Igneous rocks form when a volcano erupts and the hot lava cools. Igneous rocks have many different textures. The texture is determined by how quickly the rocks cool. Those that form on or near the surface tend to cool rapidly, giving the rock a fine grain, such as basalt, the most common rock on the ocean floor. Those igneous rocks that form deep below the surface tend to cool more slowly and, as a result, tend to be tough with a coarse grain, such as granite.

European traders captured some Africans in raids along the coast, but bought most of them from local African or African-European dealers. These dealers had a sophisticated network of trading alliances collecting groups of people together for sale.

Most of the Africans who were enslaved were captured in battles or were kidnapped, though some were sold into slavery for debt or as punishment. The captives were marched to the coast, often enduring long journeys of weeks or even months, shackled to one another. At the coast they were imprisoned in large stone forts, built by European trading companies, or in smaller wooden compounds.

When the slave ships arrived from Europe they were laden with trade goods. Captains offered gifts to local African leaders and paid taxes for the right to trade. They then began the serious business of barter and exchange, offering a wide variety of trade goods such as textiles, firearms, alcohol, beads, manillas and cowries.
