उत्तर
Extrusive landforms are formed when the lava cools down after coming out on the surface of the earth. Lava is made up basalt.
Explanation:
Lava is molten rock that cools quickly on the earth’s surface forming extrusive igneous rocks. Basalt is the most common rock formed from cooled lava, characterized by fine-grained crystals due to rapid solidification. Marble, limestone, and sandstone are sedimentary or metamorphic rocks, not lava-derived.
