It sounds like you're looking for sentences or paragraphs using the provided keywords related to weathering, erosion, and deposition. Here's a passage incorporating those terms:
"Weathering is the gradual breakdown of rocks into smaller particles and minerals. This natural process occurs through various agents, such as wind and water. When rocks break down, they undergo erosion, where agents like water and wind move the sediments from one place to another. Rivers, with their powerful flow, are significant agents of erosion. In fact, water is the fastest agent of weathering and erosion. Over time, as water carries sediments downstream, it shapes the landscape, creating landforms like valleys and deltas.
Erosion, however, is not the end of the story. The journey of sediments doesn't stop with erosion. The process of deposition comes into play, where sediments are dropped in a new location. Deltas, for example, are landforms created by the deposition of sediments at the end of rivers. These areas become hubs for diverse ecosystems as the deposited sediments contribute to fertile soil.
Observing hills, valleys, and other landforms gives us clues about the powerful processes at work. The presence of broken rocks signals weathering, while the movement of sediments indicates erosion. Finally, the deposition of these sediments, often found at the end of rivers, completes the cycle and shapes the ever-changing face of the Earth."
