Regarding coherentism, can an individual have multiple webs of belief or is it only one web?

Here's the crux of my question: Is the idea that within one giant web are topics such as, physics, math, religion, etc and one will be justified in believing something as long as none of these conflict?

1. Does an individual have one (** and only one**) giant web of beliefs?

2. Does an individual have multiple webs i.e.(one for math, physics, religion, etc)?

3. If there are multiple webs, how does one rectify the possibility of one web intersecting with another web?
