The climatic factors which affect a biome are greatly influenced by:
Latitude
Altitude
Latitude : Latitude plays a key role in determining a biome's climate. The closer a biome is to the equator, the warmer and more humid it will be. Biomes near the poles will be colder and drier.
Altitude : Altitude also affects a biome's climate, as the higher the altitude, the colder and drier the climate will be. This is because the air becomes thinner at higher altitudes, which results in less insulation and less moisture.
It's worth noting that, type of soil, people, and plants also play a role in determining the characteristics of a biome, but they mainly affect the type of vegetation and animals found in the biome. For example, certain types of soil are better suited for certain types of plants, which in turn can support certain types of animals. Human activities such as deforestation, hunting or pollution can have a significant impact on a biome.
