the internal “magmatic filter” that causes the eruption of oceanic island volcanoes

The volcanoes we see on the Earth’s surface are just the tip of the iceberg. Below the surface, they are fed by a complex network of conduits and reservoirs that bring molten rock, called magma, back to the surface. When the magma erupts, it can generate lava flows that cool down to become volcanic rocks. […]

How are mountains formed? – World Atlas

Mountains are formed by movement within the earth’s crust. The crust itself is made up of several large plates, called tectonic plates, which float freely. These huge pieces of the earth’s crust move through molten rock called magma, allowing them to move and collide over time. Even though humans live on the crust, they don’t […]
