Brrrr! if i were them i would worry about toxic gasses. its pretty much a giant well, isn't it? i wonder what they would do if magma started leaking into the chamber. well, except the magma wouldn't be magma anymore because it would have touched air become lava. i wonder where the lava (magma) went?
I think it would be cool to vist the inside of a volcano for these two reasons.
First I think it would be cool to feel th tempiture. I wounder if it would be warm because it is so clouse to the center of the earth. If so, how warm?
I also wonder what it would feel like atitude wise. I think it would be hard to breath. But I might be wrong.
In concluliosn, I think it would be preaty cool!
