The sentence that describes deposition changing the surface of Earth is:
C. A delta is formed as a river flows into an ocean.
Explanation:
1. Deposition is a geological process where sediment, such as sand, silt, and clay, is deposited or dropped in a new location.
2. When a river flows into an ocean, the sediments it carries are deposited at the mouth of the river.
3. Over time, these deposited sediments accumulate and form a landform known as a delta.
4. Deltas are characterized by their triangular shape and are formed by the deposition of sediments carried by the river.
In contrast, the other options describe different geological processes:
- A river breaking away rocks to form a canyon describes erosion.
- Lava from a volcano cooling to form an island describes volcanic activity.
- A mountain range forming as tectonic plates collide describes the process of mountain building through tectonic forces.
