The zone of plasticity refers to a region within a material where deformation occurs permanently under stress, without returning to its original shape when the stress is removed. This concept is often used in materials engineering to understand the behavior of materials under loading conditions.
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.
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.
Morphological plasticity is the tendency of a species to physically change appearance due selective breeding. Some species, like dogs, have a high degree of morphological plasticity - a few generations can turn a wolf into a chihuahua - whereas others, such as humans, have such a low degree that thousands of years of separation yields only minor changes to facial structure and hair type. The mechanisms which govern this effect are complex and numerous, but there seems to be a correlation between high plasticity and the species' natural rate of environmental adaptability.
The conclusion of the plastic and liquid limit test is to determine the plasticity characteristics of soil, specifically its plastic limit (PL) and liquid limit (LL). These limits help classify the soil's behavior under varying moisture conditions, indicating its workability and potential for deformation. The plasticity index (PI), calculated as the difference between LL and PL, provides insight into the soil's plasticity, with higher values indicating greater plasticity and potential for engineering challenges in construction and design.
Think of plasticity as the opposite of elasticity. Elastic materials will deform under an applied force, but will return to their original shape when the force is removed. It is also the opposite of "easy to crack." We are not speaking of gasses or liquids. Plasticity is a property of many solids which tend to keep their new shape once deformed by an applied force. Soft metals like copper and lead are highly 'plastic.' They are easy to hammer into a new shape or draw out into a wire. Rock candy, peanut brittle, and high-carbon steel tools made for cutting have a very low plasticity. They are brittle. Rubber bands also have a low plasticity, as they return to their original shape when let go. Ironically, many types of plastic (vernacular usage) are easy to shatter under stress, and so have very little plasticity, by definition.
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.

Brain plasticity refers to the brain's ability to reorganize itself by forming new connections between neurons. Factors that influence plasticity include age (plasticity decreases with age), environmental enrichment (such as learning new skills or engaging in stimulating activities), physical exercise, nutrition, and certain experiences or stimuli. Additionally, genetic variations can also play a role in determining an individual's level of brain plasticity.
No they do not.

A damaged brain shows some measure of plasticity, and it has the ability to rewire itself.
