The correct answer focuses on processes that gradually alter the landscape over time, specifically weathering, erosion, and deposition. Weathering refers to the breaking down of rocks and minerals at the Earth's surface due to factors like temperature changes, water, and chemical reactions. This process is crucial as it prepares materials for transport.

Erosion occurs when weathered materials are moved from one location to another, often by wind, water, or ice. This movement changes the physical landscape, leading to the creation of features like valleys and riverbanks. Finally, deposition involves the settling of these eroded materials in new locations, which gradually builds up landforms such as deltas or alluvial plains.

Together, these processes contribute to slow land changes as they work in tandem over long periods, contrasting with other choices that involve more immediate or human-induced alterations to the land. Urban development and farming, for example, result in rapid changes and direct impacts on land use and ecosystems, while deforestation and irrigation primarily pertain to land use management rather than natural geological processes.
