With reference to the cloud formation and precipitation, consider the following statements:
⦁ Condensation takes place only when the temperature of air is below the dew point.
⦁ Condensation takes place only when the temperature of air is lower than the freezing point.
⦁ Frost forms on cold surfaces when the dew point is at or below the freezing point.
⦁ For the formation of dew, it is necessary that the dew point is above the freezing point.
Which of the statements is/are incorrect?
Correct

Consider the following statements regarding different climatic types:
⦁ The China type climate is found in southern Japan.
⦁ Natal type of climate is found in the southern hemisphere only.
⦁ On-shore trade winds play a role in influencing Gulf type of climate.
Which of the above statements are correct?
Correct
Ans d)
The Warm Temperate Eastern Margin/China type:
Found on the eastern margins of continents in warm temperate latitudes, just outside the tropics. The climate is characterized by warm, moist summer and cool, dry winter.
Natal Type:
It consists the entire warm temperate eastern margin (non-monsoonal areas) of the southern hemisphere including Natal (in Brazil), eastern Australia, and southern Brazil—Paraguay—Uruguay and northern Argentina.
Gulf Type:
This type of climate is found in the south-eastern United States. The warm Gulf Stream and the on-shore Trade Winds help to bring about this narrow range of temperature.

Consider the following statements regarding the Malthusian Theory of Population:
⦁ While the food supply increases in geometrical progression, the population increases in arithmetical progression.
⦁ It violates the law of diminishing returns.
⦁ The theory underestimates scientific and technological advancements.
Which of the statements is/are incorrect?
Correct
Ans b)
Statement 1 is incorrect: The food supply increases in arithmetical progression whereas the population increases in geometrical progression.
Statement 2 is incorrect: His theory was based on the law of diminishing returns.
Malthusian Theory of Population:
According to this theory, the human population increases in geometrical progression and if unchecked doubles itself every 25 years. On the other hand, the food supply increases in a slow arithmetical progression due to the operation of the law of diminishing returns based on the supposition that the supply of land is constant. And if unchecked, the population tends to outrun food supply, thus creating an imbalance.

⦁ Polar easterlies change direction according to the local weather and topography.
Which of the above statements is/are correct
Correct
Ans c)
Statement 2 is incorrect: Inter-Tropical Convergence Zone (ITCZ) represents the convergence of northeast and southeast trade winds.
Q 68. Consider the following statements regarding distribution of coal in India:

10. Question

Which among the following are the factors controlling temperature distribution on the earth?
⦁ Latitude
⦁ Longitude
⦁ Ocean currents
⦁ Distance from the sea
Select the correct answer:
Correct
Ans c)
Statement 2 is incorrect: Longitude does not control temperature distribution on the Earth.
Factors Controlling Temperature Distribution:
The Latitude:
The temperature of a place depends on the insolation received. Since the insolation varies according to the latitude, the temperature also varies accordingly.
The Altitude:
The atmosphere is indirectly heated by terrestrial radiation from below. Therefore, the places near the sea-level record a higher temperature than the places situated at higher elevations. In other words, the temperature generally decreases with increasing height.
Distance from the Sea:
Compared to land, the sea gets heated slowly and loses heat slowly. Land heats up and cools down quickly. Therefore, the variation in temperature over the sea is less compared to land. The places situated near the sea come under the moderating influence of the sea and Air-Mass and Ocean Currents.
