At 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 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.
Where are melts most likely to be produce by the adiabatic rise of mantle?
Melts are most likely produced by the adiabatic rise of mantle material at divergent plate boundaries, such as mid-ocean ridges. As mantle material rises due to the reduction in pressure, it undergoes decompression melting, leading to the formation of magma.
How is volcano formation at the divergent boundaries?
as the plates separate , hot rock from the upper mantle is drawn upwards and it partially melts
Why is the lava mostly mafic at divergent plate boundaries and intermediate and felsic at convergent plate boundaries?
Mafic magma has extremely high ferromagnesian content, produced by decompression melting. As the plates move apart, mantle rises to fill the void. As it melts, it forms mafic magma. Where plates are meeting, the compression of crust forms magma with higher silica content, thus forming felsic and intermediate magmas.
Can minerals crystallize out of magma when it melts?
Yes, minerals can crystalize when magma melts.
How igneous rock become igneous?
because when it melts it turns in to magma
What plate tectonic settings would you find basalts?
Basalts are primarily found at divergent plate boundaries, such as mid-ocean ridges, where tectonic plates are pulling apart and magma rises to fill the gap. They are also common at hotspots, where mantle plumes generate volcanic activity, and at convergent boundaries, particularly in subduction zones, where oceanic crust melts and produces basaltic magma. Additionally, basalts can form in rift zones, where continental plates are splitting apart.
Which type of landform develops at plate boundaries in the ocean magma rises and melts?
At plate boundaries in the ocean where magma rises and melts, mid-ocean ridges develop. These underwater mountain ranges form as tectonic plates pull apart, allowing magma from the mantle to ascend and solidify. This process creates new oceanic crust and can lead to volcanic activity along the ridge. Additionally, this setting can result in the formation of hydrothermal vents, which are unique ecosystems dependent on the heat from the magma.
When a rock melts it turns into what?
When a rock melts, it turns into magma, so when the magma cools, it can make a new igneous rock.
Can cars survive in lava?
no because the hott high temperature melts what touches it just like rocks you put arock in it it melts and turns to magma
What are all the plate boundaries?
There are three main types of plate boundaries: divergent boundaries (plates move apart), convergent boundaries (plates move towards each other), and transform boundaries (plates slide past each other). Each boundary type can result in different geologic features and events such as earthquakes, volcanic eruptions, and mountain building.
