22. Who identified a close relationship between the distribution of vegetation and climate?
[A] Hoyle
[B] Henry Hess
[C] Laplace
[D] Koeppen
Show Answer
Correct Answer: D [Koeppen]
Notes:
Koeppen’s classification of Climatic Regions is an empirical classification based on mean annual and mean monthly temperature and precipitation data. He identified a close relationship between the distribution of vegetation and climate. He selected certain values of temperature and precipitation and related them to the distribution of vegetation and used these values for classifying the climates. He recognized five major climatic groups, four of them are based on temperature and one on precipitation.

Causes of Coral Bleaching :
Rise in Temperature
Ocean Acidification
Increased Sedimentation
Chemical Pollution
Infectious diseases
