- Lava lake
Lava lakes are large volumes of molten
lava , usuallybasaltic , contained in a vent,volcanic crater , or broad depression. Scientists use the term to describe both lava lakes that are molten and those that are partly or completely solidified. Lava lakes can form in one of three ways:
#From one or more vents in a crater thaterupt s enough lava to partially fill the crater
#When lava pours into a crater or broad depression and partially fills the crater
#Atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater higher and higher above the surrounding ground.ee also
