What are the causes of the civil war and how was it connected to slavery

the civil war happened between Northern states and southern states because the northern states wanted abolish slavery and the southern states didn't want to.

Explanation:

*the northern states were called the "union states".

*the southern states were called the "confederates"

Now the reason why the southern states didn't like the idea of abolishing slavery was because the confederates were farmers and the state was in an agricultural type of time and they wanted the slaves to do their job in farming and abolishing these slaves, for them it meant that they were the ones who needed to work.  

the civil war ended with the union states winning and abolishing of slavery started.  

the captain of a steam ship naturally chooses the shortest route to his destination. since a sailing ship is usually pushed by winds and currents, its captain must find a route where the wind will probably blow in the right direction. tacking, i.e. using contrary wind to pull (sic) the sails, was always possible but wasted time because of the zigzagging required, and this would significantly delay long voyages. the early european explorers were not only looking for new lands. they also had to discover the pattern of winds and currents that would carry them where they wanted to go. during the age of sail winds and currents determined trade routes and therefore influenced european imperialism and modern political geography. for an outline to the main wind systems see global wind patterns.

pilotage or cabotage, in one sense, is the art of sailing along the coast using known landmarks. navigation, in one sense, is the art of sailing long distances out of sight of land.[1] although the polynesians were able to sail the pacific (with great difficulty) and people regularly sailed north and south across the mediterranean, before the time of columbus nearly all sailing was coastal pilotage
