Cross over? i have no idea lol
I think the answer is a sorry if I get it wrong
A main sequence star is bigger than a neutron star,because neutron stars are remnant degenerate matter from a collapsed star,they are completely made out of Neutrons and are extremely dense,and have a diameter of only a several Kilometers.M<span>ost of them have a mass of 1.35-2 Solar masses.</span>
Nonpoint source pollution is a greater hazard, because scientists are not able to identify a single location the pollution came from. It is harder to find a solution if they are unable to find the source.
Hope this helps!
have a great day.
