It is mostly solid rock, but less viscous at tectonic plate boundaries and mantle plumes. Mantle rocks there are soft and able to move plastically (over the course of millions of years) at great depth and pressure. The transfer of heat and material in the mantle helps determine the landscape of Earth
What else can I help you with?
What is the uppermost part of the mantle that has liquid and plastic properties called?
The uppermost part of the mantle with liquid and plastic properties is called the asthenosphere. It is a semi-fluid layer located beneath the rigid lithosphere that allows for the movement of tectonic plates.
What part of the earth is very hot and has properties of both solids and liquids?
The Mantle Is The Part Of Earth That Has Properties Of A Solid And A Liquid.
What is the stiffer mantle made from?
The stiffer mantle, often referred to as the upper mantle, is primarily composed of silicate minerals rich in magnesium and iron, such as olivine, pyroxene, and garnet. These minerals are denser and more viscous compared to those found in the lower mantle, contributing to the upper mantle's rigidity. The high pressure and temperature conditions at these depths also influence the physical properties, making the mantle stiffer and more resistant to flow.
What is compression in the earth's mantle?
Compression in the Earth's mantle refers to the process by which rocks are pushed together, resulting in increased pressure and density. This compression can lead to changes in the physical and chemical properties of the rocks, affecting their behavior and deformation within the mantle.
What are the three spheres in the mantle called?
The three main spheres in the Earth's mantle are the upper mantle, the transition zone, and the lower mantle. The upper mantle extends from the Moho (the boundary between the crust and the mantle) to about 410 kilometers deep, while the transition zone lies between 410 and 660 kilometers. The lower mantle extends from 660 kilometers to the outer core, reaching depths of around 2,900 kilometers. Each of these layers has distinct physical and chemical properties that influence geological processes.
Why there are different properties in the mantle and core?
Their different properties are due to their chemistry, pressure, and temperature.
Is the mantle divided into layers based on the physical properties?
no, it cant be the properties because the earth's mantle was thought to be different then what we think it is now. i am pretty sure it is where the sections are located at.
Is the mantle of earth studied directly or indirectly?
the mantle is molten lava and assorted other properties; of course we can't study it directly
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.
What happen to the rocks in the mantle?
the minerals posses a number of properties that are used as an aid in their identitification

What does the contour intercal represent?
The contour intercal is a layer within the Earth's mantle that separates the upper and lower mantle. It is marked by a change in density and seismic wave velocities, indicating a boundary between different compositional and rheological properties of the mantle. It plays a role in the dynamics of mantle convection and the movement of tectonic plates.
Which word best characterize the lower mantle?
The word 'cool' best characterizes the lower mantle.
What is the area between the mantle and core where hot rocks forced into the crust?
The area is known as the mantle transition zone and it is located between the upper mantle and the lower mantle. This region is characterized by high pressures and temperatures, causing rocks to undergo changes in their physical and chemical properties.
