What is the sinking process that complete the lower mantle convection cell?
The sinking process in the lower mantle convection cell occurs when cooler, denser material from the upper mantle descends into the lower mantle. As this material sinks, it displaces the hotter, less dense material in the lower mantle, which then rises toward the upper mantle. This movement creates a continuous cycle of convection, facilitating heat transfer within the Earth and influencing geological processes such as plate tectonics. The sinking process is driven by thermal and compositional differences within the mantle.
What is the theory that earths crust is in a slow motion?
Plate Tectonics. The crust is in large, irregular plates shuffling around by new rock extruded from the upper Mantle in ocean plate boundaries, balanced by the loss of the fringes of the ocean-floor plates to subduction.
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.
Ocean plates are pushed down into the upper mantle in what?
Subduction Zones.
Which layer of the earth does the convection necessary for plate motion occur?
upper mantle.
What occurs when an ocean plate sinks below a continental plate?
Subduction into the upper mantle and melting.

Where is the asthenosphere and what does it do?
The asthenosphere is a section of the upper mantle that enables plate tectonics.
What is upper mantle of earth called?
I think it's called a plate
What is the theory that states that earths crust and upper mantle move around on a speacial layer of the mantle?
Plate tectonics.

What does the upper mantle and lower mantle form?
The upper mantle and lower mantle together form the Earth's mantle, which is the layer of rock between the Earth's crust and core. This region plays a critical role in plate tectonics and the movement of Earth's lithosphere.
Ocean plates are pushed down into the upper mantle in what?
Subduction Zones.
Which layer of the earth does the convection necessary for plate motion occur?
upper mantle.
Where is the location of plate tectonics?
First of all, there is no location of plate techtonics! Plate techtonics is the theory that Earth's crust and part of the upper mantle are broken into sections. These sections (plates) move on a plasticlike layer of the mantle.
Which theory describes the motion of earth's crust on its mantle?
plate tectonics=D
