For this reason, it is required by law in many countries (including the United States) that the B vitamins thiamine, riboflavin, niacin, and folic acid be added back to white flour after processing. This is sometimes called Enriched Flour on food labels.
Transform Plate Boundaries. Transform Plate Boundaries are locations where two plates slide past one another. The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.
A transform fault boundary occurs when two plates slide past each other horizontally. Most occur on the ocean floor but some, like the San Andreas fault, occur on land. The San Andreas fault is the most famous fault boundary and is a result of the Pacific plate moving against the North American plate.
