le: Surprising Cold Facts You Didn't Know Winter is here, and as temperatures continue to drop, we all bundle up, turn up the heat, and try to stay warm. But did you know that there are some surprising cold facts that you may not be aware of? Here are a few:
1. Ice is sticky: You may think that ice is slippery, but it's actually quite sticky. Ice sticks to itself so well that it's hard to separate two pieces once they're stuck together. This is why it can be so difficult to remove ice from sidewalks and roads in the winter.
2. The coldest temperature ever recorded on Earth is -12
8.6°F (-8
9.2°C): This temperature was recorded at the Soviet Union's Vostok Station in Antarctica in 198
3. It's so cold that your skin can freeze instantly and your breath can turn to ice.
3. Wind chill can make it feel colder than it actually is: Wind chill is the temperature your body feels when wind is blowing on it, and it can make it feel much colder than the actual temperature. For example, if it's 20°F (-
6.7°C) outside and the wind is blowing at 20 miles per hour, it will feel like it's -5°F (-20.6°C) outside.
4. Some animals can survive in extremely cold temperatures: Animals that live in the Arctic and Antarctic have adapted to the cold and can survive in temperatures that would be deadly to humans. For example, emperor penguins can withstand temperatures as low as -40°F (-40°C) and stay warm by huddling together in large groups.
5. Melting ice can cause sea levels to rise: As the earth's average temperature rises, ice at the poles and glaciers around the world are melting at an alarming rate. This can cause sea levels to rise, which can lead to flooding and other problems for coastal cities and towns.
6. The oldest ice core ever extracted is over 800,000 years old: Ice cores are samples of ice from deep within glaciers that can help scientists understand the earth's climate history. The oldest core ever extracted is over 800,000 years old and has revealed important information about past ice ages and climate shifts.
7. Freezing temperatures can cause physical changes in the body: When exposed to extreme cold, the body can go into "hibernation mode," slowing down its processes to conserve energy. This can cause physical changes like the thickening of blood and a decrease in heart rate. Next time you're braving the cold, remember these surprising cold facts and stay warm!
