Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary depositional agents?Wind, water (fluvial, lacustrine, marine, glacial), and gravity
2. What is deposition in geology?Deposition is when sediments, soil, or rocks are added to a landform because the moving water, wind, or ice slows down and can no longer carry them.
3. Why does deposition happen when water slows down?When the water's speed drops below a critical level, the particles lose energy and settle, forming layers.

Clastic Sediments: Sedimentary material composed of broken pieces of pre-existing rocks and minerals.
Chemical Precipitation: The formation of solid mineral particles from a solution, often due to evaporation or changes in chemical conditions.
Biogenic Deposition: The accumulation of organic material, such as the shells and skeletons of organisms.
