Florence Bascom
Florence Bascom (July 14, 1862 – June 18, 1945) was an American pioneer for women as a geologist and educator. Bascom became an anomaly in the 19th century when she earned two bachelor's degrees. Earning a Bachelor of Arts in 1882, and a Bachelor of Science in 1884 both at the University of Wisconsin. Shortly after, in 1887, Bascom earned her master's degree in geology at the University of Wisconsin. Bascom was the second woman to earn her PhD in geology in the United States, in 1893. Receiving her PhD from Johns Hopkins University, this made her the first woman to earn a degree at the institution. After earning her doctorate in geology, in 1896 Bascom became the first woman to work for the United States Geological Survey as well as being one of the first women to earn a master's degree in geology. Bascom was known for her innovative findings in this field, and led the next generation of female geologists. Geologists consider Bascom to be the "first woman geologist in America". ...

John Bascom
John Bascom (May 1, 1827October 2, 1911) was an American professor, college president and writer. Life He was born on May 1, 1827 in Genoa, New York, and was a graduate of Williams College with the class of 1849. He graduated from the Andover Theological Seminary in 1855. Aside from the degrees he received in those places, he held many other scholarly and honorary degrees. He was professor of rhetoric at Williams College from 1855 to 1874, and was president of the University of Wisconsin from 1874 to 1887. He retired in 1903 and died in Williamstown, Massachusetts, on October 2, 1911. He was the author of some thirty or forty books. He said in his biography the books cost him more money than he ever received from their publication. But he also included that he was glad to have written them and is only sorry that he could not have been of more service to his fellow men. He greatly influenced Senator Robert M. La Follette, Sr. during the latter's time at the University of Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kappa Kappa Gamma
Kappa Kappa Gamma (), also known simply as Kappa or KKG, is a collegiate sorority founded at Monmouth College in Monmouth, Illinois, United States. It has a membership of more than 260,000 women, with 140 collegiate chapters in the United States and Canada and 307 alumnae associations worldwide. The main archive URL iThe Baird's Manual Online Archive homepage It is sometimes referred to by its original designation, a "women's fraternity", as it was founded before the term "sorority" was coined. It is a founding member of the National Panhellenic Conference (NPC), an umbrella organization that includes 26 American sororities. History In 1869, two Monmouth College students, Mary Louise Bennett and Hannah Jeannette Boyd, were dissatisfied with the fact that, while men enjoyed membership in fraternities, women had few equivalent organizations for companionship, support, and advancement, and were instead limited to literary societies. Bennett and Boyd decided to create a women's frate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocrystalline
Crystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In an ideal gas, the relative positions of the atoms or molecules are completely random. Amorphous materials, such as liquids and glasses, represent an intermediate case, having order over short distances (a few atomic or molecular spacings) but not over longer distances. Many materials, such as glass-ceramics and some polymers, can be prepared in such a way as to produce a mixture of crystalline and amorphous regions. In such cases, crystallinity is usually specified as a percentage of the volume of the material that is crystalline. Even within materials that are completely crystalline, however, the degree of structural perfection can vary. For instance, most metallic alloys are crystalline, but they usually comprise many independent cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Mountain (Maryland And Pennsylvania)
South Mountain is the northern extension of the Blue Ridge Mountain range in Maryland and Pennsylvania. From the Potomac River near Knoxville, Maryland in the south to Dillsburg, Pennsylvania in York County, Pennsylvania in the north, the range separates the Hagerstown and Cumberland valleys from the Piedmont regions of the two states. The Appalachian National Scenic Trail follows the crest of the mountain through Maryland and a portion of Pennsylvania. Geography South Mountain begins at the Potomac River as a low, narrow ridge, barely one mile wide and only above sea level at its crest. South of the Potomac River in Virginia, the ridge continues as Short Hill Mountain for about before subsiding near the town of Hillsboro. South Mountain in Maryland gradually grows higher and wider towards the north. Near the Pennsylvania border, the mountain merges with the hills of the parallel Catoctin Mountain range to the east and becomes more like a low mountain range than a single cre ...

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Rockford University
Rockford University is a private university in Rockford, Illinois. It was founded in 1847 as Rockford Female Seminary and changed its name to Rockford College in 1892, and to Rockford University in 2013. History Rockford Female Seminary was founded in 1847 as the sister college of Beloit College, which had been founded the year before. The seminary's initial campus was on the east side of the Rock River, south of downtown Rockford. Anna Peck Sill served as principal for the first 35 years. In 1890, the seminary's trustees voted to offer a full college curriculum, which led to the name changing to Rockford College in 1892. Men were first granted admission to the university at the beginning of the 1955–1956 school year. At about this time, the school requested that the City of Rockford close parts of a street adjoining the campus. In January 2008, Dr. Robert L. Head was named the university's seventeenth president, effective July 2008. On October 2, 2012, the board of t ... [...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] |
