"North" is one of the four cardinal directions, typically represented at the top of maps. It is opposite to south and is often associated with colder climates, especially in the Northern Hemisphere. The North Pole, located at the Earth's axis, is the northernmost point on the planet. In navigation, "north" is crucial for determining direction. Compasses point towards magnetic north, helping travelers find their way. Many cultures have used the position of the North Star (Polaris) for navigation, as it remains relatively fixed in the sky, indicating true north for those in the Northern Hemisphere.
