How do volcanoes change earth's surface?

Volcanoes czn change the earths surface, because over time, the lava from the volcanoes builds up, and creates and destroys land over time. We can look a for example Hawii, USA. This state is made up of small islands that were created by volcanoes, that are constantly changing the land.

I hope this helps!
