📚 Topic Summary
Erosion is the process where natural forces like wind, water, and ice wear away and transport soil and rock. This process creates various landforms. For example, rivers can carve out valleys, and glaciers can form U-shaped valleys. Understanding erosion helps us appreciate how landscapes change over time.
Landforms are natural features of the Earth's surface, each shaped by different processes, including erosion. Common landforms include mountains, valleys, plains, and coastlines. These features are constantly evolving due to the ongoing effects of erosion and other geological activities.
