Geographical features are natural formations on the Earth's surface that include landforms, bodies of water, and ecosystems. Examples of landforms are mountains, valleys, and plains, while bodies of water include rivers, lakes, and oceans. These features shape the environment and influence climate, weather patterns, and human activities. Ecosystems, such as forests, deserts, and wetlands, are also considered geographical features. They support diverse plant and animal life and play a crucial role in maintaining ecological balance. Understanding these features helps scientists and researchers study the Earth's processes and the impact of human activities on the environment.
