Ethics & morals

When my teacher told us about this assignment I thought ethics was ethnics. But later found out it was a totally different that I've never come across this word before.I asked my dad what ethics meant. He explained it to me. But I was still left in the dark confuzzled. I  began to roam the internet .  In search of  ethics and morals. I finally found out what both meant.

Ethics is more of the social rules that is unwritten.
Morals is more of an individual concept.

You could think of it as a ethics are external and morals are internal.
