When volcanoes erupt, usually land is destroyed AND constructed. These eruptions occur due to the pushing in, pulling apart or sliding of the tectonic plates under the earth's crust. This movement builds up pressure and causes eruptions.
There are smallamount of volcanoes. They emit so2 and co2 gases.
This is where the weaknesses in the earths crust lie and it is the easiest place for lava to spew out of these weaker areas, therefore forming volcanoes

earthquakes and volcanoes change the worl by pollution for example car pollution, Factorys etc...
The land will be flatend and plants such as trees will be crushed.
However, volcanoes are essential to earths survival they act like a safety valve for the planet (it releases pressure)

Volcanoes
Volcanoes are essentially holes in the earths surface through which magma and lava can erupt. when pressure builds up below the earths crust, magma is then forced violently out of the volcanoes.
Volcanoes are caused by the rising of magma in the earths mantle and earthquakes are caused by the colliding of the earths tectonic plates against one another.
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.

Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.
