Permafrost: What is it and why is it so important?

Permafrost is like a giant, frozen cake that has been sitting under the ground for thousands of years.

Permafrost is soil, rock, or sediment that stays frozen all year round, just like ice in your freezer. It’s been frozen for so long that it acts like a sleepy giant underneath our feet. In places like Siberia and Alaska, permafrost has been sleeping for thousands of years.

Imagine you have a big cookie jar full of cookies, and you leave it outside in the sun. Eventually, the cookies will melt, just like permafrost can start to melt when it gets warmer. When that happens, things that were frozen for a long time, like old plants or even ancient animals, can come back to life.

Also, when permafrost melts, it can cause the ground to sink or crack, making roads and buildings wobbly, just like how your cookie jar might collapse if the cookies melt too much!

So, permafrost is important because it helps keep our planet cool and stable, like a giant freezer working hard beneath our feet.
