n: the first cross-country pipeline with a 24-inch (61-centimetre) diameter. The 1,340-mile (2,157 -kilometre) Big Inch was begun in 1942 with government financing as a part of an emergency construction program (War Emergency Pipelines) to meet the demand for petroleum products during World War II.

n: a tropical cyclone in Mexico. core n: 1. a cylindrical sample taken from a formation for geological analysis. 2. the metallic, partly solid, and partly molten interior of the earth, about 4,400 miles (7,084 kilometres) in diameter. 3. the central, axial member of a wire rope around which the strands are laid. v: to obtain a solid, cylindrical formation sample for analysis. See radiator core.

n: the outer layer of the earth, varying in thickness from 50 to 30 miles (10 to 50 kilometres). It is composed chiefly of oxygen, silicon, and aluminum.

the outermost crust of the earth.

n: a group of silicate minerals that includes a wide variety of potassium, sodium, and aluminium silicates. Feldspar makes up about 60 percent of the outer 9.3 miles (15 kilometres) of the earths crust.

a silicate mineral, often modified and sometimes part of the movable particles in a formation.

n: (km) a metric unit of length equal to 1,000 metres. One kilometre equals .62 miles.

n: a unit of speed equal to I nautical mile (1.852 kilometres or about I y, statute miles) per hour.

n: the hot, plastic part of the earth that lies between the core and the crust. It begins 5 to 30 miles (10 to 50 kilometres) beneath the surface and extends to 1,800 miles (2,900 kilometres).

n: The intermediate layer of the Earth beneath the crust that is about 2900 km thick [1820 miles] and overlies the core of the Earth. The mantle consists of dense igneous rocks like pyroxenite and dunite, composed of the minerals pyroxene and olivine. The cr

the middle layer of the earth, laying just below the crust and composed of relatively high density rock.

n: (OCS) the land seaward from areas subject to state mineral ownership to a depth of roughly 8,000 feet (2,500 metres),beyond which mineral exploration and development are not, at present, feasible. Boundaries of the OCS are set by law. For example, Louisiana owns 3 miles (4.8 kilometres) seaward from the shoreline. In general, the term is used to describe federally controlled areas.

n: the method of measuring land adopted by the United States in 1785. Under this system, land is measured in squares called congressional townships, which are approximately 6 miles (9.6 kilometres) wide and approximately 6 miles long. The squares are marked off by means of parallel north-south lines called township lines and parallel east-west lines called range lines.

n: 1. a unit of land measurement in the rectangular survey system. Each 6-mile (9.7-kilometre) square, or township, is divided into 36 sections. A section usually is 1 square mile (2,590 square kilometres),or 640 acres (256 hectares). It may be larger or smaller, depending on its position in the township. 2. vertically arrayed data.
