Karst topography is a unique geographical landform shaped by the solubility of carbonate rocks like limestone or dolomite. On a Karst Plain, surface water is scarce because the drainage is primarily subterranean. Over time, the chemical dissolution of the rock creates circular depressions called sinkholes. Rivers often flow into these depressions and continue their course through vast underground cavern systems. These plains are geographically challenging for human settlement due to the lack of surface water and the risk of ground collapse, but they are critical for groundwater storage and are often sites of spectacular natural beauty and tourism.

Mountains are a dominant feature of the Earth’s lithosphere, covering about 26% of its total land area. Geographically, these regions are essential as “water towers,” providing fresh water to nearly half of humanity. Their presence influences global climate by acting as barriers to wind and moisture, leading to orographic rainfall. While they cover a substantial area, mountains are often sparsely populated due to rugged terrain and harsh climates. Understanding this percentage is crucial for environmental planning, as these regions are highly sensitive to climate change and human-induced land degradation, impacting the ecosystem services they provide.

In the classification of relief features, mountains are categorized as Second-order landforms. This hierarchy is based on the scale and origin of the feature. First-order relief includes the massive structural units of the Earth: the continents and the ocean basins. Second-order landforms, like mounRead more
In the classification of relief features, mountains are categorized as Second-order landforms. This hierarchy is based on the scale and origin of the feature. First-order relief includes the massive structural units of the Earth: the continents and the ocean basins. Second-order landforms, like mountains and plateaus, are created by endogenic (internal) forces such as folding, faulting and volcanic activity occurring on the crust. These are the large-scale “constructional” features of our planet. Finally, Third-order landforms are smaller, “destructional” features like valleys, canyons and cirques, which are carved into the second-order forms by exogenic (external) erosional processes.

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.
