Geological features are natural formations on the Earth's surface created by various geological processes. These include mountains, valleys, rivers, and cliffs, which result from the movement of tectonic plates, erosion, and sedimentation. Each feature tells a story about the Earth's history and the forces that shaped it over millions of years. Common geological features include volcanoes, which erupt molten rock, and canyons, formed by the erosion of rock by water. Other examples are glaciers, which carve out valleys as they move, and sand dunes, shaped by wind. Understanding these features helps scientists learn about the planet's past and predict future changes.
