The United States is home to two of the most iconic mountain ranges in the world—the Rocky Mountains and the Appalachian Mountains. Each range tells a different story, shaped by vastly different geological forces, climates, and human histories. Together, they…
Long before the continents settled into their familiar positions on the map, Earth looked nothing like it does today. Roughly 335 million years ago, nearly all of the planet’s landmasses were fused into a single, colossal supercontinent known as Pangaea.…
Ancient mountains are among Earth’s most enduring geological features, shaped over hundreds of millions of years by tectonic forces, erosion, and deep-time processes. Studying them reveals how continents have moved, collided, and transformed—offering a window into the planet’s dynamic past…
Mountains are among the most enduring features of the Earth’s surface—yet even the tallest peaks are locked in a constant process of transformation. The forces of weathering and erosion work relentlessly, grain by grain, reshaping mountain landscapes across geological timescales.…
Mountain regions cover roughly 27% of the Earth’s land surface and are home to approximately 1.1 billion people worldwide. From the Himalayas to the Andes, and from the Alps to the Ethiopian Highlands, mountain communities have developed remarkable ways of…
Mountain environments are among the most geodynamically active landscapes on Earth, shaped by forces that simultaneously build and destroy terrain. From avalanches and rockfalls to glacial lake outbursts and landslides, mountain hazards pose serious risks to communities, infrastructure, and ecosystems—risks…
