VOLCANIC ERUPTIONS

                                      VOLCANIC ERUPTIONS

A volcano is a rupture on the crust of a planetary mass object, such as the Earth, which allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

My opinion of the volcanic eruptions is that are very dangerous because the volcanic eruptions can disappear one town and cover it with ashes. 

Volcanos produce a number of hazards depending on the type of volcano. Even a volcano that is not erupting can release toxic gasses and cause earthquakes, though major earthquakes are rare.

Volcanos are dangerous to people because: 

1. Depending on how explosive the eruption is (which depends on the magma type), and depending on how close a city is to a volcano, the lava (which flows slowly) could burn and set things on fire.

2. The ash could block off the sun, destroying crops and food. 

3. If the ash and gases released were breathed in, it could cause lung cancer. 

4. Homes can be destroyed. Transportation like airplanes or cars can't be used because the ash would clog the engine and it would stop working. 

5. The pyroclastic flow would kill people instantly (inside the flow is intense heat that would burn things alive)

volcanoes appear when two plate boundaries either move away from each other or move closer to each other. New land is made by lava solidifing in gaps in the earth.

But the volcanoes can't appaer just anywhere they can only appear in hot spots,divergent plates and convergent plates

Volcanic eruptions

The volcanic eruptions are very dangerous because it can bury a city like Vesuvius do it with Pompeii.

The scientists says that this kind of eruptions occur every 20,000 years. There have been more than 50,000 eruptions in Earth's story. Some of the most important eruptions in Mexico are: paricutin, popocatepetl, and so many more. And there are even volcanoes in other planets, for example, in Mars there is the Olympus mount, the biggest volcano that the human has discovered. Eduardo Hdz and Diego T Lopez

  

VOLCANIC ERUPTIONS

                                   "Volcanic eruptions"

There are a lot of hot substances inside the earth. Sometimes these substances go up to the surface and they come out trough volcanos. 

The substances that the volcano expells can be solid, like ash. They can also be liquid like lava. Volcanos expel gases that can cause explosion inside the volcano.

Also sometimes volcanic eruptions can create islands such as Hawaii.

Sometimes their eruption can be very strong that can disappears city such as Pompeii.

 

We think volcanic eruptions are natural disasters that we can't control, but we know what to do in case of a volcanic eruption.

VOLCANIC ERUPTIONS

                                        Volcanos

The volcanoes grows like a big mountain with a big hole at the top with with burning lava. 

The lava is hot because the center of the planet (the nucleum) The nucleus of the Earth is a natural electromagnet which takes electricity from the universal field to produce a magnetic field. The nucleum keeps warm the magma.A volcano is a rupture on the crust of a planetary mass object, such as the Earth, which allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

In my opinion my volcanos are to impressive . Volcanos grow because  deep inside Earth, between the molten iron core and the thin crust at the surface, there is a solid body of rock called the mantle. When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt.
