The igneous rock that forms outside on the Earth's surface is called extrusive igneous rock, commonly exemplified by basalt and pumice. These rocks are formed from the rapid cooling and solidification of lava that erupts onto the surface during volcanic activity. Due to the quick cooling process, extrusive igneous rocks typically have fine-grained textures, with small or no visible crystals.
