When the first people saw lava exploding out of a volcano you can understand why they likened it to fire. Any rock that forms from molten rock is termed igneous.

As a rock melts at great depths under the Earth’s surface, it will

begin to rise (think of a hot air balloon) before eventually cooling down back into a rock. The nearby Mount Piper was formed when lava erupted from the Earth to make a volcano.

On the converse, Mount Disappointment formed in an underground chamber when magma cooled to form granite (as you might see in your kitchen countertop).

Thanks to our Geology team for sharing their rock *star* knowledge
