The upper mantle is very close in chemical and mineralogical composition to?
The upper mantle is very close in chemical and mineralogical composition to the lower mantle, as both layers are primarily composed of silicate minerals such as olivine, pyroxenes, and garnet. These minerals make up the majority of the Earth's mantle and are responsible for its solid but flowing behavior.
What are the chemical compositions of the mantle?
The Earth's mantle primarily consists of silicate minerals rich in magnesium and iron, such as olivine, pyroxene, and garnet. Its chemical composition is dominated by compounds like magnesium silicate (Mg2SiO4) and iron silicate (Fe2SiO4), alongside other elements such as aluminum, calcium, and sodium. The mantle's overall composition reflects a gradient of increasing density and temperature with depth, impacting its physical properties and behavior.
What is the composition of the outer mantle?
peridotite
Which layer that is classified based on chemical composition is also found in the asthenosphere?
The layer classified based on chemical composition that is also found in the asthenosphere is the upper mantle. The upper mantle lies beneath the Earth's crust and is composed mainly of silicate minerals rich in magnesium and iron. This layer is partially molten, allowing for the plasticity that characterizes the asthenosphere, enabling the movement of tectonic plates.
What are the earths layers of rock classified by?
The Earth's layers of rock are classified by their composition and physical properties. The main layers are the crust (continental and oceanic), mantle, and core (outer and inner). These layers are distinguished by differences in chemical composition, density, and temperature.
The upper mantle is very close in chemical and mineralogical composition to?
The upper mantle is very close in chemical and mineralogical composition to the lower mantle, as both layers are primarily composed of silicate minerals such as olivine, pyroxenes, and garnet. These minerals make up the majority of the Earth's mantle and are responsible for its solid but flowing behavior.
What is the lower mantle made of?
It is made up of a magnesium silicate mineral called Perovskite. For more information on the chemical composition and mineralogy of the mantle, please see the related question.
What are the chemical compositions of the mantle?

Its chemical composition is dominated by compounds like magnesium silicate (Mg2SiO4) and iron silicate (Fe2SiO4), alongside other elements such as aluminum, calcium, and sodium. The mantle's overall composition reflects a gradient of increasing density and temperature with depth, impacting its physical properties and behavior.
List the layers of earth by their chemical composition and by their physical properties?
by the chemical composition is: the crust, the mantle (upper mantle and mantle), and the core. (you can put inner or outer) by the physical property is: lithosphere, asthenosphere, outer core, inner core. hope i helped
What is the earth's layers is most homogeneous?
The mantle is the Earth's layer that is most homogeneous in composition. It is mostly made up of solid rock and minerals, with relatively uniform density and chemical composition throughout.
What is the composition the mantle?
i dont now
What is the composition of the outer mantle?
peridotite
What is the is the composition of the mantle?
it is dead bodies
Earth's layers can be defined by their chemical composition From surface to center what are these layers?
The Earth's layers based on chemical composition are the crust (made of rocks rich in oxygen and silicon), the mantle (composed of silicate minerals rich in iron and magnesium), the outer core (mostly composed of liquid iron and nickel), and the inner core (mostly composed of solid iron and nickel).
Which layer that is classified based on chemical composition is also found in the asthenosphere?
The layer classified based on chemical composition that is also found in the asthenosphere is the upper mantle. The upper mantle lies beneath the Earth's crust and is composed mainly of silicate minerals rich in magnesium and iron. This layer is partially molten, allowing for the plasticity that characterizes the asthenosphere, enabling the movement of tectonic plates.
Rocks in the Earth's mantle contain a higher percentage of what than do rocks in the Earth's crust?
Rocks in the Earth's mantle contain a higher percentage of iron and magnesium compared to rocks in the Earth's crust. These minerals are denser and make up a significant portion of the mantle's composition, contributing to its higher density. This difference in mineral composition also accounts for the variations in physical and chemical properties between the mantle and crust.
What are the earths layers of rock classified by?
The Earth's layers of rock are classified by their composition and physical properties. The main layers are the crust (continental and oceanic), mantle, and core (outer and inner). These layers are distinguished by differences in chemical composition, density, and temperature.
