North is one of the directions on Earth.

Aristotle defines the directions with the stars but uses them to describe the typical winds that blow from there. In Greece, the north wind comes from continental Europe or Asia. In Egypt, in contrast, the north wind comes across the Mediterranean sea.

Depending on the origin of the wind, it is either dry or humid and either cold or warm.

With regard to the stars, on the northern hemisphere "north" is where the stars are ever visible, their trails are perfect circles and they'll never set below the horizon.

North is also the direction where the sundial points at high noon every day.
