Our planet acts like a giant magnet due to the movements of the earth's core composed mainly of molten iron and nickel. This immense ball...
When a volcano erupts, it hurls tons of gases into the air, primarily sulfur dioxide (SO₂), but also carbon dioxide (CO₂), water vapor, and other...
The surface of our planet is divided into huge pieces, called tectonic plates, which float on a semi-fluid layer. These plates are constantly moving, slowly...
The different colors of ash ejected by volcanoes often come from the minerals contained within. For example, a good amount of iron or magnesium gives...
When an earthquake or an underwater landslide releases a huge amount of energy, the water all around moves suddenly, creating giant waves. Offshore, these waves...
When rainwater seeps through the soil, it absorbs carbon dioxide, making it slightly acidic. This carbonic acid-rich water slowly penetrates the cracks in limestone rocks. Over time,...
Rocks that resemble animals are not intentionally shaped by nature. It all starts with classic geological processes, such as sedimentation, the cooling of volcanic lava, or underground...
