  • Desert - very dry, either hot or cold
  • Tundra - cool, treeless, and dry. The permanently frozen soil layer is called permafrost.
  • Scrub - coastal area with hot, dry summers and mild, cool, rainy winters
  • Taiga or Coniferous Forest - cool and dry, with coniferous trees
  • Temperate Deciduous Forest - cool and rainy, with deciduous trees
  • Grassland - Windy, partly dry sea of grass with few trees, including tropical savanna, prairie, steppe, pampas, etc.
  • Mountain Biomes - there are a lot of different mountainous biomes, from grasslands at low altitudes, taiga (coniferous forests) below the treeline, and alpine (the same as tundra)
  • Temperate Rain Forest - cool and wet
  • Tropical Rain Forest - warm and very wet
  • Wetlands - there are many types of wetlands, including swamps, marshes, moors, bogs, fens, sloughs, etc. These have nutrient rich soil.
