What else can I help you with?
At divergent plate boundaries in the ocean magma rises and melts because of?
Because of a decrease in pressure.
What causes the rocks in the mantle at divergent boundaries to melt?
Rocks in the mantle at divergent boundaries melt due to the decrease in pressure as tectonic plates move apart. This reduction in pressure lowers the melting point of the rocks, causing them to melt and form magma.
Volcanism is common at convergent and divergent boundaries of?
tectonic plates, where magma from the mantle rises to the surface. At convergent boundaries, one plate sinks beneath the other, creating intense heat and pressure that can lead to volcanic activity. At divergent boundaries, plates move apart, allowing magma to well up and form new crust.
What types of boundaries are associated with volcanoes?
plates moving together
Can rocks melt at plate boundaries?
Yes, rocks can melt at plate boundaries, particularly at divergent and convergent boundaries. At divergent boundaries, tectonic plates pull apart, allowing magma from the mantle to rise and create new crust. At convergent boundaries, one plate may be forced beneath another in a process called subduction, where increased pressure and temperature can cause rocks to melt, forming magma. This melting can lead to volcanic activity and the formation of igneous rocks.
What divergent plate boundaries in the ocean magma rises and melts because of?
Because of a decrease in pressure.
At divergent plate boundaries in the ocean magma rises and melts because of?
Because of a decrease in pressure.
Why do you find volcanoes at convergent and divergent boundaries but not at transform boundaries?
Convergent and divergent boundaries melt rock in the upper mantle while transform boundaries do not. Convergent boundaries that involve at least one oceanic plate form subduction zones, where an oceanic plate plunges into the mantle. Volatiles carried into the mantle lower the melting point of the rock there, allowing magma to form.At divergent boundaries the crust becomes thinner. This reduces pressure on the upper mantle, thus lowering melting points and generating magma.Transform boundaries have no such means of producing magma.

At divergent plate boundaries in the ocean magma rises and melts because of what?
Magma rises and melts at divergent plate boundaries in the ocean due to the decompression melting that occurs as tectonic plates move apart. As the plates separate, pressure on the mantle decreases, causing the mantle to melt and create magma that rises to the surface, forming new oceanic crust.
Can rocks melt at plate boundaries?
Yes, rocks can melt at plate boundaries, particularly at divergent and convergent boundaries. At divergent boundaries, tectonic plates pull apart, allowing magma from the mantle to rise and create new crust. At convergent boundaries, one plate may be forced beneath another in a process called subduction, where increased pressure and temperature can cause rocks to melt, forming magma. This melting can lead to volcanic activity and the formation of igneous rocks.
What causes the rock in the mantle at divergent boundaries to melt?
The crust stretches and gets thinner so the pressure decreases on the mantle rocks below this causes part of the mantle to melt
How does magma form at convergent and divergent boundaries?
At divergent boundaries, two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below.
Mafic magma is generated at divergent boundaries because of?
Mafic magma is generated at divergent boundaries because of decompression melting caused by the upwelling of hot mantle material due to the pulling apart of tectonic plates. As the plates move away from each other, the decrease in pressure enables the mantle material to melt and form mafic magma.
Why are most volcanoes located near a fault?
Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
