11SCI Volcano Internal

Name and describe specific features of the Onepoto volcano.

Onepoto is a ❌ volcano ❌ meters deep and ❌ meters wide. ❌ from a hot spot 100 km down formed Onepoto’s ❌. Onepoto used to be a crater that is now ❌ due to sediment buildup. The sides of the tuff ring is relatively steep, with a ❌ on the ❌ side due to ❌ and erosion to use for manmade purposes such as the construction of the harbor bridge and the roads leading up to the volcano. The tuff ring has plenty of ❌ on top of it.

Discuss, in detail, how internal processes have contributed to the formation of the features you described in your chosen volcanoes.

❌ from a ❌ 100 kilometres down makes its way up, surfacing from a crack or a ❌ in the Earth’s crust.

As ❌ encounters ❌, steam is generated and pressure builds up, leading to a ❌ explosion. In a phreatomagmatic explosion, ❌ is thrown up into the air while heavier ❌ is pushed ❌. This creates a ring of ❌ and sediment that gradually hardens into a ❌.

Time passes, and the volcano may stop erupting. Water would collect in the crater hole. At this point, tuff ring volcanoes like O❌ and T❌ becomes extinct.

However, some volcanoes like M❌ and N❌ continue to erupt. Additional lava rises in the vent and a ❌ is formed.

If there is plenty of lava, fire / ❌ begins. ❌ start to build up around the vent.

Lava / fire fountain continues, and scoria cones also continue to ❌. Lava may burst out at a low level, like ❌, flowing to fill the surrounding valleys and areas.

The lava flow, like Mount Victoria, may have been so significant that it ❌ of the scoria cone. The cone ❌ into the lava flow and is carried away. This leaves a ❌ in the crater.
