Four Climates on One Tanzanian Mountain
Kilimanjaro is the tallest mountain in Africa. It rises from the grassy plains of Tanzania, close to the equator. You might expect a place so near the equator to be hot all over. Yet the very top of the mountain is covered with ice.
The reason is height. The higher you climb, the colder the air becomes. Because of this, Kilimanjaro has different zones, a little like the layers of a cake. At the bottom, farmers grow crops such as bananas and coffee in warm, rich soil. Above the farms lies a rainforest, where it is wet and green and monkeys swing through the trees.
Higher still, the trees grow short and the land turns into open moorland dotted with small shrubs. Past that, the ground is dry, rocky, and nearly empty of plants. The last zone is the cold summit, where ice sits on the peak.
A climber who walks up the mountain passes through every one of these zones. It is a bit like traveling from a hot country to a freezing one in only a few days.
