NTA UGC NET/JRF Exam, June, 2020 Geography

Total Questions: 100

1. Which one of the following is not a nonrenewable resources?

Correct Answer: (d) Solar energy
Solution:

Solar energy comes from the sun as radiant energy in the form of both heat and light. The sun is infinite; it is calculated that it will be at least 5 billion years before it begins to show any sign of deterioration. Therefore, it is said that solar energy is renewable, not non-renewable. While, Non-renewable energy is a source of energy that will eventually run out. Most sources of non-renewable energy are fossil fuels, such as coal, gas, and oil. Not a non - renewable' means 'Renewable Energy Source' so According to 'UN' Renewable Energy is Energy derived from natural sources that are replenished at higher rate than they are consumed.

2. Who is recognized as the founder of Scientific Marine Meteorology

Correct Answer: (b) M.F. Maury
Solution:

Matthew Fontaine Maury is recognized as the founder of Scientific Marine Meteorology, was an American astronomer, historian, oceanographer, meteorologist, cartographer. He was nicknamed "Pathfinder of the Seas" and "Father of Modern Oceanography and Naval Meteorology" and later, "Scientist of the Seas" for his extensive works in his books,
Marine meteorology is a subfield of meteorology that deals with overarching weather and climate systems, while more specifically honing into the associated oceanographic conditions in marine environments and the interactions between the ocean and atmosphere.

3. Match List I with List II:

Correct Answer: (d)
Solution:

4. Who among the following defined Geography as a Chronological Science?

Correct Answer: (b) Hettner. J
Solution:

German geographer Alfred Hettner defined geography as a chronological science. He was of the view that geography should be studied as a chronological science, which studies diverse phenomena existing together in regions of the earth's space. The term chorology composed of two, words 'choros' means 'place' and logy means 'study of, The term chorology is also known as 'Areal differentiation and its study is vague since the 'Strabo' time.

5. Match List I with List II:

List I- (Measurement Methods)
(A) Rank coefficient Method
(B) Crop yield and concentration indices
(C) Carrying capacity of land
(D) Index of Productivity
Last II - (Devised by)
(I) Jasbir Singh
(II) Dudley stamp
(III) Kendall
(IV) M. Shafi
Choose the correct answer from the options given below:

Correct Answer: (a)
Solution:

6. Ria is an example of:

Correct Answer: (a)Submerged upland shore
Solution:

Ria Coast is a submergence coast. This type of coast are mainly found in Atlantic region of north-west France, north-west Spain, south-west Ireland etc. Ria coast are developed when coastal mountains run at right angles to the sea and a rise in the sea level submerges or drowns the lower parts of the valleys. Portuguese word 'Ria' means river. At the same time, the Spanish word 'Ria' means coast.

7. Given below are two statements: One is labeled as Assertion (A) and the other is labeled as Reason (R):

Assertion (A): Along with water vapour carbon dioxide is largely responsible for the green house effect of the atmosphere.
Reasons: Carbon dioxide is not an important heat absorber.
In the light of the above Statements, choose the most appropriate answer from the options given below:

Correct Answer: (c) (A) In true but (R) is false
Solution:

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2020, CO2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities. Carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and certain other gases absorb IR radiation from the terrestrial radiation of Earth's surface and re-emit it in all directions. These gases act like the glass in a greenhouse that permits the entrance sunlight but blocks its exit causes to increase the temperature of the planet. Hence (A) is true but (R) is false.

8. Which one of the following percentage of solar radiation reflected back and scattered to space?

Correct Answer: (c) 30%
Solution:

The Sun has been radiating a tremendous quantity of power at the present rate for almost 5 billion years and could keep radiating at that rate for approximately 5 billion years more.
The calculation of total amount of sunlight reaches to earth surface and reflected back into space is called as Earth's Heat Budget. Of all the solar radiation reaching Earth, 30% is reflected back to space and 70% is absorbed by Earth i.e. (47%) and atmosphere (23%).

9. Given below are two statements:

Statement I: In any system of constant mass, energy is neither created nor destroyed. Statement II: The energy flow in the ecosystem is NOT unidirectional.
In the light of the above Statements, choose the most appropriate answer from the options given below:

Correct Answer: (c) Statement I in correct but Statement II is incorrect
Solution:

The first law of thermodynamics, that states that energy can neither be created nor destroyed, it can only change from one form to another. The energy flow in the ecosystem is clearly unidirectional i.e. from organisms of lower trophic level to organisms of higher trophic level. Hence Statement I is correct but Statement II is incorrect

10. Given below are two statement: One is labeled as Assertion (A) and the other is labeled as Reason (R):

Assertion (A): Laterite soil is formed under the conditions of high temperature and high rainfall with alternate wet and dry periods.
Reasons(R): The laterite soils swell greatly and become sticky when wet in rainy season and also known as ‘Self ploughed’.
In the light of the above Statements, choose the most appropriate answer from the options given below:

Correct Answer: (c) (A) is correct but (R) is not correct
Solution:

Laterite soils are mostly the end products of weathering. They are formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods. Significantly, Heavy rainfall promotes leaching (nutrients get washed away by water) of soil whereby lime and silica are leached away and a soil rich in oxides of iron and Aluminium compounds is left behind.
They are very poor in lime, magnesia, potash, and nitrogen. Sometimes, the phosphate content may be high in the form of iron phosphate. In wetter places, there may be a higher content of humus while Black soil is known as self ploughing soil Which becomes wet and swells during rainy season. Therefore, (A) is correct but (R) is not correct
