Because the southern states were economies based on slavery and many in the northern states felt that slavery was wrong.
Northern workers opposed slavery; southern planters support it
The Abolitionist Movement!
Before the Civil War, the issue of slavery played the greatest role in increasing tension and conflict between northern and southern states. The North's growing abolitionist movement clashed with the South's economic reliance on slavery for agricultural production. Legislative compromises, such as the Missouri Compromise and the Compromise of 1850, ultimately failed to resolve these deep-seated differences, leading to heightened animosities and the eventual outbreak of war. Additionally, events like the Dred Scott decision and John Brown's raid further inflamed the divide.

No. The big Northern majority in Congress was one of the reasons for North-South tension.

This is due to the significant history of slave ownership in the southern states, that was not part of the culture of the northern states.

The stress in the southern part of the San Andreas fault system is mainly accumulating due to the relative motion between the Pacific Plate and the North American Plate. In contrast, the northern part experiences a more complex system of faults and stress due to the interaction of multiple tectonic plates in the region, including the Pacific, North American, and Gorda Plates.
Tension between the northern and southern states before the Civil War escalated due to several key issues, primarily centered around slavery and states' rights. The North's growing industrial economy and anti-slavery sentiment clashed with the South's agrarian economy that relied heavily on slave labor. Legislative disputes, such as the Missouri Compromise and the Kansas-Nebraska Act, further fueled divisions, as did events like the Dred Scott decision and John Brown's raid. These conflicts culminated in deep-seated animosities, ultimately leading to secession and the outbreak of war.
The major conflict in U.S. history in 1860 was the escalating tension between the Northern and Southern states over issues such as slavery, states' rights, and economic differences. This tension culminated in the secession of several Southern states from the Union following the election of Abraham Lincoln, who was seen as anti-slavery. The conflict ultimately led to the outbreak of the Civil War in 1861, fundamentally altering the nation’s political, social, and economic landscape.
