A geologic hazard is an extreme natural events in the crust of the earth that pose a threat to life and property, for example, earthquakes, volcanic eruptions, tsunamis (tidal waves) and landslides

Geometric depreciation is a depreciation profile based on a constant annual rate of capital consumption over the life of the asset

Geometric depreciation is a depreciation profile based on the efficiency and rentals on a fixed asset declining at a constant geometric rate from period to period

A price index defined as the weighted geometric average of the current to base period price relatives using the value shares of the base period as weights.

A price index defined as the weighted geometric average of the current to base period price relatives using the value shares of the current period as weights.

For a continuous distribution with frequency function f (x) the geometric mean may be defined by the equation: / log G= / logxf(x)dx. /-.

Energy available as heat emitted from within the earth’s crust, usually in the form of hot water or steam. It is exploited at suitable sites:
- for electricity generation using dry steam or high enthalpy brine after flashing;
- directly as heat for district heating, agriculture, etc.

Applicable only to aggregation methods that use either a reference price structure – that is, each country’s quantities are valued by a uniform set of prices - or a reference volume structure – that is, each country’s prices are used to value a uniform set of quantities - to compare countries.

It occurs when lost or abandoned fishing gear stays in the ocean and traps fish or other marine life, indiscriminately killing whatever it catches.

1. British Government bonds.
2. U.S. bonds of AAA standing.

Measure of the deviation of the distribution of income among individuals or households within a country from a perfectly equal distribution. A value of 0 represents absolute equality, a value of 100 absolute inequality.

A mass of land ice which flows downhill under gravity (through internal deformation and/or sliding at the base) and is constrained by internal stress and friction at the base and sides. A glacier is maintained by accumulation of snow at high altitudes, balanced by melting at low altitudes or discharge into the sea.

The glass ceiling is composed of invisible artificial barriers created by attitudinal and organizational prejudices that block women from senior executive management positions.
