Geologist: Educational Requirements for Entering the Field of Geology

Geologists analyze rocks, formations and other structures in order to understand how the Earth has changed and evolved over time. Continue reading to learn about the educational requirements for entering this field. Education and Degree Options Some geologists working for private industries may only be required to have a bachelor's degree. Specialized positions, such as consulting for companies in the oil industry or professorships in the geosciences, generally require a master's or doctoral degree. Bachelor's Degree Program in Geology Students preparing for a career as a geologist may enroll in a bachelor's degree program in geology, earth sciences or a related scientific field. Graduate Programs in Geology Graduate programs cover concepts in plate tectonics, petrogenesis and other advanced geological topics.

How Diamond-Studded Magma Rises From Earth's Depths

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. The new lab experiments now show how molten carbonate reacts with other chemicals in Earth's lithosphere to release the gas, offering a likely mechanism for speeding up the dense magma.

There, a type of material called kimberlite magma forces its way up from deeper in Earth's mantle, cracking the solid rock. Nature . Instituto Geográfico Nacional. Introduction to Plate Tectonics and Earthquakes - Instructional Aids. Teachers on the Leading Edge is a professional development program for Pacific Northwest teachers of Earth Science.

Introduction to Plate Tectonics and Earthquakes - Instructional Aids

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. Teaching resources provided include animations, video lectures, slide shows, virtual field experiences, and lesson plans that feature plate tectonics and geologic hazards of the Pacific Northwest. Although intended for middle school teachers of Earth Science, most resources can be adapted for use in many K-12 grade levels. 1720 feet-tall - Lituya Bay, Alaska. (As reported by Don J. Miller in United States Geological Survey Professional Paper 354-C, Giant Waves in Lituya Bay, Alaska, 1960) Account of Howard G. Ulrich Mr. Ulrich and his 7-year-old son, on the Edrie, entered Lituya Bay about 8:00 p.m. and anchored in about 5 fathoms of water in a small cove on the south shore.

"The wave definitely started in Gilbert Inlet, just before the end of the quake. Ulrich continued to watch the progress of the wave until it reached his boat about 2 1/2 to 3 minutes after it was first sighted. After the giant wave passed the water surface returned to about normal level, but was very turbulent, with much sloshing back and forth from shore to shore and with steep, sharp waves up to 20 feet high. Account of William A. Mr. and Mrs. The Badger, still at anchor, was lifted up by the wave and carried across La Chaussee Spit, riding stern first just below the crest of the wave, like a surfboard.

Japan's quake updated to magnitude 9.0

Several workers are believed to have been injured in the blast, which seems to have caused major structural damage to the plant. A state of nuclear emergency was declared at the plant yesterday as its operator, the Tokyo Electric Power Company, struggled to contain rising temperatures and pressures in the core of two reactors whose cooling systems failed after Friday's magnitude 9.0 earthquake.

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.

Geologic Time: Age of the Earth

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. The ages of Earth and Moon rocks and of meteorites are measured by the decay of long-lived radioactive isotopes of elements that occur naturally in rocks and minerals and that decay with half lives of 700 million to more than 100 billion years to stable isotopes of other elements. Ancient rocks exceeding 3.5 billion years in age are found on all of Earth's continents. For additional information on this subject, see G.
