The dry adiabatic lapse rate is approximately: MCQ with Answer and Explanation

The dry adiabatic lapse rate is approximately:
A. 1°C per 100 meters
B. 0.6°C per 1000 meters
C. 1°C per 1000 meters
D. 10°C per 1000 meters
Answer: Option A
Solution (By JKSSB Mock Tests)
The dry adiabatic lapse rate is approximately 1°C per 100 meters (or 10°C per kilometer). This is the rate at which a dry parcel of air cools as it rises.

Question #1
Which of the following is the primary reason for the warm climate of the tropical regions?
A. High angle of solar radiation
B. Distance from the sea
C. High altitude
D. Ocean currents

Correct Answer: Option A


Explanation:
The tropical regions receive direct (high-angle) solar radiation, concentrating sunlight over a small area and providing high energy, resulting in warm temperatures year-round.

Question #3
What is the name of the phenomenon where the temperature in the troposphere decreases with altitude?
A. Greenhouse effect
B. Adiabatic cooling
C. Solar radiation absorption
D. Temperature inversion

Correct Answer: Option B


Explanation:
The decrease in temperature with altitude in the troposphere is due to adiabatic cooling, where air expands and cools as it rises.
