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.

"IF Earth's magnetic north pole is not located at the geographic north pole why is a compass useful for determining direction?"
Why is studying star clusters useful?
because all the stars in a cluster are about the same age and distance from the Earth
What physical property is responsible for determining how Earth materials separate out into interior layers?
Density is responsible for determining how Earth materials separate out into interior layers.
What does the time-distance graph of seismic waves show?
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.

What is the awnser to the universe the galaxys the stars the planets life?
The answer to life, the universe, galaxies, stars, and planets is not definitively known. Many believe in scientific explanations such as the Big Bang theory for the universe's origins and evolution, while others find meaning in philosophical or spiritual beliefs. Ultimately, the search for understanding and meaning is a deeply personal journey that can differ for each individual.
