Is the upper or lower mantle dense?
No, it is hotter because it is closer to the inner core
What portion of the mantle is more plastic?
lower
What is the difference between lithosphere and asthenosphere?
The difference between the lithosphere and the asthenosphere is that the asthenosphere is the lower part of the upper mantle it behaves like a plastic but flows much more easily than the rest of the mantle. The lithosphere however, includes the entire crust and the uppermost part of the mantle, it is more rigid and brittle and doesn't flow.
Is the lower mantle rock stronger than the asthenosphere?
Yes, it is more viscous.
Mantle layer with more convection Mantle layer with less convection?
It's mantle with less, then mantle with more as you go deeper into earth.
What is lower part of the mantle and flow even more slowly than rock in the atmosphere?
No answer
Why is the lower mantle more rigid and dense then the asthenosphere in the upper mantle?
The lower mantle is older and cooler than the upper mantle. Thank you for reading this I'm comment if you like one direction(: hehe
Is the lower mantle solid or liquid?
The lower part of the Mantle is liquid.
Is the upper or lower mantle dense?
No, it is hotter because it is closer to the inner core
Which portion of the mantle is more plastic?
lower
What portion of the mantle is more plastic?
lower
What is the Difference between the upper and lower mantle?
Working outwards from the centre: The Earth is believed to be formed of an inner core, outer core, inner mantle, outer mantle, and the crust. The mantle is two thousand miles thick and makes up more than three-quarters of the Earth's volume.
Which is more viscous the asthenosphere or the mantle?
The asthenosphere is part of the mantle, so the question is misguided. It is less dense than the lower mantle.
What is the difference between lithosphere and asthenosphere?
The difference between the lithosphere and the asthenosphere is that the asthenosphere is the lower part of the upper mantle it behaves like a plastic but flows much more easily than the rest of the mantle. The lithosphere however, includes the entire crust and the uppermost part of the mantle, it is more rigid and brittle and doesn't flow.
Is the lower mantle of the earth more solid than the upper mantle?
I think the lower mantle of the earth is mostly solid because even though the heat is extremely high, the pressureis high enough to make it a solid.
Is the lower mantle rock stronger than the asthenosphere?
Yes, it is more viscous.
How can mantle flow because its made of hot liquid magma?
Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.
