Terrestrial biomes are defined by temperature and precipitation.

  1. Tropical forest thrives in high temperatures and abundant rain.

  2. Desert exists in hot and dry areas.

  3. Savanna is dominated by grass in tropical areas with seasonal rainfall.

  4. Grassland is dominated by grass in temperate areas with seasonal rainfall.

  5. Deciduous forest is dominated by trees in temperate areas; a cold season causes trees to shed leaves.

  6. Chaparral is a savanna-like biome along coastal areas where winter rains support shrubs

  7. Coniferous forest exists in cold areas that receive enough precipitation to support evergreen trees.

  8. Tundra is found in colder areas where the soil below 1 meter is permanently frozen into permafrost, and only short vegetation can grow.

  9. Polar ice is found near the poles with almost no precipitation. Freshwater is scarce; life is limited to coastal areas and its oxygen-rich cold waters.
