lava dome
A lava dome is a steep-sided, mound-shaped volcanic feature formed by the slow extrusion of highly viscous lava that piles up near a volcanic vent.
-
D.
alkaline lake
An alkaline lake is a body of water with high concentrations of dissolved carbonates and bicarbonates, resulting in a high pH and often unique, highly specialized ecosystems.
-
E.
crater lake group
A crater lake group is a collection of lakes that occupy volcanic craters or calderas formed by past eruptions, often studied together for their shared geological origin and hydrological characteristics.
- F. None of above. chosen
