Final answer:
The Compromise of 1850 included popular sovereignty in new territories, and the enforcement of the Fugitive Slave Act, along with other measures to balance northern and southern interests around the issue of slavery.
Step-by-step explanation:
The Compromise of 1850 proposed several solutions to the issue of territorial expansion and slavery. It did not call for the immediate abolition or the expansion of slavery to all territories. Instead, it included the enforcement of the Fugitive Slave Act, admitted California as a free state to balance the South's interests, established the boundary between New Mexico and Texas with concessions to the North and the payment of Texas's debts, and banned the slave trade in Washington, D.C. Most importantly, it introduced the tactic of popular sovereignty in the New Mexico and Utah territories, allowing residents to decide the legality of slavery.
