Which force changes the lithosphere by building up the surface?
Sunny_sXe [5.5K]

Answer:

volcanic eruptions

Explanation:

The volcanic eruptions are the ones that manage to cause changes to the lithosphere by building up new material on the surface. Through the volcanic eruptions we have release of pyroclastic material on the surface, and more importantly and in much higher amount lava flows. The lava flows quickly cool off on the surface on the Earth, and as they do they pile up new layers of igneous rocks, thus new crust on the surface of the Earth, causing changes on the lithosphere and shaping it for the foreseeable future.
