How do physical properties of the asthenosphere support the ideas of continental drift and sea floor?
The asthenosphere allows tectonic plates to move
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.
How does the plasticity of the Asthenosphere help tectonic plates move?
Because the Asthenosphere is malleable, divergent boundaries and convergent boundaries are formed. The plasticity of the Asthenosphere allows the plates to move through sea floor spreading and subduction zones.

How do the physical properties of the asthehenasphere sopport the ideas of the continental drift?
The asthenosphere allows tectonic plates to move
Which region of the earth is soft and putty-like and allows for the movement of tectonic plates?
The asthenosphere is the region of the Earth that is soft and putty-like, located beneath the lithosphere. The asthenosphere allows for the movement of tectonic plates due to its semi-fluid state, which allows the plates to slide and move over it.
What happens in asthenosphere?
It's where the plates of the lithosphere move around on, the plastic like layer of the asthenosphere. the plates move around on these
What is the role of the asthenosphere in the movement of the plates?
The asthenoshere acts like jello and allows the lithosphere, containing the plate, to move. Tectonic plates could not move without the asthenoshere.
How does Earth's asthenosphere contribute to movement of the plates?
The asthenosphere is a partially molten layer in Earth's mantle that allows the lithospheric plates to move on top of it. The heat and pressure in the asthenosphere weakens the rocks, making them more flexible and able to flow slowly. This flow in the asthenosphere causes the plates to move and interact with each other, leading to phenomena like earthquakes and volcanic activity.
What is the Role of asthenosphere in the movement of tectonic plates?
The asthenoshere acts like jello and allows the lithosphere, containing the plate, to move. Tectonic plates could not move without the asthenoshere.
What does the plates of lithosphere float on top of?
The plates of lithosphere float on top of the semi-fluid asthenosphere, which is located beneath the lithosphere in the Earth's upper mantle. The asthenosphere allows the plates to move and interact with each other due to its partially molten and more ductile nature compared to the lithosphere above it.
When plates move which type will float higher on the asthenosphere and why?
When tectonic plates move, continental plates tend to float higher on the asthenosphere compared to oceanic plates. This is because continental plates are generally thicker and less dense, composed mainly of lighter granitic rocks, whereas oceanic plates are thinner and denser, primarily made of basalt. The lower density of continental plates allows them to "float" more buoyantly on the semi-fluid asthenosphere beneath.
