Landforms are natural features on the Earth's surface that shape the landscape. They include mountains, valleys, plateaus, hills, and plains. Each landform is created through various geological processes, such as erosion, sedimentation, and volcanic activity. These processes can take thousands or even millions of years to form distinct landforms. Different landforms can be found in various regions around the world, influenced by climate, tectonic activity, and other environmental factors. For example, the Himalayas are a famous mountain range, while the Great Plains in North America are known for their flat terrain. Understanding landforms helps us appreciate the diversity of our planet's geography.
