The volcanic ashes from Vesuvius were made up of tiny fragments of volcanic rocks and volcanic glass, initially very light but quickly accumulating to form...
Shells are abundant on some beaches due to various factors. One of the main factors contributing to the abundant presence of shells is the marine...
Rock formations sometimes take on human-like appearances due to a slow and natural process: erosion. Over the centuries, water, wind, and temperature changes gradually wear...
Volcanoes generally form as a result of the accumulation of volcanic materials emitted by successive eruptions. This mainly occurs at the boundaries of tectonic plates, where magma...
In rocks, atoms are naturally organized into precise geometric shapes called crystalline structures. It is these regular patterns that allow crystals to play with sunlight. When a...
Geological formations in the form of arcs are often the result of complex geological processes. One of the mechanisms commonly involved is plate tectonics, where...
Sedimentation is simply the gradual deposition of particles like sand, mud, or shells at the bottom of a lake, sea, or river. Over time, these...
Some minerals have the curious ability to absorb invisible light (such as ultraviolet rays) and reemit it in the form of visible light. This phenomenon...
Granite is primarily composed of three minerals: quartz, feldspar, and mica. The quartz, which is very hard, gives granite a high resistance to wear and...
The Earth's surface is divided into large puzzle pieces called tectonic plates. These plates move slowly but constantly (only a few centimeters per year) due...
