How dId yhe bands in the rock in the figure form?

It seems there might be a misunderstanding, as I cannot see any figure or image you're referring to. However, bands in rock formations typically form through geological processes such as sedimentation, metamorphism, and volcanic activity. Layers of sediment accumulate over time, and pressure and heat can cause these sediments to compact and crystallize, leading to the banded appearance. Variations in mineral content, grain size, and color can also contribute to the distinct bands observed in rock formations.
