мир / земля / свет

 мир / земля / свет

It seems Russians use all three of these words to mean Earth or world in some way.

How are they different from one another?

I realize that свет can also be used to mean "light" or "electricity."

 

Also, it seems that земля can simply mean "the ground."

 

I also know that мир can also mean "peace". But I'm mostly interested when these three words are used in the sense of earth/world.

Could somebody create several sentences using all three of these words that highlight their unique connotations? Any further illuminating commentary would also be appreciated. 

 

Thanks!
