Answer:
Sediments eroded from mountainsides and shifted through streams are example of conservation of matter.
Step-by-step explanation:
Sediments are the soil resources that are out of their place. Due to the process of transport, detachment, deposition of soil particles by the forces of wind, rain, wind-shear, floods over the soil surface, sedimentation takes place.
This alters density, volume, and area but helps to conserve matter. These sediments travel until the water and wind energy are insufficient to continue the movement. So, the matter will be utilized along with the minerals it carries which makes the soil fertile.
