I WONDER - How Old Are Icebergs?

Icebergs, formed from compacted snow on glaciers and ice shelves, can be thousands of years old. They provide valuable insights into Earth's climate history through their ice layers, which may contain trapped air bubbles and particles. Scientists analyze these elements to understand past temperatures and atmospheric conditions.
