Extrusive rocks are formed from lava that cools quickly on the Earth's surface, resulting in fine-grained textures such as basalt or rhyolite. They often contain vesicles or cavities formed by gas bubbles trapped in the lava. Extrusive rocks tend to be dark in color and have a lower silica content compared to intrusive rocks.
