Source sentences:
text: If some mineral crystals start growing while the magma is still underground and cooling slowly, those crystals grow to a large enough size to be easily seen, and the magma then erupts as a lava flow, the resulting texture will consist of coarse-grained crystals embedded in a fine-grained matrix.
text: Similarly, the tops of shield volcanoes collapse when magma erupts as lava flows, emptying the magma chambers.
