Difference between 広まるand 広がる

[Torao92]

as the title suggests I’m not quite sure what the difference is. thanks in advance

[広まる means to propagate, spread like a rumor. 広がる means to spread out, fill an area.

[Torao92]

so 広まるcan be used when something spreads without any restrictions where 広がる is used when there are limits or boundaries right?

[jprspereira]

To paraphrase, 広がる describes something spreading out naturally, like a scenic view or a wildfire, whereas 広まる describes something spreading as the result of an intentional attempt to spread it.

What are the differences between 広める and 広げる and between 広まる and 広がる?

[Pep95]

So if I put a blob of peanut butter on a sandwich and spread it out with a knife, it would be 広まる, but if instead of using the knife I would watch it slowly spread over the sandwich by means of gravity in the span of a couple of hours, it would be 広がる?
