Silt is classified in geology as a fine-grained sediment that consists of particles that are smaller than sand but larger than clay. This means it typically ranges in size from 0.002 to 0.05 millimeters in diameter. It is commonly formed from the weathering and erosion of rocks and can be deposited by water, such as rivers and lakes. The presence of silt in sedimentary environments indicates past conditions such as flooding or quiet water, where finer particles settle out of suspension.

When silt is deposited by water, it contributes to the formation of fertile soils and can affect water retention, creating suitable conditions for plant growth. Silt can be found in various terrestrial and aquatic environments, making it an important component of geological processes and ecosystems.

The other options describe unrelated concepts. The description of a developed ovule refers to a biological term, celestial bodies pertain to astronomy, and the taste experience related to salt falls under the domain of sensory perception. None of these definitions align with the geological characterization of silt.
