Learn how our planet's landscapes, from mountains to hills, plateaus to plains, have been sculpted over millions of years by powerful geological forces.
- The planet's diverse landscape is shaped by a handful of key forces.
- The world's great mountain ranges form at tectonic plate boundaries. As plates collide the force causes Earth's crust to rise.
- Deep gorges and valleys are formed by water erosion.
- Deposition from glacial ice and rivers has also helped create hills, plains and plateaus.
The huge diversity of our planet's landscapes – from towering mountains to valleys and plains – is shaped by just a handful of key forces.
The two most powerful land-forming forces are first in the Earth's inner heat – which moves the Earth's gigantic plates and causes them to collide, dramatically …
