• Icefield — A technical neologism and geographical term borrowed from the English language (icefield), used in glaciology to denote a massive ice field or a vast, continuous expanse of interconnected glaciers covering a mountainous area or a high plateau. Structurally, this glacial mass accumulated over millennia is topographically bounded by mountain ridges piercing through it as nunataks, functioning as a vital hydrological reserve and as an extremely sensitive microscopic indicator in monitoring global climate changes.
• Albâia — The name of a watercourse (Albâia River) or a micro-geographical and hydrographic region located in the Romanian Carpathian or peri-Carpathian space. Capitalized, the proper noun individualizes a specific hydronymic element, structurally integrated into local river basins and recognized in regional topography.
• Albeci — The name of a locality (Albeci village) or a small watercourse; also, historically recorded as a surname of Romanian origin. Capitalized, the proper noun individualizes a specific geographical entity integrated into the local toponymic network or a native genealogical lineage.
• Arpașu Mare — The primary upper watercourse within the Arpaș hydrographic basin, situated on the northern slope of the Făgăraș Mountains, collecting mountain torrents and feeding the hydrographic network of southern Transylvania. The valley carved by this river is characterized by a prominent glacial and rocky terrain, holding major ecological importance due to its faunal biodiversity and local hydropower potential.
• Arroyo — A geographical term of Hispanic origin utilized internationally to designate the dry, deep, and steep bed of a stream or torrent located in an arid or semi-arid region, which rapidly floods with water only after short, violent rainstorms. The phenomenon is characteristic of desert or steppe landscapes, frequently causing flash floods and intense linear soil erosion.
• Avalanche — A large mass of snow, ice, rocks, or earth that suddenly detaches from the steep slope of a mountain and moves rapidly downward, destroying everything in its path; (figuratively) a sudden, massive, and overwhelming accumulation of events, letters, requests, or emotional states.
• Azonal — Not distributed in regular geographic or climatic zones; refers especially to soils (azonal soils) or vegetation formations whose occurrence, evolution, and spatial distribution are exclusively determined by local geological, hydrological, or topographic conditions (such as river alluvium), independent of the macroclimate of that respective latitudinal zone.
