How Does Volcanoes Change Earths Surface?

Primarily, it is the lava contained within the volcano that alters the surface of the earth. After a volcanic eruption has taken place, the extremely hot lava that has been released will flow to the earth’s surface, changing the configuration of the earth’s surface upon its landing. This change occurs, as when the lava cools, it sets upon the ground, consequently producing solid rock. This can make the Earth’s surface appear rough and uneven, but it also makes the land more fertile. During this eruption, many materials are released, such as cinder, pumice and ash. Cinder is the released dark coloured pieces of ash; pumice is the bubbly, frothy rock that becomes hardened, and ash is the fine-grained particles.

These pieces of rock and particles, in addition to the lava flows, significantly affect the surface of the earth, as it is these materials that build up to create cones of volcanic mountains.

Depending upon the magnitude of an eruption, the gases released from a volcano can impact on global warming. In turn, this will reduce the amount of solar radiation reaching the earth’s surface, therefore altering the said surface as a result. Ash and water vapour are normally greatly distributed after an eruption, changing not only the appearance but the texture of the Earth’s surface; affecting the inhabitants of that area, too. Moreover, the heat of the erupted lava has been known to cause fires, which can have disastrous effects upon the surface of the Earth.

Furthermore, there are other ways in which a volcanic eruption can alter the Earth’s surface. Volcanoes can trigger mudflows, avalanches, tsunamis in addition to cracks and fissures in the Earth’s surface.

Volcanoes push up the earth. They form mountains and plateaus. They also make new ground and provide fertile soil. That is how they change the earth's surface.

A volcano is basically an opening in earth's surface. During a volcanic activity, hot and molten gases, rocks, ash etc comes out from this rupture in the earth's surface. Over a period of time, this volcanic activity tends to form mountain like features on the surface of earth. This activity can be referred to building of land by volcanoes.

The surface of the earth is constantly changing. Forces like wind, glaciers, and water erode its surface. And the forces like volcanoes raise the surface of Earth and form a mountain or new land. For more information see the link below:

Starting below sea level a volcano Is born. Eventually that volcano will erupt and grow bigger and bigger. Depending on how far below sea level and how big the eruptions are the volcano will eventually peak out of the ocean. Continuing to erupt and grow the volcano will create a landmass above the sea level. Some volcanoes have become "inactive" and stop their spontaneous blow-ups. The new "land form" will start supporting life of vegetation, animals and eventually humans.  You now have a land form.

Technically a volcano does not "create" a new land form. Land forms do not only exist above water. The also consist of features bellow water. As a part of terrain the whole surface is a "land form".

After the lava they spew out cools it hardens and forms rocky layers changing the shape of the surface.

Volcanoes change Earth's surface by lava spewing out and cooling and making NEW LAND! (go figure).

After a volcanic eruption there is a uplifting of earth crust occur,lot of minerals as well as rock varieties come to the  earth surface this cause to formation of new rock types on earth surface.after lava flowing the soil get enriched with fertilizers.

By the eruptions in the earth that have the vibration

With nature disasters really anything dealing with nature anything can happen like like plants population increasing whish is getting a bigger percentage than water being on earth.

Rapid or slow process

VOLCANOES themselves are changes in the earths surface

The ash that thee volcano releases will block out the sun, causing problems with plants and every other living organism since all living things need the sun. :)

They  burn all the plants and kill all the animals also they make all the trees fall down.

When a volcano explodes it creates a new island on earth that has water surrounding it it is just adding on to the earths islands created by volcanoes.

After a volcano erupts mountain like structures form.   This is also known as the building of land by volcanoes

Volcanoes change the earth by melting rocks and and making new land.
