The temperature experienced in places like idukki and wayanad is lower than that of the neighboring district's Ernakulam and kozhikode respectively. Why?
Answers
Answer:
Idukki and Wayanad are places having a higher altitude (height) than their neighboring districts of Ernakulam and Kozhikode
Explanation:
Going by the elevation numbers given on Wikipedia :
1) Idukki - 1200 m above sea level
2) Wayanad - 700 - 2100m above sea level
3) Ernakulam - 4m above sea level
4) Kozhikode - 1m above sea level
You can very well compare a huge difference between the altitudes of the 4 listed places. Standard Geography books explain that "the temperature in the troposphere decreases uniformly at the rate of 1° C per 165 m of altitude."
NOTICE:
Do not get confused by the fact that Ernakulam and Kozhikode are on coasts whereas Idukki and Wayanad are not -- This influences the Temperature RANGE and not the temperature itself.
Temperature is less in Wayanad because it is located on the mountain of western Ghat about 700 to 2100 above the sea level. This districts experiences typical monsoon climate and make the temperature less as compared to Kozhikode and Ernakulam. The average minimum temperature of Wayanad is 18ᵒC where as minimum average temperature of Kozhikode and Ernakulam is 29ᵒC and 27ᵒC respectively and both districts are located in the costal state of Kerela.
