Which layer of earth contains iron rich silicate rock?
The layer of Earth that contains iron-rich silicate rock is the mantle. The upper mantle is composed of silicate minerals rich in iron and magnesium, such as olivine and pyroxene. This layer lies beneath the Earth's crust and extends to a depth of about 2,900 kilometers.
What are three differences between the upper and lower mantle?
Temperature: The upper mantle is cooler than the lower mantle. Composition: The upper mantle is more silicate-rich and less dense compared to the lower mantle. Physical properties: The upper mantle is more rigid and brittle, while the lower mantle is more ductile and capable of flow.
What types of rock is in the mantle?
the mantle is made up of solid hot rock.
What layer is Composed of peridotite?
The layer composed of peridotite is the mantle, which is located between the Earth's crust and core. Peridotite is the main rock type found in the upper mantle and is rich in minerals such as olivine and pyroxene.
Is much of the upper mantle made of granite?
No, the upper mantle is primarily composed of peridotite, a rock rich in the minerals olivine and pyroxene. Granite is more commonly found in the Earth's continental crust, not in the mantle.
Does a crust separate the crust and the mantle?
No, instead of another crust, the sometimes magnesium rich Mohorovičić discontinuity separates the crust from the iron rich mantle.
Which layer of earth contains iron rich silicate rock?
The layer of Earth that contains iron-rich silicate rock is the mantle. The upper mantle is composed of silicate minerals rich in iron and magnesium, such as olivine and pyroxene. This layer lies beneath the Earth's crust and extends to a depth of about 2,900 kilometers.
How are minerals extracted from the mantle?
Minerals are extracted from the mantle through processes such as volcanic eruptions, where molten rock from the mantle (magma) reaches the surface and solidifies into mineral-rich rocks. These mineral-rich rocks are then mined or quarried to extract the desired minerals. Additionally, some minerals from the mantle may be found in oceanic crust and are extracted through underwater mining operations.
What are three differences between the upper and lower mantle?
Temperature: The upper mantle is cooler than the lower mantle. Composition: The upper mantle is more silicate-rich and less dense compared to the lower mantle. Physical properties: The upper mantle is more rigid and brittle, while the lower mantle is more ductile and capable of flow.
What is the contents of the mantle?
The mantle is primarily composed of solid rock that is rich in silicate minerals. It is divided into the upper mantle and the lower mantle, with the upper mantle being more rigid and the lower mantle exhibiting more plastic behavior due to higher pressure and temperature. The mantle is responsible for convection currents that drive plate tectonics and is a critical component of Earth's structure.
What types of rock is in the mantle?
the mantle is made up of solid hot rock.
What layer is Composed of peridotite?

Is much of the upper mantle made of granite?
No, the upper mantle is primarily composed of peridotite, a rock rich in the minerals olivine and pyroxene. Granite is more commonly found in the Earth's continental crust, not in the mantle.
What is the composition and approximate thickness of the mantle?
Earths mantle is less dense and very hot. The mantle is 2885km thick.
What pressure is the mantle?
23 g/cookies 5
What element make up the upper mantle?
The upper mantle is composed mainly of silicate minerals such as olivine, pyroxene, and garnet. These minerals are rich in magnesium and iron, which are the main elements found in the upper mantle.
What is the most abundant component of mantle rocks?
The most abundant component of mantle rocks is silicate minerals, such as olivine, pyroxene, and garnet. These minerals make up the majority of the Earth's upper mantle and are rich in magnesium and iron.
