While there is no practical limit on what types of people can form a friendship, friends tend to share common backgrounds, occupations, or interests and have similar demographics.
Approximately 800,000,000 humans live in the Southern Hemisphere, representing only 10â12% of the total global human population of 7.3 billion. This is due to the fact that there is significantly less land in the Southern Hemisphere than in the Northern Hemisphere.
A hemisphere is half of a sphere. If itâs a cold winter in the northern hemisphere, take a winter getaway to sunbathe somewhere in the southern hemisphere. Hemisphere comes from the Greek, and combines the prefix hemi-, for half, with sphere, or perfectly round ball.. We talk about the earth as divided at the equator into the northern and southern hemispheres (or divided at the prime meridian into eastern and western hemispheres).
