Soil can best be described as the
a. third layer beneath the earth's surface.
b. sandy bottom of the ocean's floor.
c. loose covering of weathered rocks and decaying organic matter.
d. layer of bedrock four layers beneath the earth's surface.

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
