Depth, at which natural gas is located, varies from 1,000 meters to several kilometers. The process of gas production meaning its extraction from the subsurface, collection and treatment for transportation starts upon the completion of geological exploration after the deposits have been identified.
2. metric-a decimal unit of measurement of the metric system (based on meters and kilograms and seconds); convert all the measurements to metric units; it is easier to work in metric. metric unit.
Interval scale Quantitative attributes are all measurable on interval scales, as any difference between the levels of an attribute can be multiplied by any real number to exceed or equal another difference. A highly familiar example of interval scale measurement is temperature with the Celsius scale.ariables measured at the interval level are called interval variables or sometimes scaled variables as they have units of measurement. Ratios between numbers on the scale are not meaningful, so operations such as multiplication and division cannot be carried out directly.
