What happens when water inside the tree freezes is like ice forming inside a drinking straw on a cold day.
Imagine you have a big, tall tree, think of it like a giant drinking straw made of wood. Inside this straw, there's water, just like when you sip from your straw and drink juice or water. Now, on a really cold winter day, that water turns into ice, just like the liquid inside your straw turns to ice if you leave it outside in the snow.
Why does the tree care?
When the water turns to ice, it expands, it gets bigger! It's like when you put water in a balloon and freeze it; the balloon stretches because the ice takes up more space. This expansion can cause little cracks inside the tree, just like how a balloon might pop if it stretches too much.
What happens next?
In spring, when the ice turns back to water, it shrinks again, like melting ice in your drink. The tree goes through this cycle every year, and over time, these small cracks can make the tree look a little rougher or even break off in big pieces, just like how a straw might snap if you twist it too much!
Examples
- Imagine a glass of water in the freezer, that's what happens inside trees when they freeze.
- Freezing water inside trees can make them look like they're cracking from the inside.
