Approximately 10% of the world’s population lives in mountainous regions. Despite mountains covering over a quarter of the land, the population density is low due to steep slopes, limited arable land and transportation difficulties. However, billions of people living downstream depend directly on mountain resources, particularly for fresh water, minerals and timber. ANSWER: (B) 10%

While mountains cover 26% of the Earth’s land, they are home to only about 10% of the global population. This low percentage reflects the geographical challenges of mountain living, including restricted agricultural space, isolation and susceptibility to natural hazards like landslides. Most mountain dwellers reside in plateaus or valleys within these ranges. Despite this small resident population, mountains have a massive “geographical footprint.” They provide essential resources—water, hydroelectric power and biodiversity—to the billions of people living in the plains below. Consequently, the sustainable management of mountain environments is a critical global priority.
