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.

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.
What is the approximate thickness of the ice at location A?

Almost 2900 km thick.
Why does radiation not occur in Earth's mantle?
The Earth's mantle is composed of solid rock that is not undergoing radioactive decay, which is the process that releases radiation. The radiation that is naturally emitted from the Earth mainly comes from the crust and the core, not the mantle. Additionally, the thickness and composition of the mantle act as a barrier that prevents most radiation from reaching the surface.
