Five Climates on One Tanzanian Mountain
Mount Kilimanjaro rises in the east African country of Tanzania. It is the tallest mountain in Africa, and it stands alone on a wide plain instead of in a long chain of peaks. It is a volcano that is no longer erupting. What makes it special is that climbing it feels like traveling across the whole world.
The trip begins at the bottom in warm farmland. Farmers there grow crops such as coffee and bananas. Higher up is a rain forest, where the air is wet and the trees are draped in moss. Monkeys and many birds live among the branches.
Next comes a zone of heath and moorland, with shrubs and tall, odd-looking plants. The air is cooler and the clouds often drift past. Above that is a dry, rocky desert where very little can grow and the nights are cold. Finally, at the top, there is a zone of ice and bare stone, where the air is thin and cold.
Temperature drops as the land gets higher. That simple fact creates a ladder of climates, one stacked above another. Scientists study such mountains to learn how plants and animals fit into each kind of place.
