A. Plate movement causes sedimentary basins to form at divergent boundaries, which are rich in iron ore. B. Convergent plate movement squeezes and metamorphoses rocks, often creating iron ore deposits. C. Transform plate movement stirs up underground magma, leading to the formation of iron ore....
How does magma form over an active subduction zone? How are igneous rocks formed from a subduction zone? How is basaltic magma transformed into felsic magma? How are volcanoes formed by plate tectonics? How does water create magma during subduction at a divergent boundary? In other words, how...
Where does basaltic magma form? How do minerals form around chimneys on the ocean floor? How is magma classified? How can magma be called a solid under the surface if it is made of molten rock? How does water create magma during subduction at a divergent boundary? In other words, how do...
Divergent boundaries are also known as spreading plates. Here magma rising through the Earth's mantle generates pressure through heat and motion to push plates apart. When these boundaries spread on the sea floor, they're characterized by volcanic activity and the rise of mid-oceanic mountain ridg...
shifting them upwards to create mountains and sometimes volcanoes – or it can bend one of the plates to create a deep marine trench on the seabed. In divergent boundaries, the plates move away from each other on the ocean's floor, often forming deep trenches that allow magma fissures to ...
Question: How many tectonic plates are there? Tectonic Plates: Tectonic plates are the independently moving pieces of the Earth's crust. When they collide, they can form mountains or push one of them down to form a subduction zone. When they spread apart, they create a rift for magma to ...
At the boundaries between these huge plates of rock and soil, the plates sometimes move apart, and magma, or molten rock, comes to the surface, where it's called lava. It cools and forms new parts of the crust. The line where this happens is called a divergent plate boundary. The ...
Magma | Definition & Formation from Chapter 7 / Lesson 1 216K In this lesson, learn the magma definition, where magma comes from, how magma is formed, the mineral composition of magma, and whether magma is a liquid. Related to this QuestionWhat...
When this magma crystallizes, minerals rich in Fe, Mg and Ca form first. These minerals may separate from the magma through gravity settling or other processes, and in turn make the magma depleted in Fe, Mg, and Ca. As these elements continue to become depleted in the magma, it the ...
