The asthenosphere lies beneath the lithosphere, which is where the tectonic plates lie. Because of the high temperature, the asthenosphere has the property to flow (plasticity); the tectonic plates "float" on this flow.
What else can I help you with?
What process within earth's asthenosphere is responsible for plate motions?
The process responsible for plate motions within the Earth's asthenosphere is mantle convection. This is where heat from the Earth's core drives the movement of the asthenosphere, causing the tectonic plates to move across the surface of the Earth.
Do tectonic plates move around on the asthenosphere?
Yes
What is the soft layer of the mantle on which the tectonic plates move?
The soft layer of the mantle on which the tectonic plates move is called the asthenosphere. It is a semi-fluid layer beneath the lithosphere that allows for the movement of the tectonic plates due to convection currents in the mantle.
What is the soft layer of the mantle where tectonic plates move?
asthenosphere
What are Large pieces of lithosphere that move around on the asthenosphere?
tectonic plate
What is the solid plastic layer of earth on which tectonic plates move?
The asthenosphere.
Structures in earth that move on the asthenosphere?
Tectonic plates are the structures that move on the asthenosphere. These plates float on the semi-fluid asthenosphere, driven by the heat from Earth's interior, causing them to slowly move and interact with each other, leading to processes like earthquakes and volcanic activity. The movement of tectonic plates is responsible for shaping the Earth's surface through processes like subduction, seafloor spreading, and mountain building.
What structures in the Earth move on the asthenosphere?
Tectonic plates are the structures in the Earth that move on the asthenosphere. These plates float on the semi-fluid asthenosphere and interact with each other, leading to processes like plate tectonics, earthquakes, and volcanic activity.
What do the tectonic plates float on?
The tectonic plates, part of the lithosphere, move around and float on the top of 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.
How do physical properties of the asthenosphere support the ideas of continental drift and sea floor?
The asthenosphere allows tectonic plates to move
What part of earths interior is inferred to have convection that cause tectonic plates to move?
the asthenosphere
