While still solid, the asthenosphere is able to flow. The ability of a solid to flow is called plasticity. See "What's the matter?" for an activity to demonstrate plasticity. Since the asthenosphere is more liquid than the rest of the mantle, the broken lithosphere plates are able to "float" on it.
The plastic layer of the Earth is known as the asthenosphere. It is located beneath the lithosphere and consists of partially molten rock that allows the lithospheric plates to move slowly.
The asthenosphere, a layer of the upper mantle beneath the lithosphere, exhibits plasticity due to high temperatures and pressures. This property allows the asthenosphere to flow slowly over geological timescales and is responsible for the movement of tectonic plates.
Both the mixture of cornstarch and water and the Earth's mantle exhibit a semi-fluid behavior known as plasticity, allowing for flow over time. However, the mantle is composed of solid rock material whereas the cornstarch-water mixture is composed of two distinct phases. The plasticity of the mantle influences the movement of Earth's lithospheric plates by allowing them to slide and interact with each other along plate boundaries due to the mantle's ability to deform and flow.
The plasticity of the Earth's mantle allows it to flow slowly over geological time, creating a dynamic environment for the lithosphere plates that rest on top. This flow facilitates the movement of tectonic plates through processes like convection, where hotter, less dense material rises while cooler, denser material sinks. As the mantle deforms and moves, it drives the shifting, colliding, and separating of lithospheric plates, leading to phenomena such as earthquakes and volcanic activity. Thus, the mantle's plasticity is crucial for the tectonic processes that shape the Earth's surface.
Examples of plasticity include the brain's ability to reorganize itself after injury, such as in stroke patients where other areas of the brain compensate for damage. Muscles can also exhibit plasticity, with strength training leading to muscle growth and adaptation. Plasticity is also seen in the developing brain, where connections between neurons are constantly forming and reshaping based on experiences and learning.

Plasticity means that there is enough movement in the asthenosphere to allow thelithospheric plates to move.
The mantle exhibits a degree of plasticity known as ductile deformation, which allows it to flow slowly over long periods of time. This plasticity is essential for the movement of tectonic plates and the convection currents within the Earth's mantle, which drive plate tectonics.
The property of a solid that enables it to flow is plasticity. Plasticity refers to the ability of a solid material to change shape permanently without breaking when subjected to stress. This property allows solids to deform and flow under certain conditions, usually through the movement of dislocations within the material.
The plastic layer of the Earth is known as the asthenosphere. It is located beneath the lithosphere and consists of partially molten rock that allows the lithospheric plates to move slowly.
The lithosphere is the crust Moho and upper mantle. It floats on a plasticity zone called the asthenosphere.
Plasticity means the ability to be shaped and molded.
A plastic which will soften when heated and harden when cooled.
