Deepak Chauhan answered
  • There are three types of mountains: Fold Mountains, Block Mountains and the Volcanic Mountains.
  • The Himalayan Mountains and the Alps are young fold mountains with rugged relief and high conical peaks.
  • The Aravalli range in India is one of the oldest fold mountain systems in the world. The range has considerably worn down due to the processes of erosion.
  • The Appalachians in North America and the Ural mountains in Russia have rounded features and low elevation. They are very old fold mountains

Which of the following are true with respect to fold mountains?
1. Their tops are often buried beneath snow and ice.
2. They are caused by the contraction of the earth's crust.
3. They form rugged peaks. 
4. Fold mountains are mostly found along continental margins facing oceans
  • a)
    1 and 3 only
  • b)
    1 and 2
  • c)
    2, 3 and 4
  • d)
    1, 3 and 4
Correct answer is option 'D'. Can you explain this answer?

Maitri Desai answered
- Option 1: True. The high altitudes of fold mountains often lead to snow and ice accumulation on their peaks, such as the Himalayas and the Alps.
- Option 2: False. Fold mountains are formed by the collision of tectonic plates, not the contraction of the Earth's crust.
- Option 3: True. Fold mountains have rugged peaks due to tectonic activity and erosion.
- Option 4: True. Fold mountains are often located along continental margins where tectonic plates converge, like the Andes and Rockies.

The correct answer is D: 1, 3, and 4.

Which river borders Meghalaya-Mikir Uplands in the east?

This river receives almost all the western and southern drainages of Nagaland. Its main tributaries are river Dzuza and Diphu.

In humid highlands, several dissected plateaus like the Scottish Highlands are found. Which of the forces are responsible for the formation of such dissected plateaus?
1. Stream action
2. Cuts done due to glaciation
3. Abrasion by wind
Which of the above statement(s) is/are correct?
  • a)
    1 and 2 only
  • b)
    2 and 3 only

    1 and 3 only
  • d)

Correct answer is option 'D'. Can you explain this answer?

Ayush Kulkarni answered
  • A dissected plateau is an area that has been severely eroded and divided into several smaller pieces.
  • The natural agents, such as the Sun, the rain, the wind, the running water and the Glacier, wear away the soft rocks of the upland areas.
  • The resistant rock masses are left there standing on the ground above the surroundings.
  • The sometimes from the almost level surface, cut by rivers and streams. These upland areas together form a dissected plateau.

Why a very large thickness of sedimentary rocks is found in the Fold Mountains?
  • a)
    Due to the folding of sediments.
  • b)
    Due to the folding of plains into mountains
  • c)
    Due to accumulation of sediments in a geosyncline
  • d)
    Sediments have been deposited in the valley for millions of years
Correct answer is option 'C'. Can you explain this answer?

Jaideep Singh answered
  • Formation of Fold Mountains: Rivers deposit huge quantities of sediments in depressions called geosynclines. Over millions of years, the sediments arc compressed into sedimentary rocks such as sandstone and limestone. The plates move together forcing the sedimentary rocks upwards into a series of folds by the movement of tectonic plates. This causes the thickness of the rocks in fold mountains.

Which is the largest physiographic division of India?
  • a)
    The Northern Mountains
  • b)
    The Great Plains
  • c)
    The Peninsular Plateau

  • c)
    It depends on its shape
  • d)
    It does not depend on its temperature
Correct answer is option 'B'. Can you explain this answer?

Abhiram Saha answered
Mass of a body
The correct statement about the mass of a body is that it is the same everywhere. This concept is a fundamental principle in physics known as the conservation of mass. Here's why:

Uniformity of mass
- Mass is an intrinsic property of matter that remains constant regardless of its location. This means that the mass of an object on Earth is the same as its mass on the Moon or any other location in the universe.
- This uniformity of mass is crucial in many scientific calculations and experiments, as it allows for consistent measurements and comparisons between different objects.

Definition of mass
- Mass is a measure of the amount of matter in an object. It is often confused with weight, but mass is independent of gravity and weight changes depending on the gravitational force acting on an object.
- The SI unit of mass is the kilogram (kg), and it is a scalar quantity, meaning it only has magnitude and no direction.

Conclusion
- In conclusion, the mass of a body is the same everywhere, as it is a fundamental property of matter that does not change based on its location, shape, or temperature. This principle plays a crucial role in various scientific disciplines and is a cornerstone of our understanding of the physical world.
