What is the difference between precipitation and sedimentation?

• Precipitation is the falling of water from the atmosphere, while sedimentation is the settling of particles from a fluid.

• Precipitation is the accumulation of soil particles in a riverbed.

• Sedimentation refers to the formation of clouds in the sky.

• Precipitation is the process of water evaporating into the atmosphere.
