- Question 1 of 5
1. Question
Consider the following statements regarding Thunderstorms:
1. They occur over a small area but are violent in nature.
2. A thunderstorm is a well-known cirrocumulus cloud producing thunder and lightning.
3. When the clouds extend to heights where sub-zero temperature prevails, thails are formed and they come down as hailstorms.
Which of the statements given above is/are correct?CorrectCorrect Answer: a) 1 and 3 only
Explanation :
• Statement 1: Thunderstorms are localized phenomena, typically affecting small areas, and are characterized by violent weather (thunder, lightning, heavy rain, etc.). This is correct.
• Statement 2: Thunderstorms are associated with cumulonimbus clouds, not cirrocumulus clouds. Cirrocumulus clouds are high-altitude, thin clouds that do not produce thunderstorms. This is incorrect.
• Statement 3: When cumulonimbus clouds extend to heights with sub-zero temperatures, water droplets freeze into ice (likely a typo: “thails” means “hail”). This leads to hailstorms. This is correct.

- Question 2 of 5
2. Question
Consider the following statements:
1. The actual amount of water vapour present in the atmosphere is known as Absolute Humidity.
2. Relative humidity is defined as the percentage of moisture present in the atmosphere as compared to its full capacity at a given temperature.
Which of the statements given above is/are correct?
CorrectCorrect Answer: c) Both 1 and 2
Explanation :
• Statement 1: Absolute humidity is indeed the actual amount of water vapor present in a unit volume of air (typically measured in grams per cubic meter). This is correct.
• Statement 2: Relative humidity is the ratio of the current amount of water vapor in the air to the maximum amount it can hold at a given temperature, expressed as a percentage. This is correct.
IncorrectCorrect Answer: c) Both 1 and 2
Explanation :
• Statement 1: Absolute humidity is indeed the actual amount of water vapor present in a unit volume of air (typically measured in grams per cubic meter). This is correct.
• Statement 2: Relative humidity is the ratio of the current amount of water vapor in the air to the maximum amount it can hold at a given temperature, expressed as a percentage. This is correct.
- Question 3 of 5
3. Question
Consider the following statements regarding subtropical high-pressure belts:
1. From subtropical highs, the air flows towards the equator known as trade winds.
2. The accumulation of ascending equatorial air, which sinks to ground, forms subtropical high-pressure belts.
Which of the statements given above is/are correct?
CorrectCorrect Answer: c) Both 1 and 2
Explanation :
• Statement 1: Trade winds blow from the subtropical high-pressure belts (around 30° N and S) toward the equator. This is correct.
• Statement 2: Subtropical highs are formed by the sinking of air that ascends at the equator in the Hadley cell circulation. The phrasing is slightly awkward (“accumulation of ascending equatorial air”), but the concept is correct.
IncorrectCorrect Answer: c) Both 1 and 2

• Statement 2: Subtropical highs are formed by the sinking of air that ascends at the equator in the Hadley cell circulation. The phrasing is slightly awkward (“accumulation of ascending equatorial air”), but the concept is correct.
- Question 4 of 5
4. Question
Consider the following statements:
1. The chief characteristic of Orographic rainfall is that the windward slopes receive greater rainfall.
2. Rainfall on the leeward side is an example of relief rain.
Which of the statements given above is/are correct?CorrectCorrect Answer: a) 1 only
Explanation :
• Statement 1: Orographic rainfall occurs when moist air rises over a mountain, cooling and condensing on the windward side, leading to higher rainfall there. This is correct.
• Statement 2: Relief rain is another term for orographic rainfall, but the leeward side typically receives less rain (rain shadow effect), not significant rainfall. This is incorrect.
IncorrectCorrect Answer: a) 1 only
Explanation :
• Statement 1: Orographic rainfall occurs when moist air rises over a mountain, cooling and condensing on the windward side, leading to higher rainfall there. This is correct.
• Statement 2: Relief rain is another term for orographic rainfall, but the leeward side typically receives less rain (rain shadow effect), not significant rainfall. This is incorrect.
- Question 5 of 5
5. Question
A relief which divides two areas drained by the river is known as:
CorrectCorrect Answer: a Watershed
Explanation :
• A watershed (or drainage divide) is a ridge or elevated area that separates two drainage basins or river systems. This fits the description perfectly.
• A river basin is the area drained by a river, not a dividing feature.
• Drainage pattern refers to the arrangement of rivers, not a dividing relief.
• Water management is unrelated.
