All questions of Peninsular Plateau for UPSC CSE Exam

Dodabetta is the highest peak of Nilgiri about 2637 meter!

Deccan Plateau is located between the Western Ghats and the Eastern Ghats.

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

The area is one of the world's ten "Hottest biodiversity hotspots".

The largest physiographic division of India is the Peninsular Plateau. This plateau is a triangular landmass that covers almost half of the country. It is bounded by the Aravalli Range to the northwest, the Satpura Range to the north, the Western Ghats to the west, and the Eastern Ghats to the east. Let's examine some of the key features of this plateau.

Geology:
The Peninsular Plateau is made up of ancient rocks, some of which are over a billion years old. These rocks are primarily granites, gneisses, and schists. The plateau was formed by the drifting of the Indian tectonic plate towards the Eurasian plate, which led to the upliftment of the landmass.

Relief:
The Peninsular Plateau is a highly dissected plateau with a number of hills, valleys, and ridges. Some of the prominent hill ranges of the plateau include the Satpura, Vindhya, and Western Ghats. The plateau is also marked by a number of plateaus, such as the Deccan Plateau and the Chota Nagpur Plateau.

Drainage:
The Peninsular Plateau is drained by a number of rivers, including the Godavari, Krishna, Cauvery, and Mahanadi. These rivers flow in a generally eastward direction towards the Bay of Bengal. The plateau is also home to a number of waterfalls, including the Jog Falls and the Dudhsagar Falls.

Climate:
The climate of the Peninsular Plateau is largely influenced by its relief and proximity to the sea. The western and eastern coasts of the plateau receive heavy rainfall due to the Western Ghats and Eastern Ghats respectively. The interior regions of the plateau, however, receive less rainfall and experience a semi-arid to arid climate.

In conclusion, the Peninsular Plateau is the largest physiographic division of India. It is an ancient landmass that is highly dissected and marked by a number of hills, valleys, and plateaus. The plateau is drained by a number of rivers and is home to a diverse range of flora and fauna.

Shillong peak is the highest point of Meghalaya.

It is bounded by the Chota Nagpur plateau to the north, the Raigarh hills to the northeast, the Raipur Upland to the southeast, the Bastar plateau to the south, and the Maikala Range to the west.

Explanation:

Alpine mountain building phase

- Alpine mountain building phase is the most recent phase of mountain building that occurred during the Cenozoic era, which began about 65 million years ago.
- It is also known as the Neogene orogeny.
- The Alps, the Himalayas, the Andes, the Rockies, and other mountain ranges around the world were formed during this phase.

Himalayan mountains

- The Himalayan mountain range is a part of the Alpine mountain building phase.
- The Himalayas were formed by the collision between the Indian Plate and the Eurasian Plate.
- The Himalayas are the youngest and highest mountains in the world.

Ural Mountains

- The Ural Mountains are a mountain range that runs north to south through western Russia.
- The Ural Mountains were formed during the Uralian orogeny, which occurred during the Paleozoic era, about 300 to 250 million years ago.
- The Uralian orogeny is an older phase of mountain building that occurred before the Alpine orogeny.

Answer:

- Statement 1 is correct. The Himalayan mountains belong to the Alpine mountain building phase.
- Statement 2 is incorrect. The Ural Mountains were not formed during the Alpine orogeny, but during the Uralian orogeny. Therefore, the correct answer is option 'A' - 1 only.

Bundelkhand is divided between the states of Uttar Pradesh and Madhya Pradesh, with the larger portion lying in the latter.

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.
