<The Sahara is the world's second largest desert (second to Antarctica), over 9,000,000 km² (3,500,000 mi²), located in northern Africa and is 2.5 million years old. The entire land area of the United States of America would fit inside it. Its name, Sahara, is an English pronuciation of the word for desert in Arabic (صحراء ).\nOverview\nThe boundaries of the Sahara are the Atlantic Ocean on the west, the Atlas Mountains and the Mediterranean Sea on the north, the Red Sea and Egypt on the east, and the Sudan and the valley of the River Niger on the south. Sahara is divided into western Sahara, the central Ahaggar Mountains, the Tibesti massif, the AﲠMountains (a region of desert mountains and high plateaus), Tenere desert and the Libyan desert (the most arid region). The highest peak in the Sahara is Emi Koussi (3415 m) in the Tibesti Mountains in northern Chad.The Sahara divides the continent into North and Sub-Saharan Africa. The southern border of the Sahara is marked by a band of semiarid savanna called the Sahel; south of the Sahel lies the lusher Sudan.\nHumans have lived on the edge of the desert for almost 500,000 years. During the last ice age, the Sahara was a much wetter place, much like East Africa, than it is today. Over 30,000 petroglyphs of river animals such as crocodiles survive in total with half found in the Tassili n'Ajjer in southeast Algeria. Fossils of dinosaurs have also been found here. The modern Sahara, though, is generally devoid of vegetation, except in the Nile Valley and at a few oases and in some scattered mountains and has been this way since about 3000 BC.\n\n2.5 million people live in the Sahara, most of these in Mauritania, Morocco and Algeria. Dominant groups of people are the Tuareg-Berber, the Sahrawis, Moors, and different black African ethnicities including the Tubu, the Nubians, the Zaghawas and the Kanuri. The largest city is Nouakchott, Mauritania's capital. Other important cities are Tamanrasset, Algeria; Timbuktu, Mali; Agadez, Niger; Ghat, Libya; and Faya, Chad.

Question 1. \nExample 1-Navajo Sandstone Formation, Jurassic, covers large areas of the Colorado Plateau-including Zion National Park). The most characteristic feature of this formation is that it has thick deposits of well-sorted quartz sandstone with big cross beds(sedimentary structures)--indicating that the sand was deposited by wind as dunes, in a giant sand sea (think Sahara).\nhttp://www.agiweb.org/geotimes/nov03/NN_navajo.htm\nExample 2: \nRadiolarian chert of the Franciscan Complex, California. Jurassic and Cretaceous. Good outcrops in the Marin Headlands, north side of Golden Gate bridge, in the Golden Gate National Recreation Area. Thinly bedded maroon to pale green alternating layers of chert and siliceous mudstone.  The chert is chock-full of pin-head size radiolarian fossils--radiolarians are open-ocean marine plankton--but has no shallow marine fossils or calcareous plankton These sediments were deposited in deep water in the open ocean. Since they sit on basalt, it has been inferred that they were deposited on ocean crust. \nExample 3: \nFossiliferous Permian limestone, Texas, Capitan Reef in Guadalupe Mountains National Park\n"Over millions of years, calcareous sponges and algae combined with other lime-secreting marine organisms and vast quantities of lime that precipitated directly from the seawater to form the 400-mile-long, horseshoe-shaped Capitan Reef." --http://www2.nature.nps.gov/geology/parks/gumo/\nCompare to warm, shallow Great Barrier Reef of Australia.\nExample 4: \nCretaceous Cedar Mountain Formation in Dinosaur National Park.  A 2002 study of rocks types, textures, and sedimentary features lead a group of researchers to conclude that the paleoenvironment was generally arid to semi-arid terrestrial with occasional flashy, extreme rainfall events. \nhttp://gsa.confex.com/gsa/2002AM/finalprogram/abstract_46144.htm\nExample 5: \nMoraine deposits all over the Great Lakes area are evidence for continental glaciers during the Ice Ages.\n\nQuestion 2: \nNumerical Age dating\nhttp://www.gpc.edu/~pgore/geology/geo102/radio.htm\nhttp://pubs.usgs.gov/gip/geotime/radiometric.html\nhttp://en.wikipedia.org/wiki/Radiometric_dating \nQuestion 3:\nAs for "what kind of information is given by a rock?" --partly answered here already.  A rock may give information useful for determing one or more of  the following: Age, tectonic setting and history of formation, paleoenvironment, climate information, biological history of life info (if fossiliferous), paleolatitude, etc.

A desert is defined by its low rainfall record, hence why you can get hot, cold and frigid deserts.\n\nDeserts can be caused by a number of factors, for example mountains surrounding the area cause rain to fall on their slopes rather than further inland so creating the arid conditions.(can't think of an example for this but there are several)\n\nThe area may be so far inland that the damp winds from the sea fail to reach it.  When combined with a hot climate severe desert conditions occur. (Death Valley)\n\nThere may be a cold current running along the coast which causes coastal fog and precipitation, preventing it raining inland. (Patagonian Desert)\n\nThe sand is the product of weathering on the rock, the hot temperatures during the day cause the rocks to expand, the rocks are made up of different minerls and colours of crystals (grains) due to colour some expand more than others, this can break the rock surface down. (Intergranular errosion).  The wind picks up the bits and hits them against other rocks, turning the lumps to powder (mechanical errosion).\n\nwhen rain does fall the water scours rock debris off the surface causing the pieces to rub over each other (more mechanical errosion).  When drying out in the heat the water evapourates leaving salt deposits behind, these can dissole minerals in the rock (chemical errosion) and can cause slat pillars which are capable of lifting erroded rock layers off the surface.

Deserts can be either HOT or COLD. Antartica is also a desert.\n\nIn geography, a desert is a landscape form or region that receives little precipitation. Generally deserts are defined as areas that receive an average annual precipitation of less than 250 mm (10 inches).\n\nDeserts have a reputation for supporting very little life. Compared to wetter regions this may be true, although deserts often have high biodiversity, including animals that remain hidden (especially during the daylight) to preserve moisture. About one-fifth of Earth's land surface is desert.\n\nDesert landscapes have certain features. Deserts are often composed of sand and rocky surfaces. Sand dunes called ergs and stony or hamada surfaces compose a minority of desert surfaces. Exposures of rocky terrain are typical, and reflect minimal soil development and sparseness of vegetation. Bottom lands may be salt-covered flats. Eolian (wind-driven) processes are major factors in shaping desert landscapes. Cold deserts have similar features but the main form of precipation is snow rather than rain. The largest cold desert is Antarctica (composed of about 98 percent thick continental ice sheet and 2 percent barren rock). The largest hot desert is the Sahara.

I love it when Jenny's on top!  But enough of that!\n\nI would focus on the geography of Arizona.  It is one of the few states that has pine-tree forests, high altitude grasslands (think African plains), deserts, lakes, mountains and rivers.  Flagstaff is the highest city in the US!  (8000 ft.)  Not to mention the obvious stuff like the Grand Canyon, Meteor Crater, and Sedona.  The Sonora Desert in the southern part of the state is truly one of a kind in all of the world.  Wildlife is abundant.  We have mountain lions, bears, wild turkey, elk, deer, rattlesnakes, loads of insects and spiders, all kinds of fish, and even mountain goats and parrots.  Arizona is even getting famous for some local wines.  Here are some good websites for info:

The United States has several large deserts.  The main ones are the Mojave, the Great Basin, the Chihuahuan and the Sonoran.  Each on has differnt types of plant and animal life that differentiate them from the others.  There are far too many facts to mention about deserts without knowing exactly what you are looking for so I am going to post a source for more info.

Basically all of the surface of Mars except small ice caps (frozen CO2) qualifies as desert - no free water, no rain. The major geographic (or areographic, from Ares - Greek for Mars) features were named after elevations etc. when all the information about Mars came  from early telescopes.\n\nThe Wikipedia article linked below has a topographic map.
