Hypothetically, the body of planet was formed by accretion of smaller planetesimals and debris during the formative period of the solar system. The inner metallic core then segregated due to gravity, whereby the heavier metals percolated inward, leaving the lighter carbons and silicons on top, forming a mantle of liquid magma. The crust then formed due to cooling of the outer layer of magma.
Well, that's a very rough summary, at least.

What is crust and upper mantle of the EARTH?
The upper mantle is in between the lower mantle and the earths crust Crust- the outer most solid shell of the earth. The Uppermost mantle and the earth's crust form the lithosphere.
What are the 3 main layers of the earth?
MantleCrustcore
What is the layer of earth beneath the crust called?
The layer of the Earth below the crust is called the mantle. The mantle is the thickest layer of the Earth with a depth of 2,890 kilometers.
What comprises the Earth's lithosphere?
pie is awsome
What is the hardest layer in the Earth?
well, the earths crust is the hardest cause its made of rock and metal formed together.
Where did the crust on the Earth come from?
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.

What layers of earth makes up the lithosphere?
Crust and the upper mantle
In which part of the earth are diamonds most often formed?
the mantle and the crust, in the lithosphere.
How was the planets mantle formed?
The earth's mantle would have formed initially in the same way as the crust, by the cooling of the earth but as for the metamorphic rock that defines the earth's mantle, that would have taken millions of years of extreme heat and pressure for it to form.
What is crust and upper mantle of the EARTH?
The upper mantle is in between the lower mantle and the earths crust Crust- the outer most solid shell of the earth. The Uppermost mantle and the earth's crust form the lithosphere.
The section of earth beneath the crust?
Mantle Is The Below Layer Of The Crust In Earth.
What is the cycle in the mantle called?
Below the Earth's is the Earth's mantle. The Earth's crust changes through plate tectonics, the constant process where subduction describes the Earth's crust moving down into the mantle and elsewhere upheaval brings material to the surface. The process is not really a simple cycle but part of the complex geological processes of an active planet.
What parts of earth's structure combine to form the lithosphere?
The layer just below Earth's crust is the mantle. It is the thickest layer, and is composed of flowing rock material. The solid upper part of the mantle joins with the crust to form the lithosphere

How is the earth's crust formed by a volcano?
Volcanoes bring liquid rock (magma) to the surface, which may have heavier elements from the lower crust and mantle.
