* Crater: This is the most common feature. It's a bowl-shaped depression at the top where the volcano erupts.
* Caldera: A much larger depression, formed when a volcano collapses after a large eruption.
* Lava Dome: A mound of solidified lava that can form within the crater.
* Volcanic Plug: A solidified column of lava that plugs the vent, preventing further eruptions.
* Fumaroles: Vents that release steam and gases.
* Ash Cone: A small, cone-shaped hill formed from volcanic ash.
* Summit Ridge: A sharp, rocky ridge that forms the rim of the crater.
The specific features on a volcanic summit depend on the type of volcano and its history of eruptions.
