📆 October 24, 2024

Total Questions: 7

1. The area which is the 'storehouse of minerals' in South America is: [R.A.S./R.T.S.(Pre) 2010]

Correct Answer: (c) Patagonia Plateau
Solution:Patagonia Plateau is called as the storehouse of minerals, in South America. Patagonia refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. It is a Piedmont plateau (Arid Landforms) lying in southern part of Argentina. It is a rain shadow desert plateau. It is an important region for sheep rearing.

2. Which is known as 'Roof of the World'? [44th B.P.S.C. (Pre) 2000]

Correct Answer: (c) Pamir
Solution:The Pamir Plateau or the "Pamir" is called the roof of the world because of its high altitude. The southern border of Central Asia is determined by Pamir Plateau. It is a convergence of many mountains. The Pamir Plateau is situated in the heart of Central Asia, primarily within Tajikistan, but also extending into parts of Afghanistan, China, and Kyrgyzstan. The Pamir Plateau is known as the "Roof of the World" due to its exceptionally high altitude, with an average elevation of around 4,000 meters (13,123 feet). The Pamir Plateau is a major mountain convergence zone, where several major mountain ranges meet, forming what is known as the Pamir Knot. The Pamir Plateau was formed by the collision of the Indian and Eurasian tectonic plates, which led to the uplift of the Himalayas and other mountain ranges. The Pamir Plateau has a harsh, arid, and continental climate, with long, cold winters and short, cool summers. Despite the harsh climate, the Pamir Plateau supports a variety of alpine desert and tundra vegetation. The rugged terrain and extreme altitude make the Pamir Plateau one of the most inaccessible regions on Earth.

3. Telegraphic Plateau is a part of : [U.P.P.C.S. (Pre) 2019]

Correct Answer: (a) North Atlantic Ridge
Solution:Telegraphic Plateau is a part of North Atlantic Ridge. It is between New Found land to Ireland. The "Telegraph Plateau" name originated from the mid-19th century, when it was believed to be a relatively flat and shallow region in the North Atlantic, which was important for laying telegraph cables. It consists of oceanic crust and a part of the Reykjanes Ridge, which is the northern branch of the Mid-Atlantic Ridge, where the plateau crosses from the Eurasian plate to the North American plate.

4. Out of the following which combination is incorrect? [M.P. P.C.S. (Pre) 2019]

Correct Answer: (a) Telegraph Plateau - Indian Ocean
Solution:Telegraph Platean lies in the Atlantic ocean.

The correct matching is as follows:

List-IList-II
Telegraph PlateauAtlantic Ocean
Cocoa RidgePacific Ocean
Walvis RidgeAtlantic Ocean
Agulhas BasinIndian Ocean

It is important to mention here that the telegraphic plateau is considered a hydrographic myth.

5. The average elevation of Tibetan Plateau above sea level is [U.P.U.D.A./L.D.A. (Pre) 2013, I.A.S. (Pre) 1994]

Correct Answer: (d) 5 Km
Solution:Tibetan Plateau is also known as Qinghai-Tibetan Plateau. Its total area is about 2.5 million square kilometers and an average elevation is more than 4500 meter. Thus, the closest answer is option (d). The formation of the Tibetan Plateau is tied to Himalayan orogeny. The northward-moving Indian plate collided with the Eurasian plate. The movement resulted in strong uplift of the then southern edge of the Asian continental mass, which led to the uplift of the Tibetan plateau. The rise occurred during the first 10 million years after the tectonic collision between Asia and India began 45 million years ago. Still growing, the Tibetan Plateau's spread has slowed to an annual growth rate of 7 cm wider per year.

6. A city situated on a Plateau is- [R.A.S./R.T.S. (Pre) 1991]

Correct Answer: (b) Madrid
Solution:

Madrid, the capital of European country Spain is situated on Meseta Plateau in the Iberian Peninsula. The elevation of this plateau is between 610-760 meter. Elevation of other cities given in the options is as follows:

LocationElevation (above sea level)
Bucharest (At the Bank of Dambovita River)55.8 metre
Jamnagar (Gujarat)20 metre
Singapore (South East Asia)15 metre

7. Which one amongst the following is the largest plateau? [U.P.P.C.S. (Pre) 2017]

Correct Answer: (c) Colorado
Solution:
NameArea (sq. mile)
Coconino5000 sq. mile
Aquarius900 sq. mile
Colorado150580 sq. mile
Columbia105633 sq. mile

So, among the given options colorado is the largest plateau whereas the largest plateau of the world is Tibetan Plateau.
