The average composition of the oceanic crust is thought to approximate that of?
The oceanic crust is thought to approximate the average composition of the upper mantle, which is mainly composed of silicate minerals such as basalt and gabbro. These minerals are rich in elements like silicon, magnesium, and iron, which are common in the Earth's mantle.
What is the thickness of Mantle?
It is 2,900 kilometers
Where is earth greatest bulk composition located?
The Earth's greatest bulk composition is located in the Earth's mantle. The mantle is comprised of many elements that include oxygen, iron, sulfur, silicon, nickel, sulfur, magnesium, calcium, and much more.
Does The composition of the moon most closely resembles the earths mantle?
Yes, the composition of the moon's mantle is similar to that of Earth's mantle in terms of silicate minerals and elements like magnesium and iron. This similarity suggests that the moon's mantle may have been formed from materials that were also present in the Earth's mantle.
Composition of mantle?
The mantle is composed primarily of silicate minerals rich in magnesium and iron, such as olivine, pyroxene, and garnet. It also contains small amounts of other elements like aluminum, calcium, and sodium. The mantle is characterized by its solid state, although it can exhibit plastic deformation over long periods of time.

What is the balance between crust and the mantle below it?
The Earth's crust and mantle are distinct layers, with the crust being the thin, outermost layer and the mantle lying below it. The crust averages about 5 to 70 kilometers in thickness, while the mantle extends to approximately 2,900 kilometers deep. The crust is primarily composed of lighter silicate rocks, whereas the mantle consists of denser silicate minerals. This difference in composition and thickness leads to a balance where the crust floats on the more fluid-like mantle, a concept known as isostasy.
Thickness of lower mantle?
99,877 km
What is the thickness of Mantle?
It is 2,900 kilometers
What is the average thickness of the earths upper mantle?
410km
Does Mars have layers?
Yes, Mars does have layers. The planet is made up of a crust, mantle, and core. However, these layers are different from those found on Earth in terms of composition and thickness.
