14. Plains/Plateaus

  • Plains are flat areas. Plateaus are flat areas too, but they are higher than 200 metres above sea level.

15. Mountains/Depressions

  • Mountains are higher than 600 metres. An example of a mountain is Mount Everest. Depressions are the opposite of mountains. They are depressed areas.
