crystallizing minerals in Washington‚ D.C. in 1928. In order to best express his findings to his scientific brethren‚ Bowen created a visual display based on when and under what conditions each silicate mineral crystallized. This is extremely important to geologists because it helps them to easily understand the order that specific minerals were created. Bowen’s reaction series is broken down into five main parts. First‚ is the Temperature scale ranging between 800 and 1600 degree Celsius. Next‚ the minerals

Global Warming: Origins‚ Effects‚ and Potential Solutions Since the dawn of the 19th century‚ civilization has been very dependent on the consumption of fossil fuels. Greenhouse gases‚ especially carbon dioxide‚ coming from these emissions plague our atmosphere. Greenhouse gases trap heat and prevent warmer air from escaping our atmosphere‚ which causes a containment of excess heat‚ thus causing a climate change; in this case‚ a rise in temperature. There has been large amounts of debate on whom

Broad and flat‚ plains are well named. Some appear when glaciers and streams erode away elevated terrain; others spread where rising magma pushes‚ erupts‚ and spews. Some plains spill into the oceans‚ and others are bound by mountains on several sides. They all hide a tumultuous geologic history beneath their level disguise. The base of the vast Great Plains in North America formed when several small pieces of continental crust collided and welded together more than a billion years ago. As time

“What evidence is there to support Alfred Wegener’s theory of continental drift?" Alfred Wegener‚ born November 1st 1880‚ was a German scientist who took a great interest in meteorology and paleoclimatology and in 1905 graduated from the University of Berlin with a Ph.D. in Astronomy. His most notable work was the theory of continental drift. However his theory was highly controversial at the time as he had little evidence‚ but as technology enhanced neumerous discoveries were made which helped

primary Earth science. The word means "study of the Earth". Geology deals with the composition of Earth materials‚ Earth structures‚ and Earth processes. It is also concerned with the organisms of the planet and how the planet has changed over time. Geologists search for fuels and minerals‚ study natural hazards‚ and work to protect Earth’s environment. Meteorology - The study of the atmosphere and how processes in the atmosphere determine Earth’s weather and climate. Meteorology is a very practical
