A) 15° B) 30° C) 45° D) 60°

Discuss

Answer & Solution

Answer: Option B

Solution:

One hour of time difference corresponds to 15° of longitude (360°/24 hours = 15°/hour). Therefore, For a time difference of two hours, he longitudinal distance will be equal to 30°.

A) Air capacity of vaporization reduces with the rise in the temperature of air. B) Atmospheric pressure reduces due to rise in temperature. C) Relative humidity is denoted in gram per cubic meter of air. D) Temperature decreases 10°C at every 165 height

Discuss

Answer & Solution

Answer: Option B

Solution:

Air pressure is the weight of air molecules pressing down on you. Inhabitants on Earth’s surface bear the weight of all the air molecules in the atmosphere. At higher altitudes, air pressure decreases because there are fewer air molecules pressing down from above and temperature increases compared with the air pressure at sea level.
