What type of magma forms at mid-ocean ridges? What happens after magma is formed? Which igneous rock forms when basaltic lava hardens? What forms when a large volcano collapses in on itself? What are the two types of magma? In what ways can magma be generated from solid rock?
When two tectonic plates slowly move away from each other it creates a divergent boundary. As this happens, magma rises from the Earth’s mantle into the widening gap between the plates. When it reaches the surface it forms solid rock, creating new crust material. Divergent plate boundaries of...
hugetectonic platesare slowly moving and jostling against each other. At the boundaries between plates, where two or more come together, magma creeps up to the surface. The volcanoes of the Pacific Rim have been built up this way, where plates slide together...
What happens to a substance when it melts? When a substance melts, it transitions from a solid state to a liquid state. 2 Is "molten" a permanent state? No, "molten" is a temporary state; the substance solidifies again as it cools. 2 Share Your Discovery Share via Social Media Embed...
What happens at a subduction zone? Tectonic plates are pieces of the Earth’s rigid outer layer that slowly move across the planet's surface over millions of years, according toNOAA. (This is the main tenet ofplate tectonics, the theory that portions of Earth's shell glide over the lower...
