  4. Permeability
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The strength of a rock is its ability to resist deformation or failure under applied stress.

Multiple choice

Which type of rock failure occurs when a rock breaks suddenly and completely, without significant deformation?

  1. Brittle Failure

  2. Ductile Failure

  3. Elastic Failure

  4. Plastic Failure
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Brittle failure is characterized by a sudden and complete rupture of the rock, with minimal deformation prior to failure.

Multiple choice

What is the term used to describe the ability of a rock to absorb energy before failure?

  1. Toughness

  2. Resilience

  3. Hardness

  4. Strength
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Toughness is the amount of energy a rock can absorb before failure, representing its resistance to fracture.

Multiple choice

  1. Elasticity

  2. Plasticity

  3. Brittleness

  4. Ductility
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
