Imagine you could shape the Earth with giant hands like play dough. You could push land high into the clouds, or dig deep, winding trenches straight through solid rock.
Every natural shape of the Earth's surface is called a landform. Let's explore four of the most amazing shapes on our planet.

High Ground: Mountains and Hills

A mountain is land that rises super high above the ground around it, usually with steep sides and a sharp, pointy peak at the top.
A mountain range is a long chain or series of connected mountains, such as the Rocky Mountains or the Appalachian Mountains.
A hill also rises above the land, but it is much shorter and has a smooth, rounded top instead of a sharp peak.
Hills are much easier to climb than mountains because their slopes are gentle rather than steep.
If mountains and hills rise up tall toward the sky, what sits down between them?

Lowlands: Valleys

A valley is a low area of flat or gently sloping land found between hills or mountains.
Rivers flowing down from mountain tops slowly carry tiny pieces of sand and dirt away, gradually carving out a valley shaped like the letter V.
