Clunch is a kind of material that is often used for building houses and other buildings. It's a mix of chalk, sand, and a special binding substance that holds everything together. You can find clunch in places where there's a lot of chalk and sand, like on the coast of England.
Clunch is a little bit like making a sand castle at the beach. You start by mixing together sand and water to create a kind of gooey mixture. When you add more and more sand, it becomes stronger and stronger. Clunch works the same way, but instead of just plain sand and water, they add chalk and a special binding substance called lime.
Once the clunch is mixed together, builders can use it to make walls, floors, and ceilings. It's a really strong material, so it doesn't break easily. Plus, it's really good at keeping out the cold and wind, so it's great for building houses in places with harsh weather.
Overall, clunch is a really useful material that has been used for hundreds of years to build all kinds of amazing buildings. If you're ever in England, you might even get to see some clunch buildings up close!
