What is the name of the phenomenon where the wind speed changes with altitude?
A. Wind backing
B. Wind gradient
C. Wind veering
D. Wind shear
Answer: Option B
Solution (By JKExamLibrary)
Wind gradient is the change in wind speed with altitude. Near the surface, friction reduces wind speed; at higher altitudes, wind speed generally increases.
Explanation:
The greenhouse effect is caused by greenhouse gases (CO2, methane, water vapor, etc.) in the atmosphere that trap outgoing longwave (infrared) radiation, warming the planet.
