What type of solid rock forms on a volcano from the lava during an eruption?

Igneous rocks are formed after solidification of lava (Magma inside earth). They are rich in metals as metals are found deep in earth and hence they come out in molten state with the lava.

What is a event when a volcano enjects gas liquid and solid materials into the atmosphere and surrounding area?
This is the description of a volcanic eruption.A eruption.
What is ejected debris?
"Ejected debris" the the solid material shot into the air by an erupting volcano (as opposed to the gasses ejected by the same eruption).
What are tha things you do after and before during the volcanic eruption?
you are asking a seemingly simple question but it has a complex answer. Prior to an eruption you have the forming of the caldera. Then you have the eruption: here are some effusive eruption, central vent eruption,fissure eruption, subaqueous eruption, sub glacial eruption, pyroclastic eruption, ash-flow eruption. The most spectacular of all of them is the pyroclastic eruption. It throws off viscous gas-rich magmas and producesw a great deal of solid volcanic fragments. A volcanic eruption after is called clean up. The included link about Mt St Helens eruption will give you an idea on the potentially explosive power of a volcano.
Why do some volcanoes erupt and some dormant?
Whether a volcano should erupt or not depends on the pressure building up in the mantle underneath. In some areas, the solid cap formed over a dormant volcano is sufficient to prevent a new eruption. In this case, the pressure could move away to find a weaker area and a new eruption and the birth of a new volcano could appear.
