Igneous is a word that describes a certain type of rock, specifically rocks that are formed from magma or lava that has cooled and solidified. This can happen either above or below the Earth's surface, and the resulting rocks can look very different depending on how they formed. Some common examples of igneous rocks include basalt, granite, and pumice. If you are studying geology or other earth sciences, you may encounter the word igneous frequently as a way to describe different types of rocks and their properties.
