The mountain range of the Alps is not a recent formation; it emerged about 30 million years ago. At that time, two large tectonic plates, the African...
The stones of Stonehenge are arranged according to a carefully studied geometry, primarily based on circles and arcs. This organization allows the monuments to evenly...
Volcanic ash is essentially a mixture of tiny rock particles and volcanic glass, ejected into the air during an eruption. They are very fine, sometimes...
The Perito Moreno glacier remains stable because it naturally loses a significant portion of its mass through calving, a spectacular phenomenon where huge blocks of...
Glaciers function a bit like a giant thermometer: as soon as the temperature rises, it is immediately visible in their behavior. When it gets warmer, glaciers melt...
The sand grains capable of "singing" share common physical characteristics: they are generally round, well-sorted in size, and their surface is particularly smooth and polished, as if...
Norwegian fjords owe their spectacular appearance to a rather tumultuous geological history. It all begins hundreds of millions of years ago, when tectonic plates collide, pushing and...
Mountains are in perpetual motion, even if it’s not obvious. At the heart of the rocky massif, the layers of snow and ice accumulated exert...
Viscosity is basically the ease with which magma flows or doesn't. A very viscous magma, like a paste, struggles to release the gases within it. This creates...
Mountains act as real barriers, forcing the circulating air to divert, slow down, or rise in altitude. When air encounters a massif, it naturally ascends, cools down...
