What is the approximate proportion of southern population to northern population

3:7

Explanation:

The American civil war was a war between the Southern part of the United States of America and the Northern part of the United States of America. The civil war started on the 12th of April, 1861 and ended on the 9th of April, 1865. The cause of the war was the issue of slavery over black people, rights and crisis of territory.

Other cause for the war was because Abraham Lincoln won the election. The southern leaders though the President, Abraham Lincoln would stop slavery.

During the American Civil war, about 70 percent of the United States of America resided in the Northern part of the country while 30 percent resided in the Southern part of the country.

Therefore, the approximate proportion of southern population to northern population is 30/70= 3:7.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
