Snow has a structure made up of tiny crystals loosely bonded together. These crystals are arranged irregularly, leaving many empty spaces filled with air. Ice, on the...
High temperatures can greatly accelerate plant growth. At first glance, this seems nice, but it actually leaves them less time to accumulate nutrients, ultimately reducing...
The Earth's magnetic field is somewhat like a giant magnet tilted slightly at the center of the planet, with two poles, north and south. But...
When it's hot, the heat strongly promotes the evaporation of water. The water contained in the thin film of soap bubbles evaporates much faster in...
At night, the ionosphere (an electrically charged layer located at high altitude) changes its structure. It becomes more stable and reflects certain radio frequencies better. During the...
Fog is simply water vapor present in the air that turns back into liquid when it comes into contact with a cold surface, like a...
The sun emits radiation that carries thermal energy. When these rays hit a puddle of water, they increase the agitation of the molecules on the...
In winter, several viruses, including those of the flu and the cold, survive longer in cold, dry air, making their spread more efficient. The cool...
Heatwaves often create imbalances in the electrical grid. When electricity demand surges due to intensive use of air conditioning, the grid is put under significant...
That somewhat oppressive sensation of heaviness before a storm mainly comes from the hot, humid, and still air surrounding us. In fact, our body regulates...
