Cambios en la Tierra: montañas en construcción

The video explains the formation of scoria cones through volcanic eruptions, where small rocks and particles are ejected from a volcano. It contrasts this with the formation of the Rocky Mountains, which were created by large forces pushing sections of the Earth's crust upward, resulting in rugged mountain ranges. Not all mountains are formed by volcanic activity; some are shaped by tectonic forces.

Are all mountains formed by volcanic activity? Explain.

What forces contribute to the formation of rugged mountains?
