How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?

In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.

Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger foreasier walking across sandy surfaces, they are taller, to reach higher branches. They have shorter tusks（象牙）, and most importantly, longer trunks to dig for water in riverbeds.

Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families. They drink only every 3 –4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders – they seldom root up trees and break fewer branches, and thus maintain what little food sources are available. Young elephants may even eat the dung（粪便）of the female leader of a group when facing food shortage.

During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine（尿液）to make them muddy!

As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.

At first, the earth’s surface layer (层 ) was made up of huge blocks of hard, solid rocks.There slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebble(卵石) and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remain mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.
There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layer of the rock are slowly worn away. These leave holes and crack(裂缝) in the rock, which become bigger and finally the rock breaks up into smaller pieces.
The moving water of streams and rivers also help to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones, Thus, the larger rocks are worn down to smaller pieces.
The heat of the sun also help to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil.  Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and cracks become wider, and finally break into smaller pieces.
