How do rocks get stripes?

Striped patterns in stones are usually caused by layers of sediment that have accumulated over time. … Much of Earth’s history is recorded in layer upon layer of sediment. This is one of the fundamental concepts of geology. When a layered rock is quarried and sawn into blocks, its layers look like stripes.

What do igneous rocks look like?

Igneous rocks can have many different compositions, depending on the magma they cool from. They can also look different based on their cooling conditions. … If lava cools almost instantly, the rocks that form are glassy with no individual crystals, like obsidian.
