An arch is like a rainbow made of stone. It has a curved shape that helps it stand strong without falling down. Imagine you’re building with blocks, and you make a bridge by putting blocks in a curved shape. The blocks stay up because they lean on each other, just like friends holding hands in a circle.
Another way to think about an arch is like a big smile. When you smile, your lips curve up and stay that way. An arch does the same thing, but it’s made from materials like stone or bricks. This shape is very strong and can hold up heavy things, like the roof of a building or a bridge over a river.
Picture a giant umbrella made of bricks. The umbrella’s handle is the arch’s base, and the top part of the umbrella is the curved part of the arch. This curved part helps spread out the weight, so the arch doesn’t break. It’s a smart way to build things that need to be strong and last a long time.
