Its axis of rotation.
The geographical North and South Pole - not the magnetic poles.
the axis is a imaginary line that cuts trough the earth it points southwest and northeast
rotation of earth -earth is at a tilt so sometimes some parts get more sun then others rotation around the sun -earth will be at different distances from the sun as it rotates around
Earth has four main motions: rotation, which causes day and night; revolution, which causes the annual seasons; precession, which causes a slow wobble in its axis; and nutation, which causes a slight variation in the tilt of its axis.
The inclination of the Earth's axis is important because it causes the change of seasons as the Earth orbits around the sun. This tilt is responsible for the variations in the amount of sunlight different parts of the Earth receive throughout the year, influencing temperature and weather patterns. It also plays a role in driving ocean currents and shaping climate patterns on a global scale.
Dens are unique to the axis.

dogs usually align themselves with the north/south axis and how this is dogs have sensitive chemicals which allows them to sense the earths axis
