If the earth
were “flat”, would an observer view Polaris at different altitudes?

If conditions are just right, you can see Polaris from just south of the equator. ... viewing from sea level with a perfectly flat horizon toward the north. And we'll further assume ideal sky conditions that allow our observer ... equator from which the star would scrape the horizon — if Earth had no atmosphere.

Explanation:

not completely sure but i think it’s many moons, smaller in size and a ring system.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
