Priya built a model of the land. First she made a high plateau out of clay. It was flat on top.
Then she poured water across it again and again. The water slowly cut a deep, narrow canyon.
Where the water reached her pretend ocean, sand and mud piled up in a fan shape. Her grandpa said, “That's a delta!”
