The only thing that can be directly observed is a galaxy's apparent size (angular size). Since galaxies come in different sizes, this can only give a rough idea of the galaxy's distance from Earth.
Because the size of a galaxy and its distance from Earth are completely unrelated.

"IF Earth's magnetic north pole is not located at the geographic north pole why is a compass useful for determining direction?"
because all the stars in a cluster are about the same age and distance from the Earth
Density is responsible for determining how Earth materials separate out into interior layers.
The time-distance graph of seismic waves shows the relationship between the time it takes for seismic waves to travel and the distance they travel. It helps in determining the speed at which seismic waves propagate through the Earth's interior and provides information about the structure and composition of the Earth's layers.

they are useful by showing where the fossil is buried then on that certain layer, it will be studied to know the age.
People on Earth call it the Milky Way (in English).
Globe

The distance between and the mass of the two bodies are the main determining factors. Their masses and how far apart they are
In addition to correctly determining the size of the Earth and finding correct methods for determining the size of the Moon and the distance to the Moon and Sun, he was the head of the largest library in the western world (Alexandria in northern Egypt) and must have had many students.
