Fold mountains are
created where two or more of Earth’s tectonic plates are pushed together, often at regions known as convergent plate boundaries and continental collision zones
. The Cape Fold Mountains of South Africa, above, were created as the ancient Falklands Plateau crashed into the African plate.
What is a fold mountains explain in brief?
Fold mountains are
created where two or more of Earth’s tectonic plates are pushed together
. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. … Some of the key structures in fold mountains are nappes.
What are fold mountains give an example?
The Himalayas, The Andes and the Alps
are examples of Fold Mountain. They are the young mountains of the world and hence they have some of the highest peaks of the world.
What are fold mountains answer?
Fold mountains are
formed by the effects of folding on layers within the upper part of the Earth’s crust
. Before the development of the theory of plate tectonics and before the internal architecture of thrust belts became well understood, the term was used to describe most mountain belts, e.g. the Himalayas.
What is a fold mountain Class 6?
(1) Fold mountains:
When the land gets uplifted because of the compressional forces acting on it, a fold mountain is formned
. The Himalayas (India) and the Rockies (USA) are examples of fold mountains. … Due to this degradation, the mountains get eroded. These eroded mountains are called erosional or residual mountains.
What are the two types of fold mountains?
There are two types of fold mountains:
young fold mountains
(10 to 25 million years of age, e.g. Rockies and Himalayas) and old fold mountains (over 200 million years of age, e.g. Urals and Appalachians of the USA).
Which is the example of block mountain?
Complete answer: The
Great African Rift Valley (valley floor is graben)
, The Rhine Valley (graben) in Germany, the Vosges mountain in France, the Sierra Nevada in the USA and the Harz mountains in Germany are considered as some examples of block mountains.
What are the examples of Old fold mountains?
| Young fold mountains Old fold mountains | The Himalayas, the Andes and the Rockies mountains are some examples of young fold mountains. The Aravali Range, the Appalachian and the Ural Mountains are some examples of old fold mountains. |

Is a fold mountain answer?
Answer: Fold Mountains are
the mountains formed from the folding of the earth’s crust
. … They are formed when two tectonic plates move towards each other leading to the folding of the layers of the Earth. The up folds are called anticlines and the down folds are called synclines.
Why are fold mountains important?
Fold mountains form
along both destructive and collision plate boundaries
. … The plates push layers of accumulated sediment in the sea into folds between them. This becomes a fold mountain range. Most fold mountains continue to grow as the plates constantly move.
Is Aravalli a fold mountain?
About Aravalli
The Aravallis of Northwestern India,
one of the oldest fold mountains of the world
, now form residual mountains with an elevation of 300m. to 900m. … The Aravallis date back to millions of years when a pre-Indian sub-continent collided with the mainland Eurasian Plate.
Why are fold mountains called so?
Such stresses may be caused by weight of the overlying rocks, movements in the mantle, the expansion or contraction of some part of the earth, etc. These stresses
subject the rocks to compressive forces
, producing wrinkling or folding along the lines of weakness. Hence, these mountains are called fold mountains.
What are examples of volcanic mountains?
The most important types of volcanic mountain are composite cones or stratovolcanoes (
Vesuvius, Kilimanjaro and Mount Fuji
are examples) and shield volcanoes (such as Mauna Loa on Hawaii, a hotspot volcano). A shield volcano has a gently sloping cone due to the low viscosity of the emitted material, primarily basalt.
What are the characteristics of fold mountains for Class 6?
- Fold Mountains may be classified as young fold mountains like the Himalayas and old fold mountains like the Aravalli ranges in India.
- These mountains form irregular folds on the surface of the Earth.
- Most of the fold mountains are formed of sedimentary rocks.
What is a mountain grade 6?
Mountains. A mountain is a natural elevation of the earth, and most mountains have a small summit (top) and a broad base. Mountains are
considerably higher than the surrounding land
and some are higher than the clouds.
What do you mean by block mountain?
Block Mountains are
formed as the result of damage caused by the tensile and compressive forces caused by endogenous forces from the Earth’s interior
, also known as fault-block mountains. The Block mountains represent an upright portion of the land between two faults or on either side of a valley or canyon gap.
