SCIENCE SOCIAL SCIENCE 1. Imagine that your class is going on an expedition into the Sahara Desert. What means of transport would you use? What kind of clothing would you need? How much food and water would you have to take with you? Think about the ways in which you would have to adapt to be able to survive for a month in a desert. 2. You could also plan a similar expedition to a cold desert, such as the Gobi Desert. What change would you need to make to your supplies and equipment? 3. Find out more about animals and plants which live in the desert. How are they adapted to live in intense heat, or in the case of animals and plants living in cold deserts, how are they adapted to loving in sub-zero temperatures during winter and the heat of the summer? How do they survive very little water
Answers
Answer:
It is difficult to live in the desert as it is very hot so there will be no water,plants cannot grow as hey need water or rain and soil to grow so there wont be food for us to eat and there is rarely some shade to hid under.
By staying in the shade, limiting activity to cooler times such as night and using your available water, your chances for survival increase greatly. Sipping water does not get it to the brain and vital organs. Take a good drink when you need it. People have been found dead from dehydration with water in their canteens.The oasis in the Sahara and the Nile Valley in Egypt support settled life.Complete answer:Camel is called the ship of the desert. There are two types of camels which are found in hot deserts namely one humped or “dromedary camels and two humped Bactrian camels.
hope it help to you plz ask more questions to me after this
thankyou have a nice a day
Living in the desert is challenging because it is extremely hot, making it impossible to grow plants that need water, soil, or rain to grow, which means there won't be any food for us to eat. In addition, there is rarely any shade to hide in, making it tough to stay cool.
One's chances of surviving significantly improve if one stays in the shade restrict your activity to cooler times of day, such as the night, and uses water that is readily accessible. Water does not reach the brain and other important organs by sipping it. When you're thirsty, have a delicious beverage. Despite having water in their canteens, people have been discovered dead from dehydration. Both the Saharan oasis and the Nile Valley in Egypt are favourable to established living.
Camels are called ships of the desert. There are two types of camels found in hot deserts namely one-humped or “dromedary camels and two-humped Bactrian camels.
Animals that live in deserts that are either cold or temperate have thick exoskeletons to shield them from the chilly winds.
In order to stay warm during the chilly winters, Bactrian camels living in the Gobi and Takla Makan deserts grow thick, coarse, hairy coats, which they shed as summer approaches. To keep sand out of their eyes and noses, Bactrian camels also develop thick eyebrows, eyelashes, and nostril hair.
Many reptiles dwell in the chilly deserts, like Bactrian camels. They frequently have dense, spiny exoskeletons to stop water loss, and their cold blood maintains body temperature in accordance with ambient temperature.Animals with thick fur coats, like Peruvian foxes, are shielded from chilly winds. Animals living in the cold desert have a coat of fat that serves as insulation to keep their body heat in.
Animals utilise camouflage as a means of survival to keep themselves safe from harm. The buildup and melting of snow significantly alters the appearance of cold deserts. Many animals from the freezing desert biome camouflage to blend in with their shifting surroundings.
The ptarmigan bird serves as a prime illustration of this. During the warm summers when the surroundings are muddy and brown, ptarmigans have feathers that are brownish. During the winter months, when the ground is blanketed in snow, the bird moults into white feathers.
Burrowing during severe weather is a typical adaption of animals living in temperate deserts. Animals like lizards, snakes, and rodents use their body heat to warm themselves by burrowing under thick layers of sand.
Cold deserts are just as dry and water-scarce as hot deserts, therefore desert animals must preserve water in their bodies. It is common knowledge that Bactrian camels have two humps on which fat is stored and later transformed into water and energy.
Animals that live in the cold desert biome are uricotelic, which means that they use uric acid instead of urea in their excretions to keep water in their bodies.
To deal with a lack of water and how to deal with temperature variations are the two fundamental adaptations that desert animals must make. Many desert animals simply avoid the desert's heat by avoiding it as much as they can.
Due to the scarcity of water, the majority of desert animals obtain their water from the food they consume, including saline plants, seeds, or the blood and body parts of their prey.
Desert animals use a variety of strategies to keep water from escaping their bodies. Some, like kangaroo rats and lizards, reside in burrows with more humid (damp) air and moderate temperatures. During the sweltering days, these animals stay inside their burrows and come out at night to feed.
Other creatures have bodies that are built to conserve water. The thick exterior shell of scorpions and wolf spiders prevents moisture loss. Desert animals' kidneys concentrate urine so they expel less water.
