When visiting Tanzania, Marcus joined a tour group on a hike up Mt. Kilimanjaro. When he began his hike, Marcus was hot, though dressed in shorts and a T-shirt. After reaching the top, Marcus was cold and noticed snow on the ground. What knowledge would have helped Marcus better prepare for his hike?
1. Mountains that formed from past glaciers tend to have cold climates.
2. The precipitation forecast predicts the day's temperature in mountainous regions.
3. High elevations, even those near the equator, tend to have cooler climates.
4. Soil damaged by poor crop rotation turns cold due to the lack of nutrients.
