What Are the Two Main Ways of Deposition in Geology?
Discover the two primary types of deposition: mechanical deposition and chemical deposition, and how they form sediment layers.

Deposition occurs in two main ways: mechanical deposition and chemical deposition. Mechanical deposition involves the physical settling of particles from a suspension, such as silt and sand settling in a river delta. Chemical deposition involves dissolved minerals precipitating out of solution, forming layers of sediment, like salt crystals forming in evaporating seawater.
FAQs & Answers
- What is mechanical deposition? Mechanical deposition is the process where particles physically settle out of a suspension, like sand and silt settling in a river delta.
- How does chemical deposition occur? Chemical deposition happens when dissolved minerals precipitate out of solution, forming sediment layers such as salt crystals in evaporating seawater.
- What is the difference between mechanical and chemical deposition? Mechanical deposition involves physical settling of solid particles, while chemical deposition involves minerals precipitating out of a dissolved state.
