This fills in the gap created by the plates diverging. This sort of magma production is called spreading center volcanism. At the point where two plates collide, one plate may be pushed under the other plate, so
The water in geysers is heated by magma that lies around 3 miles (4.8 kilometers) beneath the surface of the Earth. While that might seem like a long way down, magma underneath a geyser field is actually relatively close to the Earth's surface. There are different reasons why the magma ...
Log In Sign Up Subjects Science Plate tectonics How does subduction produce magma?Question:How does subduction produce magma?Subduction:Subduction is the process of one tectonic plate being forced down toward the mantle at a convergent plate boundary. This usually happens when a continental plate...
Lamproite Magma:Less common than kimberlite but similar in composition, it can also carry diamonds to the surface through explosive eruptions. Eruption Process The speed of these eruptions is essential to preserve diamonds. Rapid ascent allows the diamonds to avoid exposure to lower pressures that co...
How is the oceanic crust destroyed?Magma:Magma is a mixture of exceedingly hot liquid and a semi-molten rock found at the surface of our planet, formed by the melting of rocks in the mantle. Magma causes volcanoes whereby it pushes through a hole in the crust, and like a solid rock, ...
In these eruptions, magma travels rapidly from deep within the mantle, often passing through a diamond stability zone on its route to the surface. Pieces of rock from the diamond stability zone may be torn free and carried rapidly upwards to the surface. These pieces of rock are known as "...
This fills in the gap created by the plates diverging. This sort of magma production is called spreading center volcanism. At the point where two plates collide, one plate may be pushed under the other plate, so that it sinks into the mantle. This process, called subduction, typically forms...
During magnetic surveys of the sea floor, the researchers located a giant volcanic region where, for “at least 40 million years, molten magma flooded out of cracks and fissures as the continent stretched and thinned like pizza dough,” Mortimer wrote. While the scientist is nearing retirement...
goes into theEarth. As this plate gets lower it slowly starts to melt and becomesmagma. Scientists know that the plate is destroyed because of the Law of Conservation of Matter, which states that matter cannot be created or destroyed, only recycled. As the new plate material is created, ...
