In the Pacific, the seafloor on one side of the youngest crust gets very old, but the seafloor on the other side is much younger. How do you think the location of the youngest aged seafloor in the Pacific Ocean contributes to a more complicated age pattern in the ocean (hint: think about the distance of the youngest seafloor from the nearest continents on both sides of the ocean)?

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
