Old fold and young fold mountains
Show SolutionHide Solution↓
| Sl. No. | Old fold mountains | Young fold mountains |
|---|---|---|
| 1. | They are lower in height. | They are very high mountains. |
| 2. | They have rounded peaks and gentle slopes. | They have pointed peaks and steep slopes. |
| 3. | Examples: The Appalachians in North America, the Urals in Europe | Examples: The Himalayas in India, the Rockies in North America. |
2
Rift Valley and block mountains
Show SolutionHide Solution↓
| Sl. No. | Rift Valley | Block Mountains |
|---|---|---|
| 1. | Rift Valley is a lowland region that forms where earth's tectonic plates move apart or rift. | Block Mountains are formed as a result of faulting. |
| 2. | Rift Valley is bordered by faults zones and separated by land masses. | Block Mountains have steep sides, flat top and are enclosed by faults. |
| 3. | Examples: Vosges in France, Vindhyas in India | Examples: Rhine Valley of River Rhine, Rift Valley of river Narmada. |
3
Erosional plains and depositional plains
| Sl. No. | Erosional Plains | Depositional Plains |
|---|---|---|
| 1. | Erosional Plains are formed as a result of erosion by running water, wind and rivers. | Depositional Plains are formed as a result of deposition of sediments brought by rivers. |
| 2. | Example: Plains around Aravalli region | Example: Indo-Gangetic plains in India. |

How are fold mountains formed? Give two examples of fold mountains?
Show SolutionHide Solution↓
The fold mountains are formed when earth's movement throws massive folds or ridges which form the mountains. These movements of earth are primarily horizontal movement and cause 'wrinkles' or 'folds'. The upraised parts of the folds are called anticlines and downward folds are called synclines. Two example of fold mountains are:
- The Himalayas in India
- Rockies in North America
2
State two characteristics of block mountains.
Show SolutionHide Solution↓
Two characteristics of block mountains are:
- Block mountains are steep sided and flat topped.
- Block mountains are characterised by massiveness, steep slopes and comparatively smooth topography.
3
How are rift valleys formed? Give one example of rift valley.
Show SolutionHide Solution↓
A Rift Valley is formed when earth's tectonic plates move apart or rift. It is a linear depression or trough created by the sinking of the intermediate crustal rocks between two or more parallel faults. Rhine Valley is one of the examples of Rift Valley.
4
Compare life in the mountains and in the plains.
Show SolutionHide Solution↓
| Sl. No. | Life in the mountains | Life in the plains |
|---|---|---|
| 1. | People face the problem of conveyance as these regions are not well connected by roadways, railways and airways. | Conveyance is easy for people as levelled land makes it easy to construct roads and railway lines. |
| 2. | People have to face environmental and economical difficulties. There is sparse population | The fertile land promotes agriculture and irrigation is also cheap. It supports dense population. |
| 3. | They are centres of mining as they are rich in deposits of minerals. | Agriculture is the most important occupation. |
5
What type of mountain is Mt. Kilimanjaro?
Show SolutionHide Solution↓
Mt. Kilimanjaro is a Volcanic mountain.
6
Define structural plains.
Show SolutionHide Solution↓
The plains that are formed as a result of emergence of sea bottom near coast are known as structural plains.
1
Young fold mountains have high peaks
Show SolutionHide Solution↓
Young fold mountains have high and pointed peaks because they are younger and have not been much eroded by wind or water. On the contrary, old fold mountains have been subjected to the forces of denudation (such as weather, rivers, glaciers) for a longer geological period. Due to this prolonged erosion, they are lower in height and have round peaks.
2
Tibetan plateau is surrounded by mountains.
Show SolutionHide Solution↓
Tibetan plateau is an example of Intermontane plateau as it is surrounded by the Himalayas and the Kunlun mountains.
3
Rift valley have steep sides
Show SolutionHide Solution↓
Rift valley have steep sides because they are formed as a linear depression or trough by the sinking of the intermediate crustal rocks between two or more parallel faults. Sudden rifting of tectonic plates leads to steep sides of Rift valley.
