Volcanic domes commonly are partially destroyed when

When you have seen a land formation which is in the shape of a rough circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano, then most probably what you are seeing is a lava dome or a volcanic dome. Some of these lava domes’ geochemistry vary from basalt to rhyolite. Although the usual content are those mentioned, most of the preserved domes tend to have high silica content. The sleep flanks can partially destroy the domes. These can result to the collapsing and breaking into a jumble of blocks and ash that flow downhill. These domes can also be destroyed due to the explosions inside them. This happens when trapped gas builds up so much inside that it can no longer be held.

condensation. good luck!

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
