Siberia. The “milder” (Da) climates (here the key is the
small a, which denotes a warm summer) are found only in
limited parts of Eurasia. Winters are very cold in all the
(D) climates and downright frigid (and long) in the (Dfb)
and (Dfc) regions. (D) climates are generally continental,
on the interior of continents, instead of on coasts.
Continental locations make (D) climates generally drier
than (C) climates. The continentality of (D) climates also
contributes to the large range of temperatures found
across the year because land heats and cools much faster
than water.
Polar
climates, where tundra and ice prevail, are
found poleward of (D) climates. The polar location of (E)
climates means temperatures are cold throughout the
year. As a result, plant life does not break down and nour-
ish the soil during the year, and also a layer of permafrost
(frozen ground) exists year round.
The World Map of Agriculture
When comparing the world map of agriculture (Fig. 11.18)
with the distribution of climate types across the world
(Fig. 11.17), we can see the correlation between climate
and agriculture. For example, drier lands rely on livestock
ranching, whereas moister climates are marked with grain
