Arizona Profile Picture
State (Location)


The constituent state of Arizona, US . Arizona is that the sixth largest state within the country in terms of area. Its population has always been predominantly urban, especially since the mid-20th century, when urban and suburban areas began to grow rapidly at the expense of rural areas. Some scholars believe that the name of the state came from a Basque phrase meaning "place of oak", while others ask it because the Tohono ODom (Papago) Indian phrase meaning "young (or slightly) ) Place of Spring. " Arizona attained statehood on Valentine Day , 1912, the last to be admitted to the Union within the 48 us .

Arizona may be a land of contrasts. Although widely regarded for its warm low-elevation desert covered with cacti and creosote shrubs, quite half the state lies at an altitude of a minimum of 4,000 feet (1,200 m) above water level , and includes evergreens. Ponderosa is that the largest stand of pine. Trees within the world. Arizona is documented for its desert waterless routes, but, because of several large man-made lakes, it can have more miles of shoreline than its reputation. Such magnificent landforms because the Grand Canyon and therefore the Painted Desert became international symbols of the regions vulgarity, yet Arizonas climate is so fragile that in some ways its more threatened by pollution, like ny City and l. a. 


Plate tectonics - The shifting and stream erosion of huge , relatively thin sections of the crust have done the foremost to make the spectacular topography of Arizona. especially , the Pacific Plate and North American Plate came into contact and formed major tectonic forces, which extended, stretched, and formed its mountain ranges, valleys, and high plateaus of Arizonas geological crust. During the millennium, rivers and their tributaries have carved distinctive landscaping on these surfaces.

 Arizona Geography

More than 200 miles (320 km) of the southern boundary of the Colorado Plateau is collectively referred to as the Mogollon Rim. To the west and south of the rim, several streams enter the transition zone and basin and range province following narrow valleys or wide valleys to the south. The transition zone bordering the plateaus consists of individual plateau blocks, rugged peaks, and isolated rolling uplands, which forbade them to stay mostly obscure until the late 19th century.


Half of Arizona is alarid, one-third is dry, and therefore the rest is humid. The basin and range area features a dry and semi-subtropical climate that draws most winter visitors and new residents. January in Phoenix receives quite four-quarters of the possible sunshine and features a maximum temperature of 65 ° F (18 ° C). In winter most places within the basin and range area occasionally have mild frost, and a few rainfall disrupts the extremely dry springs and mildly dry springs. Daily maximum readings in Phoenix average 106 ° F (41 ° C) in July and nighttime temperatures average 81 ° F (27 ° C).

The moisture-laden air from the Gulf of California and therefore the Eastern Pacific shows up in July, which is erratic for quite two months but sometimes causes heavy hailstorms locally referred to as the "summer monsoon". Phoenix and Tucson receive about 1 inch (25 mm) of precipitation in July and about 3 inches (75 mm) in total during the summer months. Winter rains occur from the Pacific.

Economy of arizona

Prior to war II the main target of Arizonas economy was primary production - mineral processing , woodworking, cattle raising, and crop growing. From the late 1940s the main target was on manufacturing industry and services, with the economy becoming one that better represented the countrys growing prosperity and technology. this is often very true of the Phoenix area, where a vibrant technology economy has arisen.


many irrigation water, and an extended season enable Arizona to supply cotton, alfalfa, and lots of sorts of grains, vegetables, fruits, and nuts. Arizona is one among the main cotton producers within the country. Citrus growth has been a crucial and expanding a part of the states economy for several years, and until recently, wine producers are successful in growing many sorts of grapes. Livestock products include beef, dairy goods and poultry and eggs. the typical size of farms in Arizona is larger than in the other state, and farmers and ranchers use quite four-quarters of the states water.

Copper, zinc, and, to a minor degree, metal ores, silver and gold have traditionally brought revenue to the state. Coal from the Black Mesa area of the Native American Reservation in northeast Arizona is critical , because coal-fired stations generate an excessive amount of electricity for the southwestern United States; The Northeast region produces small amounts of petroleum also as large quantities of uranium.

Government and society

The Arizona Constitution reflects the ideals of the progressive movement, which was influential at the time of the 1910 Constitutional Convention . It makes provisions for the participation of all citizens on laws and remembers all elected officials, including judges. The reorganization of the government in 1968 strengthened the facility of the governor and streamlined the chief branch. The governor is elected for a four-year term. The Secretary of State, who succeeds for the governorship within the case of a vacancy, holds the second most contested elective office within the state. Other members of the chief branch include the Attorney General, the treasurer , the Superintendent of Public Instruction, the State Mines Inspector, and therefore the five-member Corporation Commission, which oversees public service corporations.

The legislature meets annually and consists of a 60-member House of Representatives and a 30-member Senate; All members provide two years of service. Phoenix and Tucsons large-scale growth, combined with reenactments, has given the urbanized Maricopa and Pima some three-quarters of the seats in both chambers.A constitutional amendment in 1960 reorganized the branch into the Supreme Court, Court of Appeal, Superior Courts and native justice and other courts. The judges of the Supreme Court and therefore the Court of Appeal are appointed by the Governor from nominees selected by a commission. Other judges are appointed or elected.

Resources and power

Metallic ores like copper, zinc, and, to a modest degree, silver and gold traditionally have brought revenue to the state. Coal from the Black Mesa area of the Native American reservations in northeastern Arizona is vital , since coal-fired stations generate much of the electricity for the southwestern United States; the northeastern area also produces alittle amount of petroleum, also as large quantities of uranium.Since the 1880s, northern Arizona’s massive stands of ponderosa have supplied a robust lumber and pulp-paper industry within the state. Rich alluvial soils, particularly in Yuma, Pinal, Pima, and Maricopa counties, have supported large and profitable agricultural operations. The state’s attractive climate and landscape also can be counted among its most precious resources.

Arizona Political Saga

The natural geographic corridor created by the Colorado Plateau along side its Mogollon Rim escarpment has made possible Arizona’s irrigation projects and most of the state’s hydroelectric power, including that generated by the Roosevelt, Hoover, and Glen Canyon dams. Altogether, nearly a dozen dams control the Mogollon Rim’s runoff, impounding and diverting the water to supply control and lakes for water storage. This hydrologic pattern has been a source of much political and legal trouble for Arizona, including years of litigation with California over rights to water from the Colorado River system.

The state’s internal sharing of water is additionally a serious problem because groundwater has been depleted, particularly around Phoenix and Tucson, and there are not any new sources of surface water. Cities have found it necessary to shop for water rights from distant areas, and litigation involving municipalities, Native American tribes, and federal agencies over water rights is increasingly common.
