Temperate grasslands
Deserts
Tundra
The sinking air of the Ferrel and Hadley cells means that there is high pressure - hence the low rainfall (less than 250 mm per year)
Cold air sinks at the poles and rushes back towards the equator - any trees are dwarf species and stunted
Very cold nights because the heat from the day is lost to space under the starry skies; plants need shallow roots to absorb the dew!
Located south of temperate and boreal forests
Very large temperature range - in the 20 °C range in the summer, but perhaps as much as -40 °C in the winter.
Mosses and lichens can just about hang on here
Summers are wetter than winters; occur in the middle of continents so winters are colder than near the sea
If you go far enough north here, the Sun won't get above the horizon in winter - although it won't set during the summer
Very hot during the day - the Sun is strong and skies are cloudless - around 30 °C or hotter but very little rain
It's very hot all year round in these tropics
It's very dry here, but a cold desert; it gets above 0 °C in the summer, but winters are brutal - cold and windy
Other than grasses, a few shrubs are occasionally found
The ground may freeze during the winter, and only the top layer may thaw in the summer (when it turns into a bog with lakes and midges)
