"Frost quakes happen when saturated ground rapidly freezes after a period of mild or above-freezing temperatures," AccuWeather Senior Meteorologist Adam Douty explained. "Since water expands when ...
Temperature vs time plots, showing the Mpemba Effect. The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions.

Fires become even more of a hazard during extreme cold. Water mains may break and water supplies may become unreliable, making firefighting more difficult. The air during a cold wave is typically denser and thus contains more oxygen, so when air that a fire draws in becomes unusually cold it is likely to cause a more intense fire.
During the final stage of freezing, an ice drop develops a pointy tip, which is not observed for most other liquids, and arises because water expands as it freezes. [10] Once the liquid is completely frozen, the sharp tip of the drop attracts water vapor in the air, much like a sharp metal lightning rod attracts electrical charges. [10]
Dodson joined the Seahawks this past summer on a one-year, $4.26 million deal and he shined initially. Dodson led the team with 71 tackles in nine games.
Leidenfrost droplet Demonstration of the Leidenfrost effect Leidenfrost effect of a single drop of water. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.
Donald Trump has hit out at Joe Biden in a furious response to appearing to freeze for more than 30 seconds mid-speech at the National Rifle Association’s (NRA) annual meeting at the weekend.
