When the snowflakes descend toward us, their light structure of ice crystals traps a lot of air. As a result, they fall gently, without friction...
When water begins to freeze, the molecules slow down and group together into an ordered structure called a crystalline lattice. This occurs as soon as...
Diamonds do not form on the surface, but are created at great depths, about 150 to 200 kilometers below our feet. At that depth, the...
Originally, fish fins primarily serve to swim, stabilize their bodies, and navigate underwater. However, in some species, these fins have gradually changed, evolving into true...
Water makes up about 60 to 70% of the human body and is the very foundation of the cells of all living organisms. It directly...
Imagine a slightly tilted spinning top: that's exactly what our planet does all year round. The Earth indeed rotates around an axis tilted at about...
When sunlight meets a drop of water, it penetrates inside and refracts, meaning it slightly changes direction upon entering. Inside the drop, this light continues...
The Earth's crust is a solid superficial layer that covers the entire planet, somewhat like a relatively thin eggshell compared to the rest of the...
When sea turtles leave their nest, they largely rely on ocean currents to find their way in the ocean. Like true aquatic highways, these currents...
The Earth is far from homogeneous: it resembles a giant puzzle made up of large blocks called tectonic plates. These plates move slowly, about a...
