Explain 2 causes for the Civil War and 2 effects the war had on this country. Be sure to clearly list and explain the causes and effects. Thanks.

A key issue was states' rights and  territorial expansion.

Explanation:

states rights:

The Southern states wanted to assert their authority over the federal government so they could abolish federal laws they didn't support, especially laws interfering with the South's right to keep slaves and take them wherever they wished.

territorial expansion:

The South wished to take slavery into the western territories, while the North was committed to keeping them open to white labor alone.

mass production/ assembly line production
