CLASS VII CHAPTER - 3 THE DESERT

Q1. A camel can do without water for days together. What is the reason given in the text?
Ans. The reason is that the camel sweats little. It can therefore, retain the water it drinks for a longer period of time.

Q2. How do the smaller desert animals fulfill their need for water?
Ans. The smaller animals spend the day in the underground burrows to escape the heat.  Some of them eat other animals and get the moisture contained in the meat. Others eat plants and get the water from plant juices.

Q3. In a desert the temperature rises during the day and falls rapidly at night. Why?
Ans. In humid climates, the air has moisture that protects the earth's surface from the heat of the sun. Since, the desert have no moisture cover, they heat up rapidly during the day and cool off rapidly during the night.
