Question

In which one of the following habitats does the diurnal temperature of soil surface vary most?

• A. Forest
• B. Desert
• C. Grassland
• D. Shrub land

Answer 1

The correct option is B Desert

Diurnal temperature variation is a meteorological term that relates to the variation in temperature that occurs from the highs and lows during the day. Peak daily temperature generally occurs after noon, as air keeps absorbing heat even after noon and similarly minimum daily temperature generally occurs substantially after midnight, occurring during early morning in the hour around dawn, since heat is lost all night long. Diurnal temperature variations are greatest very near the Earth's surface. High desert areas have the greatest diurnal temperature variations. Low lying, humid areas have the least.

So, the correct answer is 'Desert'
