What percentage of the total area of the lithosphere is covered by plateaus? (A) 33% (B) 41% (C) 26% (D) 30%
Plateaus are one of the major landforms of the Earth, occupying about 33% of the lithosphere. Geographically, they are elevated landforms that are lower than mountains but higher than the surrounding plains. They are often referred to as "Tablelands" due to their flat summits.

Plateaus are one of the major landforms of the Earth, occupying about 33% of the lithosphere. Geographically, they are elevated landforms that are lower than mountains but higher than the surrounding plains. They are often referred to as “Tablelands” due to their flat summits. Plateaus are formed through various processes, including volcanic eruptions (Lava plateaus) or crustal uplift. Because they cover a third of the land, they are crucial geographical units. Many plateaus, such as the African Plateau, are ancient stable blocks (shields) that contain the world’s richest deposits of gold, diamonds and copper.

In terms of linear extent, the Andes are the world’s largest mountain system. Stretching through seven South American countries, they cover a vast geographical area. Unlike the Himalayas, which are concentrated in a relatively compact arc, the Andes span nearly 60 degrees of latitude. This extreme length creates a diverse range of environments, from tropical glaciers to sub-arctic peaks. Geographically, they are unsurpassed in their continuous longitudinal extent, making them the most significant physical feature of the Western Hemisphere and a dominant influence on the ecology and climate of the entire South American continent.

Only about 9% of the global population resides on plateaus. This relatively low percentage is due to the fact that many plateaus, like the Tibetan or Bolivian Altiplano, have harsh climates or thin soils. However, in tropical regions, plateaus are often preferred over humid lowlands because of theirRead more
Only about 9% of the global population resides on plateaus. This relatively low percentage is due to the fact that many plateaus, like the Tibetan or Bolivian Altiplano, have harsh climates or thin soils. However, in tropical regions, plateaus are often preferred over humid lowlands because of their cooler, healthier climates. Geographically, plateaus are “economic powerhouses.” While they may not support the massive urban populations seen in river plains, they are essential for the global economy, as they contain the majority of the world’s mineral resources, including iron, coal and precious metals.

Plateaus are famous as "mineral storehouses," but they rarely contain mineral oil. Geographically, plateaus like the Canadian Shield or the African Plateau are made of ancient, hard crystalline rocks. Metallic minerals like iron, gold and manganese are abundant in these formations.

Plateaus are famous as “mineral storehouses,” but they rarely contain mineral oil. Geographically, plateaus like the Canadian Shield or the African Plateau are made of ancient, hard crystalline rocks. Metallic minerals like iron, gold and manganese are abundant in these formations. Coal is also found in many plateau regions where sedimentary layers exist. However, mineral oil and natural gas require soft, younger sedimentary basins (like river deltas or shallow seas) for their formation and entrapment. Therefore, while you go to plateaus for mining metals, you typically look to plains and continental shelves for oil and gas reserves.

Geographically, an intermontane plateau is a “plateau between mountains.” These features are created during periods of intense tectonic activity when the crust is folded and uplifted. Because they are encircled by towering peaks, they often experience “rain shadow” effects, leading to arid or semi-arid climates. The Tibetan Plateau and the Bolivian Altiplano are classic examples. These are considered the most complex plateau types because their height is maintained by the same compressive forces that support the surrounding mountains. They are vital for global geography as they influence regional wind patterns and host the headwaters of major rivers.
