WebAug 27, 2024 · High elevations, such as the mountaintops in the tropical regions, are currently and will continue to be important climate refugia, whereas some lower elevation and latitude populations are at risk of extirpation, particularly for cold-tolerant plants in the tropics and subtropics (Fig. 3 b, c). The lowest altitude of alpine climate varies dramatically by latitude. If alpine climate is defined by the tree line, then it occurs as low as 650 metres (2,130 ft) at 68°N in Sweden, while on Mount Kilimanjaro in Africa, the tree line is at 3,950 metres (12,960 ft).

As winds rise up the windward side of a mountain range, the air cools and precipitation falls. On the other side of the range, the leeward side, the air is dry, and it sinks. So there is very little precipitation on the ... WebA mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock.
