indicators do not provide as reliable information about flow direction as this method. There are two forms of till: basal and ablation, which are difficult to discern by appearance. Basal till was carried in the glacier's base and was usually laid down underneath it. Ablation till was placed on or near the glacier's surface and released as the glacier melted.


Residual Mountains and Their Examples

There are several different types of landforms on this planet. Mountain refers to any natural elevation of the earth's surface.


Residual Mountain

Residual mountains are those that have been eroded by erosion agents such as winds, rain, frost, and flowing water, leaving only the hard rocks behind. The residual mountains are the hard rocks that are left behind. These mountains are made up of existing mountains such as folds, blocks, and volcanoes. Wind, water, glaciers, waves, and other agents of denudation wear away at high mountains. Residual mountain refers to the remaining portion of these mountains.

The remaining mountains include the Sierras of central Spain and the Mesas of the United States. The Aravalli Mountain and the Parasnath Mountain in Bihar are examples of this kind in India. The Namuli Mountains in Mozambique and the Hanbori Mountains in Mali are two other examples.


Plateaux

A plateau is a flat, elevated region of land above sea level. The word 'Plateau' comes from the French and means 'table ground.' Plateaux are highlands that resemble plains due to their flat summits.

Plateaux combines the benefits of mountains and plains, making them ideal for agriculture and animal husbandry.


Groups of Plateaux

Residual Plateau - 

On at least one foot, a plateau is a high, elevated landform that rises sharply above the surrounding area.

Plateaux may be categorized according to their formation or location.

The Intermontane Plateau - When a plateau is surrounded on all sides by mountains, it is considered an intermontane plateau. The Tibetan and Bolivian plateaus are also examples of intermountain plateaus.

ii. The Piedmont Plateau - A piedmont plateau is bounded on one side by a mountain. The Patagonian plateau in Argentina and the Piedmont plateau in America are two examples.

A continental plateau is surrounded by seas or plains. These plateaus are enormous. Western Australia's plateau and Africa are two examples.


Summary of Residual Mountains

  • Mountains with Residuals Residual mountains are the remnants of previously existing mountains that have been lowered or diminished by agents of denudation such as running water, ice, and wind.

  • After the upper part of the mountains has been lowered, some rough and very resistant sections of the current mountains have remained.

  • The remaining portion is known as the Residual Mountains, which are also known as Denudation Mountains.

  • This form includes the Aravalli Mountain and the Parasnath Mountain in Bihar.

FAQ (Frequently Asked Questions)

1. What are Residual Mountains? Give Some Examples of Such Mountains.

Ans - Mountains that have been eroded by erosion agents such as winds, rain, snow, and running water are known as residual mountains. Residual mountains are the heavy rocks that are left behind. These mountains are made up of existing mountains such as folds, blocks, and volcanoes. Wind, water, glaciers, waves, and other agents of denudation wear away at high mountains. Residual mountain refers to the remaining portion of these mountains.


The remaining mountains include the Sierras of central Spain and the Mesas of the United States. The Aravalli Mountain and the Parasnath Mountain in Bihar are examples of this kind in India. The Namuli Mountains in Mozambique and the Hanbori Mountains in Mali are two other examples.

2. Explain Residual Landform in Detail.

Ans - Residual landform, also known as relict landform, is a type of landform that was formed as the remains of an ancient landscape, surviving burial or destruction to become part of the current landscape. Modified climatic conditions are often the cause of residual landforms, but they may also be caused by volcanism or crustal uplift and down warping. Extinct volcanic cones, inactive stone rivers from climates on the edge of glaciers, disconnected and abandoned drainage system bits, abandoned strandlines from more humid climates, fixed sand dunes from drier climates, coastal terraces from high sea levels, and plunging sea cliffs from lower sea levels are examples of residual landforms. The percentage of residual landforms in a given landscape and the value given to relict landforms by various geomorphologists can differ dramatically.
