Q1.
What is the study of atmospheric phenomena called?
Climatology
Meteorology
Hydrology
Oceanography
Show answer
Answer: B. Meteorology
The study of atmospheric phenomena is called Meteorology. It deals with weather patterns, atmospheric conditions, and related phenomena.
Q2.
What is the extent of atmosphere from sea level?
50 km to 500 km
90 km to 1,000 km
100 km to 800 km
80 km to 900 km
Show answer
Answer: B. 90 km to 1,000 km
The atmosphere extends from sea level to a height of 90 km to 1,000 km above the surface.
Q3.
What percentage of water vapor is present in the atmosphere's total volume?
2 to 3 percent
4 to 5 percent
6 to 7 percent
1 to 2 percent
Show answer
Answer: B. 4 to 5 percent
Water vapor constitutes 4 to 5 percent of the atmosphere's total volume, varying from 1% in polar regions to 4% in hot-humid areas.
Q4.
What is the percentage of water vapor in polar regions?
4%
2%
1%
3%
Show answer
Answer: C. 1%
In polar regions, the water vapor content is approximately 1% due to extremely cold temperatures.
Q5.
What is the percentage of water vapor in hot-humid regions?
1%
2%
3%
4%
Show answer
Answer: D. 4%
In hot-humid regions, the water vapor content reaches up to 4% due to high evaporation rates.
Q6.
Up to what height is the gas composition of atmosphere considered uniform?
40 km
50 km
60 km
70 km
Show answer
Answer: B. 50 km
The gas composition of atmosphere remains uniform up to a height of 50 km from the surface.
Q7.
Which of the following is the primary component of the atmosphere?
Oxygen
Nitrogen
Carbon dioxide
Argon
Show answer
Answer: B. Nitrogen
Nitrogen is the primary component of the atmosphere, constituting about 78% of the total atmospheric gases.
Q8.
What factor primarily controls the distribution of water vapor in the atmosphere?
Altitude
Temperature
Pressure
Wind speed
Show answer
Answer: B. Temperature
Temperature is the primary factor controlling water vapor distribution, as it determines evaporation and condensation rates.
Q9.
Which branch of science deals with the study of weather and atmospheric conditions?
Geology
Meteorology
Astronomy
Hydrology
Show answer
Answer: B. Meteorology
Meteorology is the scientific study of weather patterns, atmospheric phenomena, and climate conditions.
Q10.
What happens to the concentration of water vapor as we move from tropical to polar regions?
Increases
Decreases
Remains constant
First increases then decreases
Show answer
Answer: B. Decreases
Water vapor concentration decreases from tropical to polar regions due to decreasing temperature, which reduces evaporation rates.
