What is the particle size of silt in millimeters?

Explanation:
Silt is classified by its particle size, which is crucial for understanding its behavior in soil mechanics and engineering. The particle size of silt ranges from 0.002 millimeters to 0.075 millimeters. This size range is significant because it differentiates silt from other soil types like clay and sand. Understanding the particle sizes is essential for various applications, including soil classification and understanding drainage, compaction, and erosion properties. Silt particles are too small to be seen individually with the naked eye but are larger than clay particles, impacting their physical and chemical properties. The other options suggest sizes that either exceed the upper limit or are outside the defined range for silt, leading to confusion with different soil classifications, such as sand or clay. This precise classification helps in soil testing and ensures accurate communication about soil properties in engineering and environmental contexts.
