What type of rock is formed by quickly cooling lava?
extrusive igneous rock
When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.
What type of crystal grain forms when molten rock cools slowly?
igneous rock
magma that cools slowly will form an igneous rock with large crystals. lava that cools quickly will form an igneous rock with small crystals….What are igneous rocks like?
| Extrusive | Intrusive | |
|---|---|---|
| Examples | Obsidian and basalt | Granite and gabbro |
