Nullah

Imagine a tiny little stream of water, just a few inches wide, flowing through your backyard. That stream is called a nullah. It's not a big river or even a little stream - it's just a small trickle of water that runs through the ground.

Nullahs are important because they help carry rainwater away, especially in areas where there is a lot of rainfall. They can also help prevent flooding by making sure the water doesn't build up too much in one place. And sometimes, people use nullahs to help irrigate crops or provide water for animals.

So next time you see a little stream or trickle of water, you can call it a nullah!
