What is difference between prepositions in and on ?
Cornwall is in the south-east of England.
The Partridge Tree English School is near Norwich on the east coast of England.
Thanks for help.
in the south-east of England
means within the south-east region, surrounded by the border of the south-east region.
on the east coast
generally means next to the water, a coast doesn't really have an area, otherwise you might say
in the costal region
