How do biomes change with latitude?
Generally speaking, biomes at higher latitudes are cooler and drier.
Biomes are determined primarily by temperature and precipitation. Generally speaking, biomes at higher latitudes (further away from the equator) are cooler and drier. Closer to the equator, biomes are generally warmer and wetter, as warmer air holds more moisture than colder air.
Biomes above 30 degrees north include temperate deciduous forests, boreal forests, and temperate grasslands. Between the Tropic of Cancer and the equator biomes include tropical rainforest, savanna, and desert.
