Geo tag (in the context of GIS) Process of adding geographical identification
mechanism
GHG (greenhouse gas) Gases that have capability to absorb and emit heat
Global warming Rise in the average global temperature
Glacier lake outburst flood (GLOF) Flooding due to the outburst of a glacier lake
Gravitational force The gravitational force is the force of attraction between two
objects with mass
Green building Structures that are resource-efficient and environment-friendly
throughout a building’s life-cycle
Green fuel Also called as biofuel. It is the fuel whose energy is obtained by a process of biological carbon fixation
Greenhouse effect The rise in temperature similar to poly house/glass house used
for growing plants wherein the heat is retained. The phenomenon where in the
absorption of infrared radiation by the GHGs in atmosphere rises temperature of
the earth.
Green technology Applied science to preserve the natural resources and
environment
Green waste All types of organic yard and landscaping waste
Greenhouse gas (GHG) Gases capable of absorbing solar heat
Groundwater recharge Process of adding external water to ground
Groundwater Water present in the spaces between soil particles and between rock
surfaces
Global Warming Potential (GWP) Ratio of warming of atmosphere of the gases
to that caused by same mass of CO 2
Gynaecology (gynecology) Field of study concerned with the health of the female
reproductive systems as well as the breasts
Gyres Circular ocean current
Habitat Locality where an organism or population naturally occurs
Haemodynamics Dynamics of blood flow
Hail storm Type of storm characterized by hail as the prevailing part of its
precipitation
Halocarbons Group of halogenated organic compounds
Hazard Threatening event within a given time period/area
Health outcome Health condition observed in a population or an individual
Heat capacity Ratio of heat absorbed by a substance to the change in temperature
Heat Flow of thermal energy
Heat island An urban area with ambient temperatures more than that of the surrounding non-urban area
Heat of fusion Amount of heat necessary to melt a substance at its normal melting
temperature
Heat of vaporization Heat necessary to evaporate the substance at its normal boiling point
Heat wave Prolonged period of extremely hot weather relative to normal climate
patterns in a given region
Heavy metals Metallic elements having high atomic weights
