volcanic formation
Magma-carved terrain feature
A volcanic formation is a geological structure created by volcanic activity, including features like craters, calderas, lava domes, cinder cones, and volcanic islands.
These formations result from the eruption of molten rock, ash, and gases from beneath the Earth's surface, often producing distinctive landforms that persist long after volcanic activity has ceased.
The Hawaiian Islands are volcanic formations rising from the ocean floor.
