Geologist: Educational Requirements for Entering the Field of Geology Geologist: Educational Requirements for Entering the Field of Geology A branch of geosciences, geology is the study of the materials that compose the Earth's crust. Geologists analyze rocks, formations and other structures in order to understand how the Earth has changed and evolved over time.

How Diamond-Studded Magma Rises From Earth's Depths Richard A. Lovett According to a new study, diamonds can be carried up through the lithosphere—the crust and uppermost layer of the mantle—by dense magmas rich in carbonate. "These melts are really quite special, because they can hold a huge amount of dissolved carbon dioxide, up to 40 to 45 percent by weight," said study leader James "Kelly" Russell , a petrologist from the University of British Columbia in Vancouver. (Related: "Weird Form of Carbon Acts as 'Reversible' Diamond—A First." ) Previous models had suggested that gases in the magma would increase its buoyancy, helping to push the diamond-laden melt closer to the surface without destroying the precious gems.

Teachers on the Leading Edge is a professional development program for Pacific Northwest teachers of Earth Science. This program features plate tectonics and geologic hazards of the Pacific Northwest. Through funding from the National Science Foundation, Teachers on the Leading Edge has provided teacher workshops each summer from 2008 through 2010. This website offers K-12 teachers an introduction to the active continental margin geology of the Pacific Northwest.

Tauro: Esmeralda. Es la piedra de la tranquilidad y cambiará de color según tu estado de ánimo. Tradicionalmente se la ha relacionado con el amor.Los romanos la consideraron fortalecedora de la visión y predictora del futuro. También los mongoles la utilizaban como talismán y, entre las virtudes más generalizadas a través de los tiempos, se les ha atribuido el poder de dotar de elocuencia, memoria e inteligencia.

Geologic Time: Age of the Earth So far scientists have not found a way to determine the exact age of the Earth directly from Earth rocks because Earth's oldest rocks have been recycled and destroyed by the process of plate tectonics. If there are any of Earth's primordial rocks left in their original state, they have not yet been found. Nevertheless, scientists have been able to determine the probable age of the Solar System and to calculate an age for the Earth by assuming that the Earth and the rest of the solid bodies in the Solar System formed at the same time and are, therefore, of the same age.
