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.
What else can I help you with?
What Special feature of the upper mantle?
It is colder than the lower mantle.
Are convection currents found in the upper or lower mantle of earth?
The upper mantle
Which of the Earth's layers is located just below the mantle?
The layer located just below the mantle is the outer core. It is composed of a liquid layer of iron and nickel that surrounds the solid inner core of the Earth.
What can flow if the upper mantle?
Magma can flow if the upper mantle, leading to volcanic activity on the Earth's surface.
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 Special feature of the upper mantle?
It is colder than the lower mantle.
What is the special features of the mantle?
It is colder than the lower mantle.
Is the second layer of the earth the upper mantle or the lower mantle?
upper 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 special feature of the upper mantle?
One special feature of the upper mantle is that it is mostly composed of solid rock but can exhibit some partial melting in certain regions, leading to magma formation. It plays a key role in tectonic plate movements and is involved in processes like convection that drive mantle dynamics.
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.
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.
What is the difference between between the lower and upper mantle?
The upper mantle is harder than the lower mantle
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.
What are the that make up the upper mantle?
What are the layers that make up the upper mantle.
