Comments (5) on “How did volcanoes change earth in the first two billion years?”
The volcanoes provided, on the surface of the earth, the heat, water and the powerful cocktail of organic compounds (hydrogen sulphide, arsenic) that are at the beginning of life. In fact, the primitive organisms are for 2 billion years, fed by this soup, which makes scientists say that volcanic lakes are one of the possible cradles of life. The volcanoes not only kept life but also protected it in a distant time when the sun warmed our planet much less than today.
The intense performance of CO2 (carbon dioxide) volcanoes allowed the Earth's heat to fix itself permanently in our atmosphere. It is thanks to volcanic cataclysms that our planet was able to leave its frozen sphere state. In fact there are about 600 million years, an intense glacial period fell on the Earth, glaciers were present everywhere, the polar caps descended to the equator that covered the entire surface of the planet.
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.

They outgassed water vapor and carbon dioxide into the atmosphere.
I would say yes because it moves the ground and then it starts to rumble

I hope this helps!
The anwser is A. The atmosphere has nothing to do with Volcanoes chaning the earth landform
