31. The principle of "terrestrial whole" was advocated by which of the following experts?

Correct Answer: (b) Blache
Solution:

The principle of "terrestrial whole was advocated by 'Blache'. It means that All physical and social phenomena are closely interrelated and will coordinated on the Earth Surface. Blache is known as founding father of Human geography.

32. Which of the following statements is NOT true about Pearson's product-moment correlation coefficient 'r'?

Correct Answer: (b) 'r' is a non-parametric measure of the relationship between the two variables measured on nominal and ordinal scale.
Solution:

In statistics correlation measures the direction and extent of relationship among variables. Pearson's formulae of correlation co-efficient is a bivariate analysis and is a parametric test uses continuous interval data.

33. Which type of scattering is responsible for red sunsets?

Correct Answer: (a) Rayleigh
Solution:

Rayleigh scattering is responsible for red sunsets. Rayleigh scattering is the scattering of light by the particles present in the Atmosphere. According to the Rayleigh scattering law the amount of scattering of the light is inversely proportional to the fourth power of the wavelength.
Blue light has a lesser wavelength so it scatters more and sky seems blue. At the time of sunrise & sunset red colour of sky generate due to Rayleigh scattering. Mie scattering also called as directional scattering happens when wavelength of light is equal or near equal to size of air particle Non-selective scattering gets its name from the fact that all wavelengths are scattered about equally, resulting into appearance of white cloud.

34. The measured distance between two road intersections shown on a photograph is 10 mm on the photograph and 50 mm on the map. If the RF of the map is 1: 50,000, which one the following is the scale of the photograph.

Correct Answer: (b) 1: 250000
Solution:

R.F. of Map = 1 : 50,000
50 mm on map = 50 × 50,000 on Earth
= 2500000 m.m.
10 m.m. on Photograph = 2500000 m.m.
1 m.m. on Photograph =2500000/10
R.F. of photograph = 1: 250000

35. Which of the following curve represents the proportion of Earth's land and sea floor areas?

Correct Answer: (d) Hypsograhic curve
Solution:

The Hypsographic curve is used to demonstrate that the earth has two types of crust continental & Oceanic. The curve shows the percentage of Earth's surface that exist above any elevation by plotting relative height against relative relief. The horizontal Axis labeled % of Earth's surface while the vertical Axis shows elevation above or below sea level. * It determines what percent of Earth is above sea level. * It determines what percent of Earth's surface is below sea level.

36. Which one of the following rivers and associated projects is correctly matched in terms of location of projects in correct sequence from upper course to lower course of river?

Correct Answer: (d) Damodar River : Tenughat - Panchet Durgapur Barrage.
Solution:

Correct sequence of projects from upper course to lower course of river Damodar : Tenughat - Panchet-Durgapur Barrage.
Sequence of projects from upper course to lower course of river Chambal are Jawahar Sagar, Rana Pratap Sugar, and Gandhi Sagar.

37. According to Koppen's climatic classification of India large part of Arunachal Pradesh is represented by which of the following set of alphabets?

Correct Answer: (d) Dfc
Solution:

According to Koppen's climatic classification of India large part of Arunachal Pradesh is represented by Dfc which means shorter summer and moist cold winter climate. 'Cwg' represent climate of Gangetic plain. 'Aw' represent Tropical Savanna type climate which extends in peninsular plateau. While, ET denotes the tundra climatic condition mainly prevail in J&K and Ladakh region

38. Which of the following rivers have the largest drainage basin area?

Correct Answer: (b) Chambal
Solution:

Chambal river have the largest drainage basin area in above options. Decreasing order of drainage basins area of given rivers is Chambal (143219 km²), Narmada (98796 km²), Kaveri (81155 km²), Sutlej (56860 km²).

39. Which of the following steel plants in India is located near the coal mines?

Correct Answer: (c) Bokaro
Solution:

Bokaro steel plant is located near the coal mines and uses local coal from Chhota Nagpur plateau. Rourkela steel plant uses coal of Jharia and Talchar mines. Bhadravati Steel Plant uses wood made coal and use iron ore from Bababudan Hills. Bhilai uses coal from Bokaro & Jharia.

40. In which one of the following collision zone, plates permanently unite with on further tectonic activity?

Correct Answer: (c) Continental suture
Solution:

In continental suture plates permanently unite with no further tectonic Activity. When two convergent plate boundaries continuously moving towards each other resulting subsidence of denser plate (oceanic) beneath the lighter plate (continental) and when this subsidence occurs for a long time then they ultimately unite to from Continental Suture.
Divergent plate boundary occurs where to two tectonic plates moves away from each other. Convergent plate boundary occurs where two tectonic plates come together. Transform plate boundary occurs where two plates are sliding past each other. Subduction zones are where Earth's tectonic plates dive back into the Mantle.
