The diagram gives an illustration of temperature changes in tropical and temperate mountains.
In general, tropical mountains contain twice as many zones as temperate ones. Interestingly, although given in different sizes, the former is usually much larger and taller than the latter.
As for tropical mountains, the first 1000 metres represent a warm zone that is suitable for growing tropical crops. It is followed by a temperature zone between 1000 and 1500 altitude that can be used for coffee and cocoa plantations. Above is a cool area where grain can be grown. The forest grows at an altitude of 3000 to 4000 metres, but there is a limit for broad-leaved trees in this region. As for the last two zones, only alpine meadows are located at an altitude of 4000 4500 metres, and there is permanent snow on top of them.
In contrast, a cool zone in temperate mountains extends from the foot to 5,000 feet; it is a good place to plant grains, potatoes, and flax. Forests are less vast; they extend in elevation from 5,000 to 6,000 meters. In addition, the zone has rich alpine meadows, which can survive at an elevation of between 6,000 and 10,000 meters. The highest zone of permanent snow is between 10,000 and 11,000 meters.
