Caves, thanks to a stable climate and constant darkness, provide ideal conditions for preserving these ancient paintings. The moderate humidity and the absence of direct...
The speed of glaciers depends quite a bit on what is beneath the ice. When a glacier slides over smooth rock or wet mud, it...
Arctic glaciers are very sensitive to changes in the climate. Even a tiny warming is enough to trigger accelerated melting. These enormous masses of ice...
Icelandic volcanoes pose a real threat to the local population and even to other European countries. The main risk comes from volcanic ash, which can...
When you climb to higher altitudes, atmospheric pressure decreases: there is less air and its molecules expand more. This expansion leads to a drop in...
Mountains are formed when two tectonic plates collide and push against each other, causing the rock to fold or lift to create impressive reliefs. However, right from...
Inside the caves, the humidity and temperature remain surprisingly stable throughout the year, creating an ideal climate for preserving paintings for thousands of years. Not...
The Moon does not have an atmosphere like the one we know on Earth. As a result, it lacks that natural shield which, for us, burns up...
Beneath the Hawaiian archipelago, there is what we call a hotspot, a kind of deep chimney that rises directly from the mantle, far below the...
