Which of the following is most likely to occur at shallow crustal levels?
A) ductile behavior
B) brittle deformation
C) growth of new minerals
D) recrystallization of minerals
E) metamorphism
Crustal Levels
The various layers or strata within the Earth's crust, differing in composition, density, and formation history.
Ductile Behavior
Ductile behavior describes the ability of a material to deform under stress without breaking, often associated with rocks and metals that can bend or stretch under geological forces.
Brittle Deformation
The fracturing of rock under stress, without significant plastic deformation.
- Identify rock behaviors at different crustal levels.

Final Answer :
B
Explanation :
At shallow crustal levels, rocks and minerals are more likely to undergo brittle deformation due to the lower pressures and temperatures compared to deeper levels. This results in fracturing and faulting rather than bending or flowing.
