What Is a Terrestrial Biome?

Terrestrial biomes are major regions in the Earth that share the same climate despite being in different geographical locations. The Earth has six major land biomes: rainforests, deserts, tundras, grasslands, taiga and temperate deciduous forests. Each biome differs in weather, latitude, topography, relative humidity and amount of sunlight. These climatic regions are determined mainly by rainfall and temperature and are distinguished by their predominant plants and animal communities.
