Question 51. When Granite rocks get metamorphosed, they form
  1.    Marble
  2.    Quartzite
  3.    Slate
  4.    Gneiss
 Discuss Question
Answer: Option D. -> Gneiss
Answer: (d)
Gneiss is a high-grade metamorphic rock formed by the metamorphosis of granite which is a sedimentary rock. Gneiss is typically associated with major mountain building episodes.
It is often foliated (composed of layers of sheet-like planar structures), characterized by alternating darker and lighter coloured bands, called “gneissic banding”.
Question 52. Which of the following is an example of Plutonic Igneous Rock?
  1.    Slate
  2.    Basalt
  3.    Dolomite
  4.    Granite
 Discuss Question
Answer: Option D. -> Granite
Answer: (d)When magma solidifies under the earth’s surface, it forms plutonic rock bodies or plutons. The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite.
Question 53. The disconnected lines drawn on a map for showing slope
  1.    Form lines
  2.    Bench marks
  3.    Hachure
  4.    Contours
 Discuss Question
Answer: Option C. -> Hachure
Answer: (c)
Hachures are short disconnected lines drawn on the map to depict the slope of the ground surface. They are drawn in rows; each row being disconnected from the other.
They are short and closely spaced for steep slopes and relatively long and widely spaced for gentler slopes. Hachures are not drawn for levelled areas, such as a flat valley or a plateau top.
Question 54. What is the correct sequence from the smallest to the largest grain of the following types of clastic rocks?
  1.    Conglomerate, sandstone, shale, siltstone
  2.    Shale, sandstone, conglomerate, siltstone
  3.    Sandstone, siltstone, conglomerate, shale
  4.    Shale, siltstone, sandstone, conglomerate
 Discuss Question
Answer: Option D. -> Shale, siltstone, sandstone, conglomerate
Answer: (d)
Question 55. Where are day and night equal throughout year?
  1.    Equator
  2.    North Pole
  3.    Nowhere
  4.    South Pole
 Discuss Question
Answer: Option A. -> Equator
Answer: (a)
Question 56. Sandstone is flasky rock, because
  1.    It is formed under water
  2.    It is formed in desert
  3.    It is formed on the mountain
  4.    It is formed due to heat
 Discuss Question
Answer: Option A. -> It is formed under water
Answer: (a)
Question 57. The Equator does not pass through which of the following countries?
  1.    Indonesia
  2.    Kenya
  3.    Brazil
  4.    Mexico
 Discuss Question
Answer: Option D. -> Mexico
Answer: (d)
The equator passes through 13 countries:
Ecuador,
Colombia,
Brazil,
Sao Tome & Principe,
Gabon,
Republic of the Congo,
Democratic Republic of the Congo,
Uganda,
Kenya,
Somalia,
Maldives,
Indonesia and
Kiribati.
Question 58. In which one of the following countries are Pampas Grasslands located?
  1.    Argentina
  2.    Paraguay
  3.    Uruguay
  4.    Bolivia
 Discuss Question
Answer: Option A. -> Argentina
Answer: (a)
Question 59. Why is the South Pole colder than the North Pole?
  1.    Strong winds
  2.    High altitude
  3.    Away from the sun
  4.    More rainfall
 Discuss Question
Answer: Option B. -> High altitude
Answer: (b)
Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. What makes the South Pole so much colder than the North Pole is that it sits on top of a very thick ice sheet, which itself sits on a continent.
The surface of the ice sheet at the South Pole is more than 9,000 feet in elevation—more than a mile and a half above sea level. This elevation makes the South Pole much colder than the North Pole, which sits in the middle of the Arctic Ocean (National Geographic).
Question 60. Which one of the following is not a metamorphic rock?
  1.    Quartzite
  2.    Geneiss
  3.    Schist
  4.    Conglomerate
 Discuss Question
Answer: Option D. -> Conglomerate
Answer: (d)
The conglomerate is not a metamorphic rock. The conglomerate is a rock consisting of individual clasts within a finer-grained matrix that have become cemented together.
Conglomerates are sedimentary rocks consisting of rounded fragments and are thus differentiated from breccias, which consist of angular clasts.
