Question 1. A camel can do without water for days together. What is the reason given in the text?
Answer: The camels can do without water for days together because they sweat very little. They can stand a high body temperature. They do not need to sweat. Therefore, they can retain the water they drink for long periods of time.
Question 2. How do the smaller desert animals fulfill their need for water?
Answer: The smaller animals fulfill their need for water by burrowing underground during the hot day and come out at night to eat. Some of them eat other animals and get the water they need from the moisture in the meat. Others eat plants and seeds and get the water they need from plant juices.
Question 3. In a desert the temperature rises during the day and falls rapidly at night. Why?
Answer: In humid climates, the moisture in the air acts like a blanket and protects the earth’s surface from the hot rays of the sun. The absence of this blanket in desert lands causes the desert to heat up rapidly during the day and to cool off rapidly at night.
Do the following activities in groups.
Question 1. Describe a desert in your own way. Write a paragraph and read it aloud to your classmates.
Answer: A desert is a place which is hot and receives less rainfall. It is not entirely dry. Oasis is a green island in the desert where a well/ spring gives water to the plants around. Camels can store water for a long time. Thus, they can survive on deserts for long. That’s the reason camel is called the ship of the desert.
