Black Belt (geological Formation)
Black Belt is a physical geography term referring to a roughly crescent-shaped geological formation of dark fertile soil in the Southern United States. It is about long and up to wide in c. east–west orientation, mostly in central Alabama and northeast Mississippi. During the Cretaceous period, about 145 to 66 million years ago, most of what are now the central plains and the Southeastern United States were covered by shallow seas. Tiny marine plankton grew in those seas, and their carbonate skeletons accumulated into massive chalk formations. That chalk eventually became a fertile soil, highly suitable for growing crops. The Black Belt arc was the shoreline of one of those seas, where large amounts of chalk had collected in the shallow waters. History Before the 19th century, this region was a mosaic of prairies and oak-hickory forest. In the 1820s and 1830s, the region was identified as prime land for upland cotton plantations. Short-staple cotton did well here, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Geography
Physical geography (also known as physiography) is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere. This focus is in contrast with the branch of human geography, which focuses on the built environment, and technical geography, which focuses on using, studying, and creating tools to obtain, analyze, interpret, and understand spatial information. The three branches have significant overlap, however. Sub-branches Physical geography can be divided into several branches or related fields, as follows: * Geomorphology is concerned with understanding the surface of the Earth and the processes by which it is shaped, both at the present as well as in the past. Geomorphology as a field has several sub-fields that deal with the specific landforms of various environments, e.g. desert geomorphology and ...

Cotton Gin
A cotton gin—meaning "cotton engine"—is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation.. Reprinted by McGraw-Hill, New York and London, 1926 (); and by Lindsay Publications, Inc., Bradley, Illinois, (). The separated seeds may be used to grow more cotton or to produce cottonseed oil. Handheld roller gins had been used in the Indian subcontinent since at earliest 500 and then in other regions. The Indian worm gear, worm-gear roller gin was invented sometime around the 16th century and has, according to Lakwete, remained virtually unchanged up to the present time. A modern mechanical cotton gin was created by English-American inventor Eli Whitney in 1793 and patented in 1794. Whitney's gin used a combination of a wire screen and small wire hooks to pull the cotton through, while brushes continuously removed the loose cotton lint to prevent jams. It revolutionized the cotton indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologic Formations Of The United States
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the evolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Civil War
The American Civil War (April 12, 1861May 26, 1865; also known by Names of the American Civil War, other names) was a civil war in the United States between the Union (American Civil War), Union ("the North") and the Confederate States of America, Confederacy ("the South"), which was formed in 1861 by U.S. state, states that had Secession in the United States, seceded from the Union. The Origins of the American Civil War, central conflict leading to war was a dispute over whether Slavery in the United States, slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction. Timeline of events leading to the American Civil War, Decades of controversy over slavery came to a head when Abraham Lincoln, who opposed slavery's expansion, won the 1860 presidential election. Seven Southern slave states responded to Lincoln's victory by seceding f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bible Belt
The Bible Belt is a region of the Southern United States and the Midwestern state of Missouri (which also has significant Southern influence), where evangelical Protestantism exerts a strong social and cultural influence. The region has been described as the most socially conservative across the United States due to a significant impact of Protestant Christianity on politics and culture. The region is known to have a higher church attendance, more evangelical Protestant denominations, and greater emphasis on traditional religious values compared to other parts of the country. The region contrasts with the religiously diverse Midwest and Great Lakes and the Mormon corridor in Utah, southern Idaho, and northern Arizona. Whereas the states with the highest percentage of residents identifying as non-religious are in the West and New England regions of the United States (with Vermont at 37%, ranking the highest), in the Bible Belt state of Alabama it is just 12%, while Tennesse ...

Sun Belt
The Sun Belt is a region of the United States generally considered stretching across the Southeast and Southwest. Another rough definition of the region is the area south of the Parallel 36°30′ north. Several climates can be found in the region—desert/ semi-desert ( Eastern California, Nevada, Arizona, New Mexico, Utah, and West Texas), Mediterranean (California), humid subtropical (Alabama, Mississippi, Louisiana, Florida, Georgia, South Carolina, North Carolina, Tennessee and Texas), and tropical (South Florida). The Sun Belt has seen substantial population growth post-World War II from an influx of people seeking a warm and sunny climate, a surge in retiring baby boomers, and growing economic opportunities. The advent of air conditioning created more comfortable summer conditions and allowed more manufacturing and industry to locate in the Sun Belt. Since much of the construction in the Sun Belt is new or recent, housing styles and design are often modern and open. R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rust Belt
The Rust Belt, formerly the Steel Belt or Factory Belt, is an area of the United States that underwent substantial Deindustrialization, industrial decline in the late 20th century. The region is centered in the Great Lakes and Mid-Atlantic (United States), Mid Atlantic regions of the United States. Common definitions of the Rust Belt include Ohio, Indiana, Northern Illinois, southeastern Wisconsin, Michigan, Pennsylvania, and Upstate New York. Some broader geographic definitions of the region include parts of Central Illinois, Iowa, Kentucky, Maryland, Minnesota, Missouri, New Jersey, and West Virginia. The term "Rust Belt" is considered to be a pejorative by some people in the region. Between the late 19th century and late 20th century, the Rust Belt formed the industrial heartland of the country, and its economies were largely based on Iron and steel industry in the United States, iron and steel, Automotive industry in the United States, automobile production, Coal mining in t ...

Snow Belt
The Snowbelt, Snow Belt, Frostbelt, or Frost Belt is the region near the Great Lakes in North America where heavy snowfall in the form of lake-effect snow is particularly common. Snowbelts are typically found downwind of the lakes, principally off the eastern and southern shores. Cause Lake-effect snow occurs when cold air moves over warmer water, taking up moisture that later precipitates as snow when the air moves over land and cools. The lakes produce snowsqualls and persistently cloudy skies throughout the winter, as long as air temperatures are colder than water temperatures, or until a lake freezes over. Location In the United States, snowbelts are located southeast of Lake Erie from Cleveland, Ohio, to Buffalo, New York, and south of Lake Ontario stretching roughly from Rochester, New York, over Syracuse, New York, to Utica, New York, and northward to Watertown, New York. Other snowbelts are located on the eastern shore of Lake Michigan from Gary, Indiana, northward th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geopolitics
Geopolitics () is the study of the effects of Earth's geography on politics and international relations. Geopolitics usually refers to countries and relations between them, it may also focus on two other kinds of State (polity), states: ''de facto'' independent states with List of states with limited recognition, limited international recognition and relations between Administrative division, sub-national geopolitical entities, such as the federated states that make up a federation, confederation, or a quasi-federal system. At the level of international relations, geopolitics is a method of studying foreign policy to understand, explain, and predict international political behavior through geographical variables. These include area studies, climate, topography, demography, natural resources, and applied science of the region being evaluated. Geopolitics focuses on political power linked to geographic space, in particular, territorial waters, List of sovereign states, land territ ...

Long-staple Cotton
''Gossypium hirsutum'', also known as upland cotton or Mexican cotton, is the most widely planted species of cotton in the world. Globally, about 90% of all cotton production is of cultivars derived from this species. In the United States, the world's largest exporter of cotton, it constitutes approximately 95% of all cotton production. It is native to Mexico, the West Indies, northern South America, Central America and possibly tropical Florida. Archeological evidence from the Tehuacan Valley in Mexico shows the cultivation of this species as long ago as 3,500 BC, although there is as yet no evidence as to exactly where it may have been first domesticated. This is the earliest evidence of cotton cultivation in the Americas found thus far. ''Gossypium hirsutum'' includes a number of varieties or cross-bred cultivars with varying fiber lengths and tolerances to a number of growing conditions. The longer length varieties are called "long staple upland" and the shorter length varie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-staple Cotton
The history of agriculture in the United States covers the period from the first English settlers to the present day. In Colonial America, agriculture was the primary livelihood for 90% of the population, and most towns were shipping points for the export of agricultural products. Most farms were geared toward subsistence production for family use. The rapid growth of population and the expansion of the frontier opened up large numbers of new farms, and clearing the land was a major preoccupation of farmers. After 1800, cotton became the chief crop in southern plantations, and the chief American export. After 1840, industrialization and urbanization opened up lucrative domestic markets. The number of farms grew from 1.4 million in 1850, to 4.0 million in 1880, and 6.4 million in 1910; then started to fall, dropping to 5.6 million in 1950 and 2.2 million in 2008.
