Why Do Mountains Form in Chains?

Mountains form in chains because Earth’s crust is moving, just like puzzle pieces shifting under your hands.

Imagine you're playing with building blocks. If two sides push toward each other, the blocks stack up, and that's how mountains grow. When big parts of Earth move together, they make long lines of high land, called mountain chains.

Like a Squeezed Sandwich

Think of Earth’s crust like bread in a sandwich. When two pieces of bread (called plates) press against each other, the filling (the ground between them) gets squished up, and poof! A mountain range is born, just like when you squeeze a stack of paper and it folds into hills.

The Pushy Earth

Sometimes, one plate slides under another, like when you push your hand under a blanket. This pushing makes the land above rise, and that’s how chains of mountains keep getting taller and longer, all over the world.

Examples

  1. A mountain range forms when two large pieces of Earth’s crust push against each other, like a wall being squeezed from both sides.
  2. Imagine stacking books and pushing them together, the middle ones get pushed up to form a line of hills.
  3. Mountains in chains are created when continents collide, similar to cars crashing into each other.
