Picture of Volcano Explotion
You'll probably ask what did we create for our science fair.
We made a volcano... but, why did we do a simple volcano? It's easy, well... volcanos are not a simple thing, I mean, they are not just a rupture in the surface which allows hot lava and volcanic ashes.
Generally, they're formed at the boundaries of the tecntonic plates, inside has open fires where the lava rises from the magma chamber, a reservoir where lava accumulates.
So, what we did for our science fair was a little volcano which would represent a real volcano eruption so people could understand better the process it requires.

Step 1: Volcanoes!

Picture of Volcanoes!
First we have to know what is a volcano.
A volcano is an opening, or rupture, in a planet's surface which allows hot, molten rock, ash, and gases to escape from below the surface. Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a period of time.
Volcanoes are generally found where tectonic plates are diverging. Volcanoes can also form where there is stretching and thinning of the Earth's crust.

Step 2: How volcanoes work?

Volcanic activity ranges from emission of gases, lava emissions to extremely violent explosive bursts that may last many hours. The types of eruptions determine the relative volumes and types of volcaniclastic material and lava flows, consequently the shapes and sizes of volcanoes.

A volcanic event occurs when there is a sudden or continuing release of energy caused by near-surface or surface magma movement. The energy can be in the form of earthquakes, gas-emission at the surface, release of heat, which is geothermal activity, explosive release of gases (including steam with the interaction of magma and surface of ground water), and the non-explosive extrusion or intrusion of magma.
An event could be non-destructive without release of solids or magmatic liquid, or if there is anything to destroy, could be destructive with voluminous lava flows or explosive activity. Destruction usually refers to the works of mankind (buildings, roads, agricultural land, etc.).

Nice work!
