Melted rock in the mantle will rise when it becomes less dense than the surrounding solid rock and forms buoyant plumes. This can be triggered by heat sources such as mantle plumes or subduction zones.

When rock in earth's mantle melt what does it become?

Melted rock in the Earth's mantle is called magma.


How do upper mantle rock differ from lower mantle rock?

the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic


In Earth hot melted rock rises from near what?

From near the Earth's core. The mantle, located beneath the Earth's crust, is where hot melted rock, known as magma, originates. This magma can rise towards the surface through volcanic activity.


What is the material of mantle?

Your answer would be melted rock, iron, and nickel


What is the mantle and crust made up of?

Nearly all of the mantle and crust are made up of rock, and in the case of the mantle, a small percentage of magma (melted rock).


What is the Material of upper mantle?

Does lithosphere or asthenosphere contain partly melted rock from the upper part of the mantle?

The asthenosphere contains partly melted rock from the upper part of the mantle, while the lithosphere is a rigid layer of the Earth's crust and upper mantle that does not contain melted rock. The asthenosphere's semi-fluid behavior allows tectonic plates to move across it.


Is solid rock located deep in the mantle called magma?

No, solid rock located deep in the mantle is not called magma. Magma is molten rock that is found beneath the Earth's surface in the mantle and crust. Solid rock in the mantle is known as the lithosphere.

What is the part of the earth where the melted rocks are located beneath the crust?

The mantle. Specifically, the upper mantle, or asthenosphere, is directly below the crust. It is a layer of melted, but still firm and slightly gooey, rock.


How are pressure and heat involved in melting rock in the mantle?

Pressure and heat in the mantle cause the rocks to become ductile and start deforming. As pressure decreases and heat increases due to the rising of magma, the rocks reach their melting point, allowing them to melt. This melted rock can then rise to the surface as magma and form igneous rocks.
