What rock that melts underneath earth?
The rock that melts underneath the Earth is called magma. Magma is formed from the melting of the Earth's mantle and can rise to the surface to form igneous rocks when it solidifies.
A majority of the melts in the Earth form through the partial melting of ultramafic mantle rock These newly-formed magmas are?
Rich in magnesium and iron due to their origin from ultramafic mantle rock. They are usually less viscous compared to melts formed from other types of rock. The composition of these magmas can vary depending on the degree of partial melting and the specific mantle source.
Why is the mantle not solid?
Think about the asthenosphere. The molten rocks in this area are so hot, they flow like a fluid. Heat moves from warm areas to cooler areas. As the cool areas heat up, they become less dense and rise. Then they cool and sink. This circular pattern is called a convection current. The convection currents just beneath the earth's crust flow very slowly, causing movement in the earth's plates above them.
Oceanic lithosphere is destroyed at-?
Oceanic lithosphere is destroyed when it is subducted at a convergent plate boundary and forced into the mantle where it melts. You shouldn't use the internet to look up answers on a test. You should use your notes and textbook! DW Thanks for the answer but um, What about people in online school, where the only "textbook" you get is an agenda? yeah the awnser for Gradpoint is Convergent Boundary
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 does felsic?
Heat from the mantle melts part of the lower crust.
Where does felsic form?
Heat from the mantle melts part of the lower crust.
What happens when th ocean crust melts in the mantle?
it makes more magma.
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.
What is an area where magma from deep within the mantle melts through the crust above?
Hot spot.
When solid rock in the earths mantle melts it forms a liquid rock known as?
Magma
Happen to the movement of atoms as an ice cube melts?
they spred out
What is wrong in this sentence rock melts at calderas and then is forced towards the crust as magma?
The sentence incorrectly implies that rock itself melts to form magma. In reality, the heat from the mantle causes the surrounding rock to melt and form magma which then rises towards the crust. Consider revising the sentence to accurately reflect this process.
What happen to the subducted material in a mantle?
The part of the plate that is subducting gets melted into magma and flows back into the mantle.
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
