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.
Melted rock beneath Earth's surface is known as magma. Magma forms in the Earth's mantle and can rise to the surface, where it is then called lava. Magma can also cool and solidify beneath the surface, forming igneous rocks.
Solid rock in Earth's mantle can melt due to an increase in temperature that surpasses its melting point. This can be caused by factors like the heat generated from radioactive decay, the presence of water or other volatile substances, or the addition of heat from the Earth's core. The melted rock can then rise to the surface through volcanic activity.
The melted mineral material in the mantle is called magma.
No, the inner part of the Earth's crust is not hot melted rock. The inner core of the Earth is made up of solid iron and nickel, while the outer core is composed of liquid iron and nickel. The hot melted rock is found in the mantle layer beneath the crust.
Melted rock in the Earth's mantle is called magma.
Melted rock in the mantle, often referred to as magma, will rise when it becomes less dense than the surrounding solid rock. This typically occurs due to increased temperature, pressure release, or the addition of volatile components like water, which lower the melting point of the rock. Additionally, tectonic processes such as rifting or subduction can create conditions that facilitate the ascent of magma.
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
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.
Your answer would be melted rock, iron, and nickel
Hot melted rock, or magma, primarily rises from the Earth's mantle, which is the layer located beneath the Earth's crust. When tectonic plates shift, it can create conditions for the mantle's material to melt, forming magma. This molten rock can then move upward through cracks and fissures in the crust, often leading to volcanic eruptions when it reaches the surface.
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).

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