To/On/In the north

[Terminat]

I am wondering what's the difference between those sentences. Is every sentence correct?
The town is to the north
The town is on the north
The town is in the north.
Could somebody explain the difference to me?

 

[jutfrank]

to the north means relative to another location. For example,
Newtown is to the north [of Oldtown.]

in the north means relative to the area which contains it. For example,
Newtown is in the north [of the county.]

on the north is not correct unless followed by something. For example,
Newtown is on the north side [of the river.]

Another question, if I would like to point a direction, should I say:
Go to the north
or
Go towards the north

 

[emsr2d2]

Go north.
