Concept:Desert:It is an arid region characterized by extremely high or low temperatures and has scarce vegetation.Explanation:Hot desert:The climate of the hot desert is scorching hot and parched dry.It has a short rainy season, it does not show a significant seasonal effect.The sky is cloudless and clear.Here, the moisture evaporates faster than it accumulates.Days are unbelievably hot.The temperatures during the day may soar as high as 50°C, heating up the sand and the bare rocks, which in turn radiates heat making everything around hot.Hot Desert sand is a very faint and slightly pigmented reddish yellow colour that closely resembles the colours of sand, so we can say that hot deserts are red or orange in colour.The nights may be freezing cold with temperatures nearing zero degrees.An example of a hot desert is Sahara.Cold desert:The climate is extremely cold and dry.The air at this altitude is so thin that the heat of the sun can be felt intensely.The day temperatures in summer are just above zero degrees and the night temperatures are well below €œ30°C.It is freezing cold in the winters when the temperatures may remain below €œ40°C for most of the time. There is little rainfall, as low as 10 cm every year.The area experiences freezing winds and burning hot sunlight.Its land is covered in sand, ice, or snow, and it seems grey in colour.Cold deserts experience significant seasonal effects.An example of a cold desert - in Ladakh.Thus, the following statements are true regarding cold and hot deserts:(a) Hot deserts have high temperatures while cold deserts have low temperaturesCorrect(b)hot deserts are battered by the sun and are sandy. Cold deserts have ice and snow-covered ground.Correct.(c)Hot deserts are red or orange while cold deserts are grey.Correct.(d) Hot and cold deserts experience a significant seasonal effect.-Incorrect.IncorrectThe correct option are (a), (b) and (c).
