Biomes are large regions that share similar climatic, physical, and biotic characteristics.
Seasonal patterns in sun exposure, latitudinal patterns in air movement, and various factors affecting rainfall lead to a great diversity of local climates (long-term, wide-range weather patterns). As a result, many types of biomes exist worldwide. A biome is a large ecosystem defined by climatic, physical, and biotic characteristics. Biomes can be grouped into terrestrial (land) biomes and aquatic (water) biomes.
