Imagine a world where vast regions of Earth are covered in thick ice sheets, stretching for millions of square kilometers. The temperature remains sub-zero for thousands to millions of years, transforming entire landscapes. This is what we call an Ice Age—a time when global climate shifts dramatically, leading to widespread glaciation. But the story of…
The Glacial Cycle of Erosion, proposed by W.M. Davis, follows the same logic as his Normal Cycle of Erosion, where landscapes evolve in sequential stages over time. However, due to the limited availability of glacial topography, this theory was widely criticized and rejected by many geomorphologists. Still, this model provides a broad framework for understanding…
Imagine a mighty glacier descending from towering mountains, its icy surface gleaming under the sun. As it moves downward, it reaches a point where temperatures rise above freezing—the snow line. Here, the glacier begins to melt, and a network of small, rushing streams emerges from its snout (the glacier’s endpoint). This melting process is called…
Imagine you are in a vast, icy landscape where a glacier is retreating after centuries of slow movement. As it melts, it leaves behind a chaotic mix of rocks, sand, and silt—like a construction site abandoned by nature. This is glacial deposition, a process where glaciers, after eroding landscapes, act as transporters and depositors of…
Imagine you are standing in the middle of a massive glacier—an endless river of ice stretching as far as the eye can see. At first glance, it seems calm and motionless. But don’t be deceived! Beneath this seemingly frozen world, a slow yet powerful force is at work, reshaping the landscape. Glacial erosion occurs due…
