how are basalt columns formed? - ask an earth and space

It’s due to a physical process that can happen in melted lava rock as it cools. Imagine a huge flow of hot, liquid magma that is settling. The outer layer is starting to cool and darken in color from orange to black. As it cools, it needs to shrink a bit, as hot materials usually take up more space than cooler ones
