Geography hub
Explore Earth’s physical systems—from mountains and rivers to climate patterns and fragile ecosystems. This hub organizes our best guides to landforms and water, weather and climate, biodiversity, and today’s pressing environmental issues. Start here, then dive into focused subtopics or explore places by continent, country, and city.
This comparison usually comes down to one confusion: both are branches of geography, but they ask different first questions. Human geography starts with people, societies, and spatial patterns…
The Caucasus is one of those mountain regions many readers recognize immediately but place only vaguely. The usual confusion is not just about location; it is also about…
Many readers meet this river under two different names and assume they are looking at two different waterways. They are not. The confusion comes from language, mapping habits,…
Armenia (the modern Republic of Armenia in the South Caucasus) is compact on a world map—about 11,484 square miles (29,743 square kilometers)—but it behaves like a much larger…
Iran is easiest to understand as a high interior “roof” (the Iranian Plateau) with strong edges: mountains that act like walls, deserts that act like sinks, and coastlines…
A doline (also seen as “dolina”) is one of the most recognizable features of karst terrain: a closed depression that pulls water inward and often sends it underground.…
A ventifact is one of the clearest “signatures” of wind erosion: a rock face worn smooth, faceted, or pitted by airborne sand. They’re common in dry, open landscapes…
A deflation hollow is a shallow ground depression formed when wind lifts and carries away loose sediment from the surface (a process called deflation). You’ll see them most…
Glacial erosion landforms are bedrock shapes carved by moving glacier ice. The trick is that ice erodes valley floors and walls at the same time, leaving signatures that…
Water erosion landforms are the shapes made when moving water removes rock or soil and carries it away. Rivers carve valleys and gorges. Storm runoff cuts rills and…
