Approximately what percentage of the world’s crops and food items are grown in plains? (A) 85% (B) 95% (C) 65% (D) 70%
Plains are the world’s primary "food factories," accounting for about 95% of global crop production. Geographically, plains offer the ideal environment for farming: flat land prevents soil erosion from runoff, allows for efficient irrigation and facilitates the use of modern agricultural machinery.Read more
Plains are the world’s primary “food factories,” accounting for about 95% of global crop production. Geographically, plains offer the ideal environment for farming: flat land prevents soil erosion from runoff, allows for efficient irrigation and facilitates the use of modern agricultural machinery. River-deposited alluvial plains, like the Nile or the Mississippi, are particularly fertile due to the constant renewal of nutrients. Because of this extreme agricultural productivity, plains have become the most critical geographical zones for global food security, supporting the energy needs of the nearly eight billion people on Earth.

Geographically, humans are "plain-dwelling" creatures, with 90% of the population concentrated on just 41% of the land. Plains provide the lowest resistance to human movement and construction.

Geographically, humans are “plain-dwelling” creatures, with 90% of the population concentrated on just 41% of the land. Plains provide the lowest resistance to human movement and construction. Whether it is the Yangtze, the Ganges or the Rhine, river plains have historically served as the magnets for human settlement. This concentration is even more pronounced in modern times, as plains facilitate the massive transportation and communication networks required for globalized trade. However, this high population density also makes plain regions the most vulnerable to hazards like flooding and rising sea levels, posing a significant challenge for future geography.

In human geography, plains are recognized as the 'cradle of civilization' because they provided the surplus food necessary for the birth of cities and states. The flat, fertile land of river valleys allowed for the development of irrigation and high-yield agriculture. This led to a division of laborRead more
In human geography, plains are recognized as the ‘cradle of civilization’ because they provided the surplus food necessary for the birth of cities and states. The flat, fertile land of river valleys allowed for the development of irrigation and high-yield agriculture. This led to a division of labor, where not everyone had to be a farmer, allowing for the rise of scholars, soldiers and artisans. From the Yellow River in China to the Indus in South Asia, plains have been the foundational stages upon which the most significant chapters of human history have been written, proving that geography is a primary driver of cultural evolution.

Block mountains are created by faulting rather than folding. When the crust is subjected to tension, it fractures. A Graben represents the depressed segment that sinks relative to the surrounding land. Geographically, Grabens often form long, narrow valleys with steep walls. A famous example is theRead more
Block mountains are created by faulting rather than folding. When the crust is subjected to tension, it fractures. A Graben represents the depressed segment that sinks relative to the surrounding land. Geographically, Grabens often form long, narrow valleys with steep walls. A famous example is the East African Rift Valley or the Rhine Graben in Europe. The adjacent elevated blocks that remain standing are known as Horsts. This structural “basin and range” topography is a key study area in geomorphology, illustrating how internal Earth forces can physically pull the lithosphere apart to create lowlands.

Geographical classification of mountains is a frequent exam topic. The Vosges mountains are structurally block mountains formed by faulting and crustal uplift associated with rifting in Western Europe. They are the twin of the Black Forest range.

Geographical classification of mountains is a frequent exam topic. The Vosges mountains are structurally block mountains formed by faulting and crustal uplift associated with rifting in Western Europe. They are the twin of the Black Forest range. Fold mountains, like the Alps, are formed by the buckling of crustal layers, which is not the case for the Vosges. Statement A is correct (Sierra Nevada is a massive block), B is correct (Monadnock is the namesake for isolated residual hills) and C is correct (Kilimanjaro is Africa’s most famous volcanic peak). Therefore, pair D is the incorrect match.
