Question

It is believed that ______________ weaken the chemical bonds that constituent mineral grains, enabling them to act in more of a ductile manner than if this factor was not involved.

Answer 1

Water

Step-by-step explanation:

Water can help break down the grains so they become more pliable.

Answer 2

When it comes to the deformation of rocks, it is believed that water weaken the chemical bonds that constituent mineral grains. Water forms a film around the mineral and weaken the bonds. This is why wet rocks tend to act in a more ductile manner. If a rock is dry, they tend to be more brittle.
