Stonehenge is primarily constructed with two types of stones: sarsen sandstone and bluestones. The giant sarsen sandstones originate from northern Wiltshire, about 25 km from...
Volcanic ash is primarily composed of mineral particles and rock fragments. It contains silica, often in the form of silicon dioxide, as well as iron...
The Perito Moreno Glacier is immense, with a thickness that sometimes exceeds 700 meters. This enormous mass acts as a natural cold reservoir. When ice...
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...
Sand grains are small fragments of silica, generally quartz. They measure between 0.0625 mm and 2 mm in diameter. The shape of the grains can...
Millions of years ago, monumental geological forces shaped the Norwegian fjords. The Earth's crust bent, cracked, and lifted. These movements, caused by plate tectonics, created...
Mountains form due to the movements of tectonic plates. When two plates crash into each other, it creates folds and faults in the Earth's crust. This process...
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 cover about a quarter of the Earth's surface. They primarily form through tectonic movements where plates collide and push the ground upward. The tallest...
Ivittuut thrived mainly due to its enormous reserve of cryolite, a rather rare and highly sought-after mineral. The great peculiarity of cryolite is that it...
