HOW VOLCANOES ERUPT
General Statement
What is volcano erupts ?
Volcano eruption is an event that occurs due to deposition of magma in the bowels of the earth is pushed out by high pressure gas.

- Volcanic
Gases
Gases emitted by volcanoes erupting at the time. Gases include carbon monoxide (CO), Carbon dioxide (CO2), Hydrogen Sulfide (H2S), sulfur dioxide (S02), and Nitrogen (NO2) which can harm humans. - Lava
Magma with a high temperature
fluid flowing from the Earth to the surface through the crater. Liquid lava
will flow following the river would freeze while the viscous lava is close to
its source. Lava that solidifies to form a variety of rocks and has been mixed with rocks, water, and other
materials. Lava is very dangerous for people on the slopes of the volcano.
- Dust
Rain
That is a very fine material ejected into the air during the eruption. Since it is very smooth, ash eruption and the wind can be felt hundreds of miles away. Ash eruptions can disrupt breathing. - Hot Cloud
Namely the eruption of the flow swirl like a cloud. In the rolls have a hot incandescent rocks and dense volcanic material with a temperature greater than 600 ° C.
Explanation
- First a volcano makes something called magma from melted rock.
- The magma goes through a circulation.
- The magma goes up the main vent slowly while it is still getting hotter. When the magma is about half way up the main vent it turns into lava.
- While going up the lava continues to get hotter and hotter. Ash and rocks are collected and the lava is getting hotter and hotter while the lava is continuing its way up the main vent.
- When the lava is at the top of the main vent the volcano erupts. The lava blasts out of the volcano along with ash, rocks, and a cloud of dust that is very thick.
- The ash and rock crumble to the ground, but the lava is either moving down the volcano side very slowly or at a high speed. The lava burns down almost everything in its way, and it sometimes leaves bits of things burning.
- The lava from the volcano can cool fast, or sometimes the lava will slowly cool down from its intense heat. Lava that cools slowly forms igneous rocks.
Volcano’s
erupts will happen if the lava from active volcano become hotter and hotter, so
it push out and rising to start it way up to the main vent. When the volcano is
ready to erupt, lava at the top of main vent burst out. So, a volcano said
erupt if there were bursts of lava from the top of main vent.
