45th parallel north

Okay kiddo, so imagine you have a big ball, like a playground ball, and you drew a line around the middle of it with a marker. That's kind of what the Earth looks like, except it's a lot bigger and the line is called the Equator.

Now imagine you drew another line around the Earth, about halfway between the Equator and the North Pole. That's the 45th parallel north! It's a circle around the Earth that goes through places like Detroit, Michigan, and Bordeaux, France.

People use this line to help them navigate and figure out where they are on a map. They also use it to help figure out things like climate and weather patterns in different parts of the world.

So basically, the 45th parallel north is just a line that goes around the Earth, kind of like the Equator, but it's closer to the North Pole.
