Definition of deposition in science

The settling of particles or sediment onto a surface. The particles may originate from a vapor, solution, a suspension, or a mixture.

Wikipedia say, "Deposition is the geological process in which sediments, soil and rocks are added to a land form or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment" Hopefully this helps:) Plze mark me brainiest!

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
