question 2

the theory that stress upon the crust builds and builds, deforming
the crust, and then breaking when the stress is greater than the
strength of the rocks, is called:
o richter theory
o stress - strain theory
o darwin theory
o elastic rebound theory
question 3

a fault is best described as a?
o flaw
o distinct point
o none of these are correct
o surface

Explanation:

• Question 2: The elastic rebound theory explains that when stress on the Earth's crust builds up (causing deformation) and then exceeds the rock's strength (leading to breaking), an earthquake occurs. The Richter theory is about earthquake magnitude measurement. Stress - strain theory is a general material mechanics concept. Darwin theory is about evolution.
• Question 3: A fault is a fracture or discontinuity in a volume of rock. A flaw is too general. A distinct point is incorrect as a fault is a planar or near - planar structure. A surface is also not an accurate description as a fault has specific geological characteristics related to displacement.

Answer:

• Question 2: elastic rebound theory
• Question 3: None of these are correct
