Ice jacking

Ice jacking is what happens when water freezes and turns into ice. When water turns into ice, it expands and takes up more space than it did when it was water. This expansion can cause a lot of pressure on anything that's in the way of the ice.

For example, if ice forms on a lake or a river, it can push against the shore, the sides of a boat dock or a boat. This pressure can be very strong and can cause the shore, dock or the boat to crack or break.

So, imagine you're playing with building blocks and you stack them up as high as you can. When you try to add more blocks, the tower becomes too unstable and falls apart. This is similar to ice jacking - the ice is trying to expand but it has nowhere to go, so it pushes against whatever is in its way until it breaks.

So, the next time you see ice on a lake or river, remember that it's not just frozen water – it's also very powerful and can cause a lot of damage if it's not treated with care.
