Question 261. Quartzite is metamorphosed from
  1.    Limestone
  2.    Obsidian
  3.    Sandstone
  4.    Shale
 Discuss Question
Answer: Option C. -> Sandstone
:
C
Ans. (c)
Explanation
Quartzite is metamorphosed from Sandstone while Shale is from Slate.
Question 262. Consider the following climatic and geographical phenomena :
1. Condensation
2. High temperature and humidity
3. Orography
4. Vertical wind
Thunder Cloud development is due to which of these phenomena?
  1.    1 and 2
  2.    2, 3 and 4
  3.    1, 3 and 4
  4.    1, 2, 3 and 4
 Discuss Question
Answer: Option D. -> 1, 2, 3 and 4
:
D
Ans. (d)
Explanation
The thunder cloud develops by all the above climatic and geographical phenomena.
High temperature and humidity causes the wind to rise vertically up, due to Orography or pressure of mountains.
These winds get condensated and form Cumulonimbus clouds or thunder clouds.
Question 263. Assertion (A): During the Neap Tides, the high tide is lower and the low tide is higher than usual.
Reason (R): The Neap Tide, unlike the Spring Tide, occurs on the New Moon instead of on the Full Moon.
  1.    Both A and R are true and R is the correct explanation of A
  2.    Both A and R are true but R is NOT the correct explanation of A
  3.    A is true but R is false
  4.    A Js false but R is true
 Discuss Question
Answer: Option C. -> A is true but R is false
:
C
Ans. (c)
Explanation
The reason for lower high tide and higher low tide is - as it occurs on the new moon. So the gravitational pull of the moon is less than the full moon.
Question 264. Identify the correct order of the processes of soil-erosion from the following :
  1.    Splash erosion, Sheet erosion, Rill erosion, Gully erosion
  2.    Sheet erosion, Splash erosion, Gully erosion, Rill erosion
  3.    Rill erosion, Gully erosion, Sheet erosion, Splash erosion
  4.    Gully erosion, Rill erosion, Sheet erosion, Splash erosion
 Discuss Question
Answer: Option A. -> Splash erosion, Sheet erosion, Rill erosion, Gully erosion
:
A
Ans. (a)
Explanation
The correct order of soil erosion process is Splash-Sheet-Rill - Gully and Ravine erosion.
Question 265. Consider the following statements :
1. In equatorial regions, the year is divided into four main seasons.
2. In Mediterranean region, summer receives more rain.
3. In China type climate, rainfall occurs throughout the year.
4. Tropical highlands exhibit vertical zonation of different climates.
Which of these statements are correct?
  1.    1, 2, 3 and 4
  2.    1, 2 and 3
  3.    1, 2 and 4
  4.    3 and 4
 Discuss Question
Answer: Option D. -> 3 and 4
:
D
Ans. (d)
Explanation
Only 3, 4 are correct. Because in equatorial regions there is no clear distinction of main seasons. In Mediterranean area there is rainfall during the winter but not in summer.
Question 266. Frozen dew is known as-
  1.    smog
  2.    frost
  3.    sleet
  4.    mist
 Discuss Question
Answer: Option B. -> frost
:
B
Ans. (b)
Question 267. Volcanic activity leads to the formation of-
  1.    Coastal terraces
  2.    River valleys
  3.    Crater lakes
  4.    Limestone caves
 Discuss Question
Answer: Option C. -> Crater lakes
:
C
Ans. (C)
Question 268. When humidity increases beyond the dew point, it results in:
  1.    Winds
  2.    Mirage
  3.    Condensation
  4.    Evaporation
 Discuss Question
Answer: Option C. -> Condensation
:
C
There is a maximum capacity of humidity air can hold in a given set of conditions of weather. When the water vapour content increases beyond this point, it results in its condensation. This results in many types of natural phenomena like clouds, mist, fog, etc.
Question 269. The amount of actual water vapor of air is known as-
  1.    absolute humidity
  2.    dew point
  3.    relative humidity
  4.    condensation point
 Discuss Question
Answer: Option C. -> relative humidity
:
C
Ans. (c)
Question 270. When it rains the relative humidity in the atmosphere is-
  1.    0 percent
  2.    50 percent
  3.    75 percent
  4.    100 percent
 Discuss Question
Answer: Option D. -> 100 percent
:
D
Ans. (d)
