Final answer:
The correct chronological order is: Missouri Compromise, Compromise of 1850, Kansas-Nebraska Act, Dred Scott Decision.
Step-by-step explanation:
The correct chronological order to illustrate a cause-and-effect relationship among the events leading to the Civil War is:
The Missouri Compromise
The Compromise of 1850
The Kansas-Nebraska Act
The Dred Scott Decision
The Missouri Compromise of 1820 allowed Maine to enter the Union as a free state and Missouri as a slave state, maintaining the balance between free and slave states. The Compromise of 1850 dealt with the admission of California as a free state and the strengthening of the Fugitive Slave Act.
The Kansas-Nebraska Act of 1854 permitted popular sovereignty in Kansas and Nebraska, leading to conflict over the expansion of slavery. The Dred Scott Decision of 1857 stated that slaves were not citizens and Congress could not outlaw slavery in the territories.
