How does the length of North America from north to south affect its nature?

North America stretches from north to south for many, many kilometers; this continent is so large that almost all climatic zones, except for the equatorial one, pass through it. That is why nature is very diverse here. In the very north, there is practically no vegetation, everything is covered with ice. Below are the tundras. Further, the tundra passes into the taiga, there is already more vegetation. The variety of trees is greater than in Eurasia! Deciduous forests stretch even lower. The very south of North America has evergreen rainforests, palm trees and a warm climate.
