Transform boundary

Sponsorship the way you would do it
In plate tectonics, a transform boundary fault (Also known as transform fault boundary, transform plate boundary, transform plate margin or conservative plate boundary) is said to occur when continental plates slide and grind against each other. The relative motion of such plates is horizontal in either sinistral or dextral direction.
