Question

Which condition causes rocks to exhibit ductile deformation?

high pressure and temperature
low pressure
low temperature
being near Earth’s surface

Answer 1

High pressure and temperature cause rocks to exhibit ductile deformation.

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

The bending or flow of rocks without breaking, like clay, is known as ductile deformation.

At high temperature, rocks are malleable. As a result, they stretch more when high pressure or stress is applied. Thus, more ductile structures are formed.

Therefore, we can conclude that high pressure and temperature causes rocks to exhibit ductile deformation.
