One of the most important climatic factors is temperature and it generally decreases with increasing latitude (as you go north) and altitude (as you go up).
In fact, scientists have determined that for every 1000 meters that we go up in altitude, there is a decrease in temperature of about 6 ° C.

That is equivalent to increase our latitude a linear distance of 500 to 750 km at the same elevation.

This rule, often called Humboldt's Rule, predicts that the plant communities will transform similarly with changes in temperature and altitude.
