How does a volcano change the earth's surface?

Answer 1

Volcanoes can change the surface of the earth in several ways. The lava that is ejected for the volcano may dry and form a new layer of sediment on the ground. The chambers of magma underground can become too pressurized and make a whole new volcanic mountain. Hope that answers your question! :D

Answer 2

Due to the fact that when the lava cools, turns into rock. This is why the surface of the Earth changes because of the formation that the lava is going to make. For example, if you go to the beach and you see a hole in the sand, then if you want to get rid of that hole you will have to put some sand in there.
That's what the lava does, once it flows in the surface of something, it will stuff in there when it gets cold (Earth surface)

Hope this helped

Answer 3

when volcanoes erupt the lava dries and then forms new layers of sediment on the ground then it may become too pressurized and create a new volcanic mountain. :) hope i helped toodles - panda malik <3

Answer 4

They bring magma up to the Earth's surface, and depending on type, can form both the volcanoes themselves as peaks, and large-scale "flood basalt" plateaux such as the Deccan Trappes (in India), their Siberian equivalents and what we see now as the Giant's Causeway and the Isle of Staffa (which holds the sea-cut Fingal's Cave)

Answer 5

volcanoes change the earths surface due to the lava set hard and drys which can make the surface bobbly and ruff also it makes the land more fertile

Answer 6

The lava is so hot, that's why it melted the surface of the earth.

Answer 7

Because a volcano's surface like goes up a lot with a hole at the top the Earth's surface will not be flat
