A volcano is geomorphism caused by the underground magma and its products spurting to the surface. Due to the nature of the magma, the form of the eruption is different, and the form also forms a mountain like it.
Japan has a population of 127 million, and it's the world's tenth largest.
This is Japan! Here!!
Japan has so many volcanoes, but I researched Sakurajima because it is the most active volcano in Japan. I will explain how the volcanoes are created.
Volcanic action involves the release of molten magma from deep below the earth’s surface. When the molten magma is spewed out onto the earth's surface, it's called lava.
Molten Magma (melted rock)
When lava cools off on the earth’s surface, they solidify. This is responsible for the formations of many magnificent landforms. For examples of landforms are created by volcanic action include lava domes, plateaux, and calderas. These landforms are plate tectonics.
