PLEASE HELP!! DUE TONIGHT! 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 that ocean (hint: think about the distance of the youngest seafloor from the nearest continents on both sides of the ocean)?

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
