Question

How have people adapted to living in the hot deserts? -For a geography assignment, thanks-

Answer 1

Answer:

hey mate

Explanation:

Traditional adaptations to arid conditions

One example of people who live in the desert is the Bedouin tribe. ... They have herds of animals which are adapted to living in desert conditions, such as camels. Their tents are built to allow air to circulate within them, keeping them cool.

Modern adaptations to arid conditions

With both money and technology, desert areas can be developed to cater for modern lifestyles. Las Vegas, in the Mojave Desert, is one of the fastest-growing cities in the USA. The city of Las Vegas is lush and green in comparison with the surrounding desert.

This is possible because 90 per cent of the water Las Vegas needs is imported from the Colorado River. The remaining 10 per cent comes from ground water. The demand for water is not sustainable and the city has started to plan to reduce the demand for water. One way is that new homes have restrictions on the amount and type of lawns that they can have. The authority also recycles water where it can.

Climatic adaptation, in physical anthropology, the genetic adaptation of human beings to different environmental conditions. Physical adaptations in human beings are seen in response to extreme cold, humid heat, desert conditions, and high altitudes.

heat adaptation:

adaptation to humid heat and to dry heat (desert conditions). In hot climates the problem is not in maintaining body heat but in dissipating it. Ordinarily the body rids itself of excess heat by sweating. In conditions of humid heat, however, the humidity of the surrounding air prevents the evaporation of perspiration to some extent, and overheating may result. Hence, the heat-adapted person in humid climates is characteristically tall and thin, so that he has maximum surface area for heat radiation. He has little body fat; often a wide nose, since warming of the air in the nasal passages is not desirable; and usually dark skin, which shields him from harmful solar radiation and may serve to lower his sweating threshold. The desert-adapted person can sweat freely but must deal with the water loss involved; hence, he is usually thin but not tall. This adaptation minimizes both water needs and water loss. Skin pigmentation is moderate since extreme pigmentation is good protection from the sun but allows absorption of heat, which must be lost by sweating. Adaptation to night cold is also common in desert-adapted people.

High altitudes demand a degree of cold adaptation plus adaptation for low air pressure and the consequent low oxygen. This adaptation is accomplished by an increase in lung tissue generally.
