What is a Athensphere?
The Athensphere is not a layer in the Earth. The asthenosphere is the region of the mantle that is capable of moving by convection and has been linked to the movement of the tectonic plates (the lithosphere).
What does the asthenosphere cause?
Scientists speculate that the movement of tectonic plates is created by the movement of the rigid lithosphere on the asthenosphere.
What is the relatively soft layer of rock below the lithosphere?
The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
How convection currents drive tectonic plate movement?
by eating them
What region of the earth is soft and putty like and allows for the movement of tectonic plates?
asthenosphere
What do convection currents in the asthenosphere cause?
The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.
What causes the convection currents in the asthenosphere?
The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.
The movement of tectonic plates is inferred by many scientists to be driven by?
Convection currents in the asthenosphere
Why is the asthenosphere so important to the theory of plate tectonic?
It is the movement of ductile rock in the asthenosphere caused by convection currents that creates movement of the lithospheric plates. It is the conveyor belt on which the plates move.

What part of earths interior is inferred to have convection that cause tectonic plates to move?
the asthenosphere
What is the stress caused by in the Earth's crust?
The grinding of tectonic plates. This caused by the outer core sending heat to the asthenosphere. The heat creates convection cells (aka convection currents), which move the asthenosphere. The tectonic, or lithospheric, plates are floating on the asthenosphere. When the asthenosphere moves, the tectonic plates move, and they gring together. The grinding will eventually cause a tectonic plate to fracture, which releases energy through the earth as seismic waves, and an earthquake occurs.
Which region of the earth allows for the movement of tectonic plates?
ASTHENOSPHERE
What part of Earths interior is inferred to have convection currents that cause tectonic plates to move?
the asthenosphere
Which layers of the earth are involved in tectonic plate movement?
Basically.... The Lithosphere and The Asthenosphere.
