Using articles can be confusing sometimes, so when we say "the North pole" it takes the definite article "the " unlike for example "North America" here "the " is omitted, plz I would like to know why ?
It’s because North America is unique and poles aren’t - each rotating body has two of them.
“The” is used when identifying a specific instance from a collection - hence the North Pole as opposed to the South Pole, or when referring to the collection itself - the Poles.
Because there is only one North America it is always specifically identified and there can’t be a collection of them. There can be the Americas refereeing to the collection of both North and South America, or the countries, geographic features, plants or animals therein. There can also be the North Americas referring to the collection of Canada, the United States of America, and Mexico but such usage is uncommon.
The usage of differentiation can be seen in the following exchange:
“I’m John Adams.”
“Are you the John Adams who was 2nd President of the USA?”
“No, I’m the John Adams who was 6th President of the USA.”
Such a conversation would be implausible about North America because unlike John Adamses, there is only one North America.
