a volcano is made of many layers: {| ! colspan="2" | | 1. Large magma chamber
2. Bedrock
3. Conduit (pipe)
4. Base
5. Sill
6. Branch pipe
7. Layers of ash emitted by the volcano
8. Flank 9. Layers of lava emitted by the volcano
10. Throat
11. Parasitic cone
12. Lava flow
13. Vent
14. Crater
15. Ash cloud |}
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
rock. same as a mountain. magma makes up the lava.
It will plug up the volcano, which will usually keep the volcano from erupting for about 100 years. However, after that, the entire volcano itself will explode.
Shield cones
The underground pressure inside of the volcano built up and finally exploded. It was looking for a pathway with the least resistance and the volcano's central lava tube was it.
A volcano can explode when pressure builds up inside it due to trapped gases and magma. This pressure can be released explosively when the volcano erupts, causing an explosion.
magma flows up to form the eruption
A caldera may form inside the crater of a large volcano. A caldera is a large depression caused by the collapse of the summit of the volcano following a massive eruption. It can be several kilometers in diameter.
The stuff inside the volcano was building up,and it broke through the volcano. Then it turned into ash and that's how Pompeii happened.
First, the magma breaks open rocks underneath the volcano. Then, it flows up through cracks of the volcano. After it is all the way to the top, the volcano erupts. Then the magma and lava flows outside the volcano.
Magma is inside the volcano, and it becomes lava when it comes out. :)
You go inside the volcano and light it up and see if it really explodes.
