The ‘Great Dividing Range’ is located in which continent? (A) Africa (B) South America (C) Australia (D) North America
The Great Dividing Range (or Eastern Highlands) is Australia's most prominent topographical feature. Formed over 300 million years ago, it consists of a complex series of plateaus, mountain ranges and escarpments. Geographically, it is not exceptionally high, but it has a profound impact on AustraliRead more
The Great Dividing Range (or Eastern Highlands) is Australia’s most prominent topographical feature. Formed over 300 million years ago, it consists of a complex series of plateaus, mountain ranges and escarpments. Geographically, it is not exceptionally high, but it has a profound impact on Australia’s climate, trapping moisture from the Tasman Sea to create a fertile coastal strip while leaving the interior “outback” dry. It is a classic example of an Old Fold Mountain system that has been significantly modified by subsequent faulting and millions of years of denudation.

Geographically, a caldera represents a "destructive" volcanic landform. When a massive volume of magma is erupted quickly, the structural support for the mountain top vanishes, causing it to cave inward. This creates a basin much larger than the original vent. Famous examples include the YellowstoneRead more
Geographically, a caldera represents a “destructive” volcanic landform. When a massive volume of magma is erupted quickly, the structural support for the mountain top vanishes, causing it to cave inward. This creates a basin much larger than the original vent. Famous examples include the Yellowstone Caldera and Santorini in Greece. In competitive exams, calderas are distinguished from “Craters” by their size and the specific process of collapse. They are significant in physical geography as indicators of super-volcanic activity and often host unique geothermal features like hot springs and geysers.

The human geography of mountains is defined by "low density but high significance." While only one in ten people lives in these high-altitude zones, mountains provide essential ecosystem services to the rest of humanity.

The human geography of mountains is defined by “low density but high significance.” While only one in ten people lives in these high-altitude zones, mountains provide essential ecosystem services to the rest of humanity. They are the “Water Towers of the World,” supplying freshwater to half of the global population. Life in these regions is often characterized by subsistence farming, pastoralism and tourism. In exams, this statistic highlights the contrast between plains (where 90% reside) and mountains, emphasizing how physical relief fundamentally limits large-scale human settlement and urban infrastructure development.

The Anatolian Plateau is a major structural feature of the Middle East. Geographically, it represents a high-altitude "Median Mass" that was uplifted during the collision of the Arabian and Eurasian plates. The Pontic range runs along the Black Sea coast, while the Taurus range runs along the MediteRead more
The Anatolian Plateau is a major structural feature of the Middle East. Geographically, it represents a high-altitude “Median Mass” that was uplifted during the collision of the Arabian and Eurasian plates. The Pontic range runs along the Black Sea coast, while the Taurus range runs along the Mediterranean. These ranges act as climatic barriers, leaving the central plateau with a semi-arid, continental climate. This configuration is essential for understanding Turkey’s physical geography, as it dictates the country’s agricultural zones and historical settlement patterns in the dry heartland compared to the lush coastal fringes.
See lessWhich of the following is NOT a characteristic of ‘Shield Volcanoes’?
Geomorphology distinguishes shield volcanoes by their "effusive" eruption style. The lava, being low in silica, is very runny (low viscosity). When it erupts, it spreads out in thin layers rather than piling up into a steep cone. Consequently, shield volcanoes, like Mauna Loa in Hawaii, are massiveRead more
Geomorphology distinguishes shield volcanoes by their “effusive” eruption style. The lava, being low in silica, is very runny (low viscosity). When it erupts, it spreads out in thin layers rather than piling up into a steep cone. Consequently, shield volcanoes, like Mauna Loa in Hawaii, are massive in diameter but have very low-angle slopes. This contrast is a frequent exam point: low viscosity leads to broad shields (constructive), while high viscosity leads to steep, explosive strato-cones (destructive). Understanding lava chemistry is key to identifying these different mountain landforms.
