Folding and faulting are diastrophic process that occurs when the pressure deep within the lithosphere cause the earth's surface to buckle, bend and split apart.
Folding is a product of the collision between two tectonic plates that causes the crust to rise up in folds during or after an earthquake.
Thus, the answer is C. It happens along tectonic plate boundaries.
The correct answer is Creaming.
Creaming is the technique of softening solid fat, like shortening or butter, into a smooth mass and then blending it with other ingredients. In milk biochemistry it involves a process in which fat droplets come together in larger clusters that rise and float to the top of the milk.
