Geological Concepts Quiz

What is stress in geological terms?

• The force per unit area acting on a solid

• The temperature change in a rock

• The chemical reaction in a rock

What is strain in geological terms?

• The change in color of a rock

• The change in temperature of a rock

• The change in shape or volume of a body of rock as a result of stress
