William Morris Davis
William Morris Davis (February 12, 1850 – February 5, 1934) was an American geographer, geologist, geomorphologist, and meteorologist, often called the "father of American geography". He was born into a prominent Quaker family in Philadelphia, Pennsylvania, son of Edward M. Davis and Maria Mott Davis (a daughter of the women's advocate Lucretia Mott). Davis studied geology and geography at Harvard's Lawrence Scientific School and then joined the Harvard sponsored geographic exploration party to the Colorado territory, led by the inaugural Sturgis-Hooper professor of geology, Josiah Dwight Whitney. Wild stories had circulated since soon after the Louisiana Purchase about Rocky Mountains peaks 18,000 feet or higher. The Harvard expedition set out to investigate, and found none, but they did find "14ers" (14,000-plus feet). He graduated from Harvard University in 1869 and received a Master of Mining Engineering in the following year. Davis worked for Nathaniel Shaler as a field assi ...

Cycle Of Erosion
The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain. Landscapes that show evidence of more than one cycle of erosion are termed "polycyclical". The cycle of erosion and some of its associated concepts have, despite their popularity, been a subject of much criticism. Description William Morris Davis, the originator of the model, divided it into stages whose transition is gradual. The model begins with an uplifted or to-be-uplifted landscape. Then Davis defined a ''youthful'' stage where river incision is the dominant process shaping the landscape. During the ''youthful'' stage height, differences between uplands and valley bottoms increase rapidly. The ''youthful'' stage is followed by a ''mature'' stage in which height differences between valley bottoms and uplands are at t ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Norwegian Journal Of Geography
__NOTOC__ ''Norwegian Journal of Geography'' ( no, Norsk Geografisk Tidsskrift) is a peer-reviewed scientific journal published by Routledge on behalf of the Norwegian Geographical Society. It covers geographical topics of interest to Norwegian researchers giving equal weight to human and natural geography. It was established in 1926 as successor of the ''Norsk Geografisk Aarbog'' ("Norwegian Geographical Yearbook"), which was published from 1889 to 1921. The editor-in-chief at one point was Kerstin Potthoff of University of Bergen. In 2012, Michael Jones was the editor, and he had started in 2006. He was based at the Norwegian University of Science and Technology, in Trondheim. He announced that as of 2012 the journal would change from publishing four issues per year to five, and that the number of editors had increased to four. He stated:As before, the journal publishes articles on themes related to the geography of Norway, the other Nordic countries and adjacent regions, inc ...

Nathaniel Shaler
Nathaniel Southgate Shaler (February 20, 1841 – April 10, 1906) was an American paleontologist and geologist who wrote extensively on the theological and scientific implications of the theory of evolution. Biography Born to a slave-holding family in Kentucky in 1841, Shaler studied at Harvard College's Lawrence Scientific School under Louis Agassiz. After graduating in 1862, Shaler went on to become a Harvard fixture in his own right, as lecturer (1868), professor of paleontology for two decades (1869–1888) and as professor of geology for nearly two more (1888–1906). Beginning in 1891, he was dean of the Lawrence School. Shaler was appointed director of the Kentucky Geological Survey in 1873, and devoted a part of each year until 1880 to that work. In 1884 he was appointed geologist to the U.S. Geological Survey in charge of the Atlantic division. He was commissioner of agriculture for Massachusetts at different times, and was president of the Geological Society of America in ...

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Louisiana Purchase
The Louisiana Purchase (french: Vente de la Louisiane, translation=Sale of Louisiana) was the acquisition of the territory of Louisiana by the United States from the French First Republic in 1803. In return for fifteen million dollars, or approximately eighteen dollars per square mile, the United States nominally acquired a total of in Middle America. However, France only controlled a small fraction of this area, most of which was inhabited by Native Americans; effectively, for the majority of the area, the United States bought the "preemptive" right to obtain "Indian" lands by treaty or by conquest, to the exclusion of other colonial powers. The Kingdom of France had controlled the Louisiana territory from 1699 until it was ceded to Spain in 1762. In 1800, Napoleon, the First Consul of the French Republic, regained ownership of Louisiana as part of a broader effort to re-establish a French colonial empire in North America. However, France's failure to suppress a revol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josiah Dwight Whitney
Josiah Dwight Whitney (November 23, 1819 – August 18, 1896) was an American geologist, professor of geology at Harvard University (from 1865), and chief of the California Geological Survey (1860–1874). Through his travels and studies in the principal mining regions of the United States, Whitney became the foremost authority of his day on the economic geology of the U.S. Mount Whitney, the highest point in the contiguous 48 United States, and the Whitney Glacier, the first confirmed glacier in the United States, on Mount Shasta, were both named after him by members of the Survey. Early years Whitney was born November 23, 1819, in Northampton, Massachusetts, the oldest of 12 children. His father was Josiah Dwight Whitney (1786–1869) of the New England Dwight family. His mother was Sarah Williston (1800–1833). He was the brother of grammarian and lexicographer William Dwight Whitney (1827–1894).

Lucretia Mott
Lucretia Mott (''née'' Coffin; January 3, 1793 – November 11, 1880) was an American Quaker, abolitionist, women's rights activist, and social reformer. She had formed the idea of reforming the position of women in society when she was amongst the women excluded from the World Anti-Slavery Convention held in London in 1840. In 1848 she was invited by Jane Hunt to a meeting that led to the first public gathering about women's rights, the Seneca Falls Convention, during which Mott co-wrote the Declaration of Sentiments. Her speaking abilities made her an important abolitionist, feminist, and reformer; she had been a Quaker preacher early in her adulthood. When the United States outlawed slavery in 1865, she advocated giving former slaves, both male and female, the right to vote (suffrage). She remained a central figure in reform movements until her death in 1880. The area around her long-time residence in Cheltenham Township is now known as La Mott, in her honor. Early life ...

Quaker
Quakers are people who belong to a historically Protestant Christian set of Christian denomination, denominations known formally as the Religious Society of Friends. Members of these movements ("theFriends") are generally united by a belief in each human's ability to experience Inward light, the light within or see "that of God in every one". Some profess a priesthood of all believers inspired by the First Epistle of Peter. They include those with evangelicalism, evangelical, Holiness movement, holiness, Mainline Protestant, liberal, and Conservative Friends, traditional Quaker understandings of Christianity. There are also Nontheist Quakers, whose spiritual practice does not rely on the existence of God. To differing extents, the Friends avoid creeds and Hierarchical structure, hierarchical structures. In 2017, there were an estimated 377,557 adult Quakers, 49% of them in Africa. Some 89% of Quakers worldwide belong to ''evangelical'' and ''programmed'' branches that hold ...

Meteorologist
A meteorologist is a scientist who studies and works in the field of meteorology aiming to understand or predict Earth's atmospheric phenomena including the weather. Those who study meteorological phenomena are meteorologists in research, while those using mathematical models and knowledge to prepare daily weather forecasts are called ''weather forecasters'' or ''operational meteorologists''. Meteorologists work in government agencies, private consulting and research services, industrial enterprises, utilities, radio and television stations, and in education. They are not to be confused with weather presenters, who present the weather forecast in the media and range in training from journalists having just minimal training in meteorology to full fledged meteorologists. Description Meteorologists study the Earth's atmosphere and its interactions with the Earth's surface, the oceans and the biosphere. Their knowledge of applied mathematics and physics allows them to understand the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geomorphology
Geomorphology (from Ancient Greek: , ', "earth"; , ', "form"; and , ', "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
