The Brainliest Answer!
Gravity pulls all things toward the center of the earth - as a result, everyone on earth only feels upside down if their head is pointing toward the ground or they are high/drunk on something. North and South are just directions given to indicate the intersection of earth and its axes at the extreme edges of the earth. North is considered "up" simply because more people live in the northern hemisphere and most people like to think that they are "up." In fact, people in the argentina, especially , have maps that we would consider upside-down, where north is down and south is up.

SO , HOPE IT HELPS!!!!!!!!!!!!!
