The video explains how volcanoes help us understand Earth's interior. It describes the process of rock melting into magma deep inside the Earth, which can push its way to the surface and erupt as lava. This lava flows down the volcano and solidifies into rock. The video emphasizes the significance of volcanoes in revealing the geological processes of our planet.
