Geology and Earth Science Terms and Definitions Click a letter below to find the definition of a geological term. A few of our favorite definitions Alluvial Fan A fan-shaped wedge of sediment that typically accumulates on land where a stream emerges from a steep canyon onto a flat area.
In map view it has the shape of an open fan. Alluvial fans typically form in arid or semiarid climates.
Butte A conspicuous hill with steep sides and a flat top. The top is usually a cap-rock of resistant material. This structure is frequently an erosional remnant in an area of flat-lying sedimentary rocks. Coring Bit A hollow cylindrical drill bit used for cutting a cylinder of rock, called a "core," from a well.
The bottom of the bit is made of metal with embedded diamond abrasives for grinding through rocks. As the bit cuts down through the rock, the "core" is contained within the last section of drill pipe.
About every thirty feet, all of the drill pipe and the drill bit are pulled from the well so the core can be lifted to the surface and removed. Coring is very slow and very expensive work.
A geology dictionary that is used regularly is one of the most important tools for developing professional competence. A good dictionary should be on the desk of every geologist and within easy reach.
Density Current A gravity-driven flow of a dense fluid down a slope through a fluid of lower density. They occur on land pyroclastic flows or underwater turbidity currents.
Density currents often occur underwater where the fluids have differences in temperature, salinity, or concentration of suspended particles.

Although many people believe that diamond has the strongest dispersion of all gems, a few gems such as sphaleritedemantoid garnet shown in the photospheneand zircon have an even greater dispersion. Garnet Garnet is the name of a group of silicate minerals that share a common crystal structure, but they vary in composition.NYSED / P / OCAET / OSA / Past Examinations / Science Regents Examinations / Physical Setting/Earth Science / Translated Editions / Spanish Physical .
