During Subduction does the mantle melt?
Yes, during subduction, the mantle can melt. As an oceanic plate descends into the mantle, it carries water and other volatiles, which lower the melting point of the surrounding mantle rocks. This process can lead to the formation of magma, contributing to volcanic activity at subduction zones. The resulting magma can rise to the surface, forming volcanic arcs.
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
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.
When rock in earth's mantle melt what does it become?
Melted rock in the Earth's mantle is called magma.
When rocks are pushed down into the mantle and melt it become?
When rocks are pushed down into the mantle and melt, they become magma. Magma is molten rock located beneath the Earth's surface.

How do convergent boundaries add material to earths surface?
At convergent boundaries some mantle material can melt and rise through the crust, forming volcanoes.

What produces the heat necessary to melt rocks in the mantle?
Pressure
What might cause solid rock in the Earth's interior to melt and begin to flow?
The mantle cause the mantle to flow.
Why is the upper mantle solid?
the entire mantle is solid because the pressure is so great the rock are unable to melt.
What is a layer of slowly forming rock in the mantle?
Asthenosphere
Why do rocks melt in the upper mantle?
Rocks melt in the upper mantle due to high temperatures and pressure from the Earth's interior. The increase in temperature lowers the rocks' melting point, allowing them to transform into magma. This process is known as partial melting.
What role do pressure and temperature play in magma formation?
As rising superheated mantle rock nears the surface due to tectonic forces, the compression pressure from surrounding rock decreases, causes it to melt, forming magma. It's called decompression melting. The high pressures that keep the superhot mantle rock from melting in the first place are called lithostatic pressures.
