In the first place they can create mountains and islands in the ocean. they also spew out massive amounts of gas and dust. under most circumstances the effect on the overall environment is not huge, however if one of these eruptions happens in the wrong place they can disrupt air travel, cause massive waves on the ocean or under extreme circumstances put so much dust and gas into the air as to cause changes in the temperature of the whole word it is theorised that a big enough volcanic explosion can make conditions on earth such that very little of life as we now know it would survive.

Which changes on the earth surface are connected to changes below the earth surface?

Changes on the Earth's surface, such as earthquakes, volcanic eruptions, and mountain formations, are usually connected to processes happening below the Earth's surface. These changes are often driven by tectonic plate movements, magma movements in the Earth's mantle, and crustal deformation. Volcanoes, for example, are connected to the movement of magma from deeper within the Earth to the surface.


What are the forces that shapes the earth?

The two internal forces that shape the earth are volcanoes forcing magma through the crust and changes in the crust through forces like collisions.
