How hard is cooled lava? Flowing basaltic lava has a temperature of about 1200°C, but it cools quickly when it’s exposed to ambient air. So quickly, in fact, that instead of forming a hard rock that you would normally imagine, the lava you scoop up with a rock hammer cools to a fragile (but pretty incredible) piece of volcanic glass.
What will molten lava cool to form? Lava cools to form volcanic rock as well as volcanic glass. Magma can also extrude into Earth’s atmosphere as part of a violent volcanic explosion.

Those shapes are forming because of how the lava cools. It starts at different spots called “centers.” If those centers are evenly spaced, the forces that pull inward toward the centers end up creating different chunks of cooling lava that are hexagonal (6-sided), or close to it.
