Is the lower mantle rock stronger than the asthenosphere?
Yes, the lower mantle rock is typically stronger than the asthenosphere. The lower mantle exhibits solid-like behavior due to high pressure, while the asthenosphere is partially molten and represents a weaker layer of the Earth's mantle.
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 is the difference between between the lower and upper mantle?
The upper mantle is harder than the lower mantle
What is the features of the mantle?
It is colder than the lower mantle.
What is the special features of the mantle?
It is colder than the lower mantle.
What is the feature of the upper mantle?
It is colder than the lower mantle.
What is the special feature of the mantle?
It is colder than the lower 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.
What Special feature of the upper mantle?
It is colder than the lower mantle.
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 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.
Is the upper or lower mantle dense?
No, it is hotter because it is closer to the inner core
