The combination of weathering and erosion leads to the wearing down or denudation of mountains and continents, with the erosion products being deposited in rivers, internal drainage basins, and the oceans. geology (countable and uncountable, plural geologies) The science that studies the structure of the earth (or other planets), together with its origin and development, especially by examination of its rocks. Earthquake seismology has largely been responsible for defining the location of major plate boundaries and of the dip of subduction zones down to depths of about 700 kilometres at those boundaries. Harry Cockburn Ancient rock formations provide new clues about earthquake risks. Geologists study Earth materials: People use Earth materials every day. This is the science of geochronology, which in recent years has revolutionized scientific perception of Earth history and which relies heavily on the measured parent-to-daughter ratio of radiogenic isotopes (see below).

The bizarre plant-like animals that say life’s big bang never happened. Here are some examples: Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. Over the next several years, the number of geology job openings is expected to exceed the number of students graduating from university geology programs. Productspecificaties. Since the 1970s even such distant planetary systems as those of Jupiter, Saturn, and Uranus have been explored by probes. Please select which sections you would like to print: While every effort has been made to follow citation style rules, there may be some discrepancies. The advanced degrees provide a higher level of training, often in a geology specialty area such as paleontology, mineralogy, hydrology, or volcanology. They do similar work to locate and produce oil, natural gas, and groundwater. Geology.

Ring in the new year with a Britannica Membership. In other subdisciplines of geophysics, gravimetric techniques are used to determine the shape and size of underground structures; electrical methods help to locate a variety of mineral deposits that tend to be good conductors of electricity; and paleomagnetism has played the principal role in tracking the drift of continents. Today one of the principal concerns of mineralogy is the chemical analysis of the some 3,000 known minerals that are the chief constituents of the three different rock types: sedimentary (formed by diagenesis of sediments deposited by surface processes); igneous (crystallized from magmas either at depth or at the surface as lavas); and metamorphic (formed by a recrystallization process at temperatures and pressures in the Earth’s crust high enough to destabilize the parent sedimentary or igneous material). Dig deeper into geology by learning about everything from ancient fossils and rock formation, to present-day landslides and earthquakes. Don't be hesitant. The adventures of a geologist: From shipwrecks to mapping the Arctic. The geologist is responsible for the discovery of minerals (such as lead, chromium, nickel, and tin), oil, gas, and coal, which are the main economic resources of the Earth; for the application of knowledge of subsurface structures and geologic conditions to the building industry; and for the prevention of natural hazards or at least providing early warning of their occurrence. Stratigraphers still use the two main principles established by the late 18th-century English engineer and surveyor William Smith, regarded as the father of stratigraphy: (1) that younger beds rest upon older ones and (2) different sedimentary beds contain different and distinctive fossils, enabling beds with similar fossils to be correlated over large distances. This in turn helps in interpreting the mode of formation and the depositional environment of sedimentary rocks. Several disciplines of the geologic sciences have practical benefits for society. Volcanic Hazards Map: Geologists prepared this volcanic hazards map to communicate the location of hazardous areas to citizens, government agencies, and businesses. To prepare a map like this requires an understanding of volcanoes, an ability to recognize volcanic deposits in the field, an ability to prepare a map, and an ability to communicate.

Astrogeology is important in that it contributes to understanding the development of the Earth within the solar system. Unmanned space probes have yielded significant data on the surface features of many of the planets and their satellites. The unconsolidated accumulated sediments are transformed by the process of diagenesis and lithification into sedimentary rocks, thereby completing a full cycle of the transfer of matter from an old continent to a young ocean and ultimately to the formation of new sedimentary rocks.

Joint, in geology, a brittle-fracture surface in rocks along which little or no displacement has occurred. If geologists can prepare maps of areas that have flooded in the past, they can prepare maps of areas that might be flooded in the future. The allied field of geophysics has several subdisciplines, which make use of different instrumental techniques. [ jē-ŏl ′ə-jē ] The scientific study of the origin of the Earth along with its rocks, minerals, land forms, and life forms, and of the processes that have affected them over the course of the Earth's history. The term geology refers, according to Britannica, the fields of study concerned with the solid Earth. geology. Knowledge of the processes of interaction of the atmosphere and the hydrosphere with the surface rocks and soils of the Earth’s crust is important for an understanding not only of the development of landscapes but also (and perhaps more importantly) of the ways in which sediments are created.
