  1. Geology
    Geology (from Greek: γη, [G]e, "earth"; and λόγος, logos, "speech" lit. to talk about the earth) is the science and study of the solid matter that constitutes the Earth. Encompassing such things as rocks, soil, and gemstones, geology studies the composition, structure, physical properties, history, and the processes that shape Earth's components. It is one of the Earth sciences. Geologists have established the age of the Earth at about 4.6 billion (4.6x109) years, and have determined that the Earth's lithosphere, which includes the crust, is fragmented into tectonic plates that move over a rheic upper mantle (asthenosphere) via processes that are collectively referred to as plate tectonics. Geologists help locate and manage the Earth's natural resources, such as petroleum and coal, as well as metals such as iron, copper, and uranium. Additional economic interests include gemstones and many minerals such as asbestos, perlite, mica, phosphates, zeolites, clay, pumice, quartz, and silica, as well as elements such as sulfur, chlorine, and helium.
  2. Volcanoes
    Volcanoes are mountains with a vent from which molten material from deep within the earth can spew under the appropriate conditions. Volcanoes have existed for geologic eons, but many are no longer active. The number of volcanoes worldwide that earth scientists consider active—those that can erupt—was about five hundred in the mid-1990s. Volcanoes are usually located at the junction of the earth's lithospheric plates. In the United States most active volcanoes are located in Alaska or in Hawaii, which consists of a group of islands formed by earlier volcanic eruptions. The West Coast of the continental United States ... has a relatively inactive volcanic zone.
  3. Geology -- Geology Department
    The Department of Physics, Physical Sciences, and Geology offers undergraduate curricula leading to the Bachelor of Science Degree in Geology. A minor in Geology and courses for students seeking a teaching credential in the sciences ... are offered. The Bachelor of Science program consists of required courses plus electives to meet the needs of students who are preparing for employment in geology and for admission to graduate study in geology. Most of the department's courses take advantage of the close proximity of CSU, Stanislaus to the varied and often spectacular geology of the Sierras and coast ranges.
  4. Geology -- Environmental Geology
    Geology is the study of the earth, earth materials, and earth systems. It is a physical and natural science and is characterized by both resource and environmental facets. Industrial employment for geological graduates is broad, emphasizing areas such as energy resources, mineral deposits, and complex environmental issues. Because geology draws heavily on basic science and mathematics, for this program, the core curriculum of basic geology is combined with physics, chemistry, and mathematics.
  5. Geology -- Earth Sciences
    Geology is an interdisciplinary subject that overlaps and depends on other scientific disciplines. Physical geology is concerned primarily with the Earth's materials (minerals, rocks, soils, water, ice, and so forth) and the processes of their origin and alteration. Chemistry and physics are the two scientific disciplines most closely related—study of the chemistry of the Earth's materials is geochemistry, and study of the physical properties of the Earth is geophysics. See ... Geochemistry; Geophysics; Structural geology.
  6. Volcanoes -- Mountains
    Volcanoes are mountains that come in various shapes and sizes, some towering tens of thousands of feet high and others just small domes that rise about 100 feet. Unlike other mountains, though, these natural wonders can erupt with powerful and potentially lethal force.
  7. Volcanoes -- Lavas
    Over the last 2 million years, volcanoes have been depositing lava, tephra, and ash in particular areas of the globe (Figure 2). These areas occur at hot spots, rift zones, and along plate boundaries where tectonic subduction is taking place.
  8. Volcano (Locality)
    The highlight of Volcano's events will be the launch of the s5i IVUS imaging system. While IVUS use has historically required moving a portable console into the lab, the Volcano s5i integrates IVUS directly into the lab through a series of coordinated components. The s5i allows for a high level of customization. The individual components required to run IVUS effectively can be placed in a number of different configurations.
  9. Volcanoes -- World
    Hawai'i Volcanoes National Park, established in 1916, is Hawai'i's most visited attraction. The 333,086-acre park reveals steam vents, lava flows, summits and rift zones of two of the world's most active volcanoes, Kîlauea and Maunaloa. Extending from sea level to 13,677 feet, it ... provides habitat to rare and endangered plant, bird, bat and sea turtle species.
  10. Cascade Range -- Volcanos
    South Sister volcano in Oregon’s Cascade Range is beginning to show signs of awakening after several thousand years of slumber. Although indications are that an eruption is not likely to occur anytime soon, scientists are increasing their vigilance of the volcano, located approximately 22 from miles from Bend, Oregon.
