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 thickness of Mantle?
It is 2,900 kilometers
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 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 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.
Thickness of lower mantle?
99,877 km
What is the thickness of the lower mantle?
2900 km
What is the lower layer of the mantle called?
The mesosphere
What is above the lower mantle?
The middle mantle is just above the lower mantle.
The thickness of the earths mantle?
The Earth's mantle is approximately 2,900 kilometers thick and is composed of solid rock that lies between the Earth's crust and core. It is mainly made up of silicate minerals and is responsible for convection currents that drive plate tectonics and other geological processes on the planet.
What is the lower part of the mantle callet?
The Lower Mantle
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 thickness of Mantle?
It is 2,900 kilometers
What is the lower mantle beneath?
The lower mantle is beneath the crust.
What is the average thickness of the earths upper mantle?
410km
Which of earth layers are the thickest?
The mantle is the thickest layer of the Earth, extending from the crust to the outer core. It accounts for approximately 84% of Earth's volume and is composed of solid rock that is capable of flowing over long periods of time.
What are the part of the mantle?
The upper mantle and the lower mantle.
