Dead of winter? Lakes freeze from the top down. Ice floats, so it insulates the water below.
Fish survive under that icy blanket. They slow down, but they don’t freeze. Lazy, not dead.
If ice sank, oceans would freeze solid. Life on Earth would be a bad joke. Thank water’s weird density for summer swims.
Freezing Is a Time Capsule
Ice cores from Greenland hold air bubbles from 800,000 years ago. That air is older than humans.
Scientists drill them to see ancient climates. It’s like popping open a prehistoric soda can. Fizz from the ice age.
Mammoths found frozen in Siberia still have fur and skin. Frozen for 40,000 years. Perfectly preserved snack? You decide.
