| geothermal energy (An energy produced by tapping the earth's internal heat. At present, the only available technologies to do this are those that extract heat from hydrothermal convection systems, where water or steam transfer the heat from the deeper part of the earth to the areas where the energy can be tapped. The amount of pollutants found in geothermal vary from area to area but may contain arsenic, boron, selenium, lead, cadmium, and fluorides. They also may contain hydrogen sulphide, mercury, ammonia, radon, carbon dioxide, and methane) | الطاقة الحرارية الأرضية | |
| germ (1. A pathogenic micro-organism. 2. Living substance capable of developing into an organ, part, or organism as a whole; a primordium) | جرثومة - بذرة | |
| germ plasm (The hereditary material transmitted to the offspring via the gametes) | البلازما الجرثومية | |
| germination (The beginning or the process of development of a spore or seed) | الإنبات | |
| GHG | غازات الاحتباس الحراري | |
| GIS digital format (The digital form of data collected by remote sensing) | الصيغة الرقمية للبيانات ذات المرجعية الجغرافية | |
| GIS digital system (An organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information that can be drawn from different sources, both statistical and mapped) | نظام البيانات ذات المرجعية الجغرافية الرقمي | |
| GIS digital technique (The transformation to digital form of data collected by remote sensing, traditional field and documentary methods and of existing historical data such as paper maps, charts, and publications) | تقنية البيانات ذات المرجعية الجغرافية الرقمية | |
| GIS laboratory (A laboratory where GIS data drawn from different sources are stored, handled, analyzed and updated) | معمل بيانات ذات مرجعية جغرافية | |
| glacier (Slow moving masses of ice which have accumulated either on mountains or in polar regions. They are found where warm, moist air or warm water meets cold air or water. They move, influenced by the force of gravity and the pressure of the ice, above the underlying slush layers and slide downhill, eventually melting at lower levels to form rivers or reaching sea-level, where they form ice shelves or fall into the water as icebergs) | نهر جليدي | |
| glaciology (1. The study of all aspects of snow and ice; the science that treats quantitatively the whole range of processes associated with all forms of solid existing water. 2. The study of existing glaciers and ice sheets, and of their physical properties) | علم الجليد - الجلاسيولوجيا | |
| glass industry (Industry for the production of glassware) | صناعة الزجاج | |
| glaze (A coating of ice, generally clear and smooth but usually containing some air pockets, formed on exposed objects by the freezing of a film of supercooled water deposited by rain, drizzle, or fog, or possibly condensed from supercooled water vapour) | جليد زلق | |
| global agro-ecological zone | منطقة زراعية ايكولوجية عالمية | |
| global aspect (Aspects concerning the whole world considered as being closely connected by modern telecommunications and as being interdependent economically, socially and politically) | ملمح كوكبي (عالمي) - جانب كوكبي | |
| global convention (A worldwide assembly of national, political party or organizational delegates, or the pact or the agreement that arises from such an assembly that forms, often, the preliminary to an international treaty) | اجتماع عالمي - اتفاقية عالمية | |
| Global Environment Facility (An international organization established in 1990 to provide practical assistance to governments in achieving environmental improvements. The GEF is managed by the World Bank, which contributes 2/3 of its funds, the remaining 1/3 being controlled by the United Nations Development Programme) | مرفق بيئة عالمي | |
| global model (Models concerning different aspects of reality which can be applied at global level) | نموذج عالمي | |
| global warming (Changes in the surface-air temperature, referred to as the global temperature, brought about by the greenhouse effect which is induced by emission of greenhouse gases into the air) | ارتفاع حرارة الأرض | |
| glossary (An alphabetical list of terms concerned with a particular subject, field or area of usage that includes accompanying definitions) | مسرد |
