They are North Pole and South Pole
Two nonmoving objects that are useful reference points are a stationary pole or a fixed building. These objects can serve as points of comparison or markers to determine direction, distance, or positioning.
The prime meridian is to longitude. The prime meridian is the line of reference for measuring east-west positions on the Earth, just as the equator is the reference line for measuring north-south positions.
It is not possible to have a band connecting two points on Earth's surface with zero magnetic variation. Magnetic variation occurs due to differences in Earth's magnetic field at different locations, making it impossible for two points to have identical magnetic properties.
To find the actual distance between two points on Earth using a graphic scale, measure the distance between the two points on the map using the scale provided. Convert this measurement to actual distance by using the ratio scale (e.g., 1 cm = 100 km) provided on the map. Multiply the measured distance by the ratio to find the actual distance between the two points on Earth.
There are any number of such fixed reference points, but in real life the choices are made based on cultural or religious reasons rather than physical ones.Here are a few physical fixed reference points that one might use to base a calendar on.1. The winter solstice2. The summer solstice3. The Earth's perihelion (about January 4)4. The Earth's aphelion (about July 4).Of all the calendars in use on Earth, only one has is defined with any reference to an astronomical event, and it's pretty loosely connected; in the Hebrew calendar, Rosh Hashanah (the Jewish New Year) is at the New Moon closest to the fall equinox.
The two basic points of reference on the surface of the Earth are the North Pole and the South Pole. These points represent the northernmost and southernmost points on Earth's axis of rotation, respectively.

We have several reference points on the Earth's surface, for our convenience. The North and South Poles are a couple. The choice of Greenwich as the zero longitude, and of the International Date Line are another two. These points have no specific feature on the surface, they are decided on for the convenience of the users.

Motion movement and changes
The two points and the centre of the earth define a plane, and the intersection of this plane with the surface of the earth is a circle - the "Great Circle". The shortest distance between the two points is the smaller of the two arcs on this circle.
Two reference temperature points are needed to create a thermometer scale. These points are used to calibrate the scale and typically consist of the freezing and boiling points of a substance, such as water.
The two frames of reference commonly used on Earth are the inertial frame of reference, which is a non-accelerating frame, and the rotating frame of reference, which takes into account the Earth's rotation. Both frames are important in physics for describing motion and dynamics accurately.
