Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the fundamental physics?Distinguishes between temporary elastic deformation and permanent plastic deformation
2. What is the mathematical framework?Analyzed using stress and strain within continuum mechanics
3. Why do some materials bend back while others stay bent?Materials that are elastic bend back when the force stops, following Hooke's Law. Materials that are plastic stay bent because the force was stronger than their yield strength.
4. How do scientists use deformation to predict earthquakes?Scientists look at how the Earth's crust changes shape with tools like GPS and radar. By studying these changes, they can learn about plate movements and possible earthquakes.

Stress: Internal forces per unit area within a material resisting applied external forces.
Strain: The measure of deformation representing the relative displacement of material points.
Yield Strength: The stress at which a material begins to deform plastically.
Continuum Mechanics: A branch of mechanics that models matter as a continuous distribution of mass.
