Natural features are physical characteristics of the Earth’s surface that occur without human intervention. These include mountains, rivers, lakes, forests, and valleys. Each of these features plays a vital role in the ecosystem, providing habitats for wildlife and influencing weather patterns. Natural features can also shape human activities and cultures. For example, rivers often serve as sources of water and transportation, while mountains can act as barriers that influence settlement patterns. Understanding these features helps us appreciate the complexity of our planet and the interconnectedness of its systems.
