Deserts

Not quite sure- sorry

There are eight communities within the Anangu Pitjantjatjara Lands. The main communities in the region are Aparawatatja (Fregon, pop.310), Pukatja (Ernabella, pop. 470), Amata (pop.370), Iwantja (Indulkana, pop.320), Mimili (pop. 220) and Pipalyatjara (pop.140).

The Simpson desert contains many types of vegetation including the Barrel Cactus, Organ Pipe Cactus. Saguaro Cactus, Prickly Pear Cactus.

Yes, there are several species of barrel cacti that live in the Chihuahuan Desert.

95% of the Arabian peninsula is desert

The California desert region is hot. There is an abundance of sand. Rocks are also commonplace in this area.

The Baja California Desert is a Desert ecoregion of Mexico's Baja California Peninsula.

The Chihuhuan Desert occasionally drops below freezing for a few hours on some winter nights. However, the Colorado Plateau Desert in the northwestern part of the state may drop well below zero degrees F. It is known as a cold winter desert.

[Original Answer:] it is very big in fact much bigger than england, 2,008 km² in fact.

[Updated Answer:] The Sonoran Desert is the third largest of North America's four main deserts. It spans over 120,000 square miles (312,000 square km) and covers parts of California, Arizona, and extends into Mexico.

The temperature depends on the season of the year and location. In the summer the temperature can exceeds 120 degrees F in the southern deserts of the state. In the winter the temperature can drop well below 0 degrees F at night in the northern desert areas.

Water comes from rivers, reservoirs and wells. Some water is also produced at desalination plants.

The Libyan Desert covers those areas mentioned in your question. It is a sub region of the larger Sahara.

The desert is usually not humid unless it happens to be during the rainy season. I live in the desert and yesterday our humidity was 2% with a dewpoint of minus 26 degrees F. That is about as dry as one can find.

Cacti are natives to the Americas only. However, some 'wise' people decided to introduce the prickly pear to some of Australia's deserts. Since the cactus plants in Australia did not have any natural enemies, they have rapidly spread and become an unwelcome invasive species.

The Arabian Desert is classified as an hyper-arid desert. Rainfall is about 35 mm, (1.38") per year.

People do more than exist in the desert, they thrive. Millions and millions of people around the world live in cities and towns in deserts. Look at such cities as these:
Cairo, Egypt
Las Vegas, Nevada
Palm Springs, California
Phoenix, Arizona
Tucson. Arizona
El Paso, Texas
Cd. Juarez, Mexico
Chihuahua, Mexico
Hermosillo, Mexico
Antofogasta, Chile
Arica, Chile
and many, many more.

An oasis,

The largest Polar desert is in ... Antarctica!

Yes, Gila monsters are found i parts of the Chihuhuan Desert, the Sonoran Desert and the Mojave Desert.

Temperatures vary greatly between night and day in many desert regions. Typically, humidity blocks the sun's radiation. Since deserts have little to no humidity, about twice the radiation is absorbed. At night, a greater amount of heat is lost due lack of humidity. This can bring temperatures well below freezing, especially during the winter months.

Hot tropical deserts - examples:

1.) Sahara,

2.) Thar Desert,

3.) Sonoran Desert,

4.) Great Victorian Desert,

5.) Mojave Desert,

6.) Gibson Desert,

7.) Arabian Desert,

others

The sand dunes act as a natural barrier, blocking strong winds.

It was an ancient barrior. :)-smiley face

Although from a distance, it may seem that the "Southwest" is all one place and culture in fact there are very different people, languages, lifestyles and climate in this area.

The geography and climate differs greatly with elevation some in general those in the mountains and high Colorado Plateau have a very different place to live than the low land Sonoran Desert areas. There was also a large difference between people who farmed and people who didn't. Among the farmers a steady supply of water versus not changed what they could farm. Living is a settled town or trading center effected how you ate. Being a herder of livestock or not did too.

The first big group was the many Pueblo Indian peoples. Although they were from many unrelated language groups they shared much. They all had corn, beans and squash and sunflower as their main crops and food. After the mid 1500s they had chillies, onions, melons and peaches too. Taos, Pecos and Zuni were huge trade centers, the hub of trade from as far away as central Mexico and the northern plans and the Pacific Ocean, Gulf of Mexico and Sea of Cortez.

So they had access to dried bison and elk and deer and after 1540 or so sheep and cattle. The type of crops grown was a bit different from east to west because the western Pueblos did not irrigate for the most part. They as everyone else ate wild food too such as pinon pine nuts, rabbit, prairie dog, wild greens, wild potato, yucca and cactus fruit, berries of many types.

The Navajo grew corn, beans and squash but lived spread out not in towns. After the 1540s they raised sheep and goats. They also added chillies, peaches and melons and other crops in the 1600s. They traded at the trading centers but did not live in them.

The Lipan and Kiowa Apache, and Comanche lived a a more Plains Indian life and buffalo was important to them. The Comanche ran the trade that came from the east in the French and Caddo lands.

The Ute hunted game elk, deer, rabbits, bison and foraged in the mountains and Colorado Plateau. After they gained the horse they lived and ate more like the Plains peoples.

Most of the other Apache foraged for wild food although they grew some corn. What they ate depended on their environment. For example, the Mescalero Apache are called that because their staple food was the mescal agave.

The Pima and the Tohono O'odam (Papago) farmed flood plains and grew beans, squash corn and later wheat in them. They ate deer, rabbit, birds fish mesquite beans, saguaro fruit, cholla buds, and prickly pear fruit and berries and wild greens.

The the different Pai peoples grew crops like the Hopi but spent the other half the year foraging for wild crops.

The Paiute foraged for wild food.

The Quechan or Yuma ran trade route to the Pacific and practiced agriculture where the environment allowed and gathered other places.

The Genízaro people are the descendants of native of Spanish captives. They were about 1/3 of the population of New Mexico in the late 18th century. They had lost their different tribal identities and ate a colonial Spanish diet.
