How is the lower mantle different from the inner core?
The lower mantle is a solid layer located between the upper mantle and the outer core of the Earth, composed mainly of silicate minerals. In contrast, the inner core is a solid sphere composed primarily of iron and nickel at Earth's center due to extreme pressure. The lower mantle is part of the mantle layer, whereas the inner core is part of the core layer of the Earth.
Which of the Earths layers is just below lower mantle?
The layer just below the lower mantle is the outer core. This layer is composed of liquid iron and nickel, and is responsible for generating Earth's magnetic field.
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 layer of the earth that lies above the outer core?
The layer of the Earth that lies above the outer core is the mantle. It is a viscous layer composed of silicate rocks and is divided into the upper mantle and the lower mantle. The mantle is responsible for most of the Earth's internal heat and convection currents that drive plate tectonics.
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.
What is the earth's lower mantle?
The lower mantle of the Earth is the layer directly above the core. It is very dense, hot, and composed of thick rock.
How is the lower mantle different from the inner core?
The lower mantle is a solid layer located between the upper mantle and the outer core of the Earth, composed mainly of silicate minerals. In contrast, the inner core is a solid sphere composed primarily of iron and nickel at Earth's center due to extreme pressure. The lower mantle is part of the mantle layer, whereas the inner core is part of the core layer of the Earth.
Earths middle layer?
The middle layer of the Earth is called the mantle. It is a region of solid rock that extends from the base of the crust to the outer core. The mantle is composed of silicate minerals and is divided into the upper mantle and the lower mantle.
What part of the mantle is the asthenosphere found?
The asthenosphere lies in, and is the upper ductile part of, the mantle. It is the layer directly underneath the lithosphere; the layer composed of the crust and uppermost rigid mantle.
What the lower layer of the mantle is composed this material?
The lower layer of the mantle, known as the mesosphere, is primarily composed of solid silicate minerals rich in magnesium and iron, such as olivine and pyroxene. This region experiences high pressure and temperature, which keeps the materials solid despite their proximity to the molten outer core. The lower mantle plays a crucial role in Earth's geology, affecting mantle convection and plate tectonics.
What word best characterizes the lower mantle?
The word that best characterizes the lower mantle is "solid." The lower mantle is composed of solid rock materials that can flow very slowly over long periods of time. This layer is located between the upper mantle and the outer core of the Earth.
What is the lower layer of the mantle called?
The mesosphere
Which of the Earths layers is just below lower mantle?
The layer just below the lower mantle is the outer core. This layer is composed of liquid iron and nickel, and is responsible for generating Earth's magnetic field.
Which layer of the is composed of liqiud iron and nickel?
mantle
List the layers of earth by their chemical composition and by their physical properties?

Is the second layer of the earth the upper mantle or the lower mantle?
upper mantle
What is the layer that makes up most of the earth's mass and vloume is the is what?
The layer that makes up most of the Earth's mass and volume is the mantle. It is located between the Earth's crust and core and is composed of solid rock that is capable of flowing over long periods of time. The mantle is divided into the upper mantle and the lower mantle, with the upper mantle being partially molten and the lower mantle being solid.
