A hill is like a big green bump on the ground. Imagine when you build a sandcastle and you make a small mound of sand; a hill is like that, but much bigger and covered with grass and sometimes trees. People can walk up hills, and it feels like climbing a gentle staircase made by nature.
Think of a hill as a giant pillow that the Earth uses to rest its head. When you stand on top of a hill, you can see things far away, like looking over a big fence. Hills are not as tall as mountains, which are like the giants of the land.
Hills can be friends to animals too. Rabbits and foxes might make their homes in the soft, grassy parts of a hill. They provide a place to play, run, and explore for both animals and children.
In some stories, hills are like secret keepers; they hide treasures or magical places. They make the land look wavy and fun, not flat and boring. Walking on a hill can make you feel like an explorer on an adventure!
