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 Difference between the upper and lower mantle?
The main difference between the upper and lower mantle is their depth within the Earth. The upper mantle is located closer to the Earth's surface, extending from the crust to a depth of about 410-660 km, while the lower mantle lies beneath the upper mantle, extending from around 660-2,891 km deep. Additionally, the upper mantle is more rigid and composed of mainly solid rock, while the lower mantle experiences higher pressures and temperatures, leading to more plastic behavior.
What are the 3 sub layers of the mantle?
The three sub layers of the mantle are the lithosphere, asthenosphere, and mesosphere. The lithosphere is the rigid outer layer consisting of the crust and upper part of the mantle. The asthenosphere is a partially molten layer beneath the lithosphere that allows for the movement of tectonic plates. The mesosphere is the lowermost and solid part of the mantle.
What are the principal divisions of the solid earth based on compositional differences?
The principal divisions of the solid Earth based on compositional differences are the crust, mantle, and core. The crust is the outermost layer and is composed mainly of lighter elements like silicon and oxygen. The mantle lies beneath the crust and consists of denser silicate minerals. The Earth's core is located at the center and is primarily made up of iron and nickel.
What are tge 3 layers of tye geosphere?
The three layers of the geosphere are the crust, mantle, and core. The crust is the outermost layer and is divided into continental and oceanic crust. The mantle lies beneath the crust and is divided into the upper and lower mantle. The core is the innermost layer and is further divided into the outer core and inner core.

What are the three spheres in the mantle called?
The three main spheres in the Earth's mantle are the upper mantle, the transition zone, and the lower mantle. The upper mantle extends from the Moho (the boundary between the crust and the mantle) to about 410 kilometers deep, while the transition zone lies between 410 and 660 kilometers. The lower mantle extends from 660 kilometers to the outer core, reaching depths of around 2,900 kilometers. Each of these layers has distinct physical and chemical properties that influence geological processes.

What is middle layer of earth called?
Between the thin rocky crust and inner core, in order from upper to lower, are the upper mantle, mantle, and outer core.
Is earth divided by composition into three layers?
The 3 main layers of earth (crust, mantle, core) are divided into crust, upper mantle, lower mantle, outer core, and inner core.
What are three major subdivision of the earth?
The three major subdivisions of the Earth are the crust (including the continents and ocean floor), the mantle (made up of the upper mantle and lower mantle), and the core (which consists of the outer core and inner core). These subdivisions are based on differences in composition, density, and physical properties.
What are the three interior layers of the earth from answers com?
Technically, the most interior is the inner core, then the outer core, then the lower mantle
What three parts that make up Earth's mantle?
The three parts that make up the Earths mantle are the crust, core, and mantle.
