Once upon a time, Aqua the Waterdrop lived in a big, beautiful ocean.
Aqua loved swimming and playing with all the sea creatures.
One day, Aqua decided to go on an exciting adventure to learn about hydrology.
Aqua sailed to a magical waterfall where water fell from high cliffs.
The water was so powerful that it created a river that flowed and flowed.
Aqua followed the river and discovered a beautiful lake with calm, still water.
In the lake, Aqua met a wise old turtle who told Aqua all about hydrology.
Hydrology is the study of water and how it moves on Earth, the turtle explained.
Aqua thanked the turtle and continued exploring the world of hydrology.
Aqua learned that water is always moving, just like life's adventures.
