If you see a dark mass similar to a blown-up balloon at the top of a volcano, what type of feature are you most likely viewing? a lava dome

a flood basalt plateau

a geyser

a newly formed island

Sorry I marked it as physics, because it should be science but there isn't a subject for that :(

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
