In Los Angeles, the current important process is coastal process. In Fargo, the current importance processes is aeolian processes. In Nome, glacier has begun created since 18000 years ago.
Biomes
Biome is a large terrestrial ecosystem characterized by specific plant communities and formations, usually named after the predominant vegetation in the region. Arctic Tundra (AAT) terrestrial biome occupies the Nome, Alaska area.
