Explanation:
Pulsar is also called as<u> neutron stars or white dwarfs.</u> These are formed after the supernova explosion. Their mass is higher than a normal star. And the most different thing we find in pulsar is that, in a pulsar the proton and electrons combine themselves to form a neutron. That's why this is also called as neutron star. After neutron or white dwarf the star goes to the black dwarf stage.
Remember when the core of the iron becomes iron rich that time it cannot sustain further nucleo synthesis process, that's why it goes for a supernova explosion. Which results the formation of neutron star or white dwarf, followed by black dwarf or black hole.
One type of weathering is man made weathering. (For example) Humans may carve a rock or mine for minerals. Another type is natural weathering. This is when a river may push a rock or lighting may scratch a tree. That weathering is naturally occurring. Hope that helped!
