What else can I help you with?
Are convection currents found in the upper or lower mantle of earth?
The upper mantle
Is there two layers of mantle?
Yes, the Earth's mantle is typically divided into two 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 deeper and exhibits more plastic-like behavior.
What part of the mantle is made of soft rock that bends like plastic.?
A portion of the upper mantle known as the asthenosphere.
What is the plastic zone below the upper mantle?
The plastic zone below the upper mantle is called the asthenosphere. It is a semi-fluid layer of the upper mantle where rock can flow like a viscous fluid over long periods of time. The asthenosphere plays a crucial role in the movement of tectonic plates.
What are the special features of the upper mantle?
The upper mantle, located beneath the Earth's crust, is characterized by its solid but plastic-like behavior, allowing it to flow slowly over geological timescales. It is primarily composed of silicate minerals rich in magnesium and iron, such as olivine and pyroxene. The upper mantle also plays a crucial role in tectonic processes, including the movement of tectonic plates and the generation of magma. Additionally, the upper mantle exhibits varying temperatures and pressures, contributing to phenomena like mantle convection and the formation of hotspots.
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
How do upper mantle rocks differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
Is the second layer of the earth the upper mantle or the lower mantle?
upper mantle
What are the two parts of the mantle top and bottom?
The two main parts of the mantle are 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 closer to the core and is more fluid-like.
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".
How do you make a sentence with upper mantle?
The crust and upper mantle make up the earth.
What are the part of the mantle?
The upper mantle and the lower mantle.
What is the difference between between the lower and upper mantle?
The upper mantle is harder than the lower mantle
Is the upper mantle part of the lithosphere or asthenosphere?
The The crust and the uppermost layer of the mantle form the lithosphere. The asthenosphere, which is still in the upper mantle, is the next layer down.
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 two layers is the mantle divided into?
The mantle is divided into the upper mantle and the lower mantle. The upper mantle lies directly beneath the Earth's crust and extends to a depth of about 410 miles. The lower mantle extends from the bottom of the upper mantle to a depth of about 1,800 miles.
What is the upper mantle made of?
The upper mantle is made of something called peridodite.
