A. Both mountains and volcanoes have the same outward appearance. However, mountains are formed by movements of tectonic plates, whereas volcanoes are formed from pockets of magma that rise up during eruptions.
B. Both mountains and volcanoes are formed by the same process of movement by tectonic plates. However, volcanoes can grow to be much higher than mountains because they also grow from pockets of magma that rise up during eruptions.
C. Both mountains and volcanoes are formed from pockets of magma that rise up during eruptions. However, mountains can grow to be much higher than volcanoes because they also grow from movement by tectonic plates.
D. Both mountains and volcanoes have the same outward appearance. However, volcanoes are formed by movements of tectonic plates, whereas mountains are formed from pockets of magma that rise up during eruptions.
Tectonic plates move around and when they collide upward, they create mountains and volcanoes, mountains become much taller because there is an absence of magma pockets. Volcanoes usually form when pockets of magma rise to the surface with activity below the earth's crust.
