Iceberg

Icebergs are like super-sized ice cubes that have broken off from huge ice sheets on land. To be called an iceberg, it has to be at least as long as 15 school buses parked end-to-end! Most of an iceberg is hiding underwater, like a secret. So, when you see one, you're only seeing a small part of a much bigger icy giant!

These icy travelers start their journey on land as part of massive glaciers or ice shelves. When a piece breaks off, it's called calving. It's like a giant ice cube snapping off a frozen playground slide! Some icebergs are shaped like tables, while others are more bumpy and irregular, depending on where they broke off from.

Icebergs are like giant refrigerators for the ocean! They melt slowly, which helps keep the ocean water cool. This is super important for the fish and other sea creatures that live there. They also carry tiny bits of rock and soil from land, which can help new plants grow when they melt.

Because most of an iceberg is underwater, ships have to be very careful. It's like trying to see a huge rock hidden just below the water's surface. If a ship bumps into an iceberg, it can cause a lot of damage. That's why sailors always watch out for these icy mountains!
