By the 1820s, the controversy surrounding the Missouri Compromise had quieted down considerably, but was revived by a series of events near the end of the decade. Serious debates over abolition took place in the Virginia legislature in 1829 and 1831. In the North discussion began about the possibility of freeing the slaves and then resettling them back in Africa (a proposal that led to the founding of Liberia).

Explanation:
Precambrian time, period of time extending from about 4.6 billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, 541 million years ago. Precambrian time encompasses the Archean and Proterozoic eons, which are formal geologic intervals that lasted from 4 billion to about 541 million years ago, and the Hadean Eon, which is an informal interval spanning from 4.6 billion to 4 billion years ago. The Precambrian represents more than 80 percent of the total geologic record.
