Explain how weathering erosion and deposition happen in our enviroment

Erosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water, glaciers, waves, and wind all cause erosion. Deposition begins when erosion stops; the moving particles fall out of the water or wind and settle on a new surface.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
