Small fine particles present in the anther
WebbAn atom is composed of a dense central nucleus made up of protons and neutrons, which is surrounded by an electron cloud. Since the electron cloud is much larger than the … WebbLarger particles (greater than 10 micrometers in diameter) tend to settle to the ground by gravity in a matter of hours whereas the smallest particles (less than 1 micrometer) can stay in the atmosphere for weeks and are mostly removed by precipitation. There are also evidence that it is not uncommon for aerosols to "travel across the ocean".
