What is one effect of weathering on landforms?

Weathering plays a critical role in shaping the Earth's surface by breaking down rocks and minerals into smaller particles through various processes such as physical, chemical, and biological action. This process actively alters the shape, size, and texture of landforms over time. For instance, physical weathering can create fissures and fractures in rocks, leading to changes in form, while chemical weathering can lead to the dissolution of minerals, affecting the land's composition. As these materials are broken down, they can accumulate and contribute to soil formation, significantly influencing the landscape.

The impact of weathering is evident in features like valleys, cliffs, and sediment deposits that form through the gradual disintegration of larger geological structures, thus transforming the terrain. Thus, the correct answer outlines how weathering modifies landforms rather than just focusing on an increase or decrease in the size of geographical features.
