An example of igneous rock is basalt. Igneous rocks are formed from the solidification and cooling of magma or lava. Basalt is an extrusive igneous rock, which means it formed from lava that erupted onto the Earth's surface and cooled quickly. Basalt is a dark-colored rock that is typically fine-grained and dense. It is commonly found in areas of volcanic activity, such as mid-ocean ridges and hotspot volcanoes. It is also used as a building material and in road construction due to its durability and strength.
