What are the 3 sections in the mantle?
The mantle is divided into the upper mantle, transition zone, and lower mantle. The upper mantle is beneath the lithosphere, the transition zone lies between the upper and lower mantle, and the lower mantle extends to the outer core.
What is the name of the lower part of mantle and the upper part of mantle?
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
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.
Why is the lower mantle more rigid and dense then the asthenosphere in the upper mantle?
The lower mantle is more rigid and dense than the asthenosphere in the upper mantle because of higher pressure and temperature conditions. The increased pressure in the lower mantle prevents rocks from flowing as easily as in the asthenosphere. This leads to higher density and rigidity in the lower mantle region.
What are the 2 layers of the mantle?
The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more rigid, while the lower mantle is hotter and flows more easily due to higher temperatures and pressures.
What are the 3 sections in the mantle?
The mantle is divided into the upper mantle, transition zone, and lower mantle. The upper mantle is beneath the lithosphere, the transition zone lies between the upper and lower mantle, and the lower mantle extends to the outer core.
What two regions of the earth does the Gutenberg discontinuity separate?
lower mantle from upper core
What is the name of the lower part of mantle and the upper part of mantle?
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
What is the difference between between the lower and upper mantle?
The upper mantle is harder than the lower mantle
Is the second layer of the earth the upper mantle or the lower mantle?
upper mantle
What is the average depth of the upper mantle?
The upper mantle extends from the base of the Earth's crust down to a depth of about 410 kilometers (approximately 255 miles). It lies above the transition zone, which separates the upper mantle from the lower mantle. The upper mantle is primarily composed of silicate minerals and is involved in tectonic processes, including plate tectonics and mantle convection.
What are the part of the mantle?
The upper mantle and the lower mantle.
Where is the lower mantle?
under the upper mantle
Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
How do upper mantle rock differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
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.
Are convection currents found in the upper or lower mantle of earth?
The upper mantle
