Answer:
In vector calculus, the curl is a vector operator that describes the infinitesimal rotation of a vector field in three-dimensional Euclidean space. At every point in the field, the curl of that point is represented by a vector. The attributes of this vector (length and direction) characterize the rotation at that point. The direction of the curl is the axis of rotation, as determined by the right-hand rule, and the magnitude of the curl is the magnitude of rotation. If the vector field represents the flow velocity of a moving fluid, then the curl is the circulation density of the fluid. A vector field whose curl is zero is called irrotational. The curl is a form of differentiation for vector fields. The corresponding form of the fundamental theorem of calculus is Stokes' theorem, which relates the surface integral of the curl of a vector field to the line integral of the vector field around the boundary curve.
The alternative terminology rotation or rotational and alternative notations rot F and ∇ × F are often used (the former especially in many European countries, the latter, using the del (or nabla) operator and the cross product, is more used in other countries) for curl F.
Unlike the gradient and divergence, curl does not generalize as simply to other dimensions; some generalizations are possible, but only in three dimensions is the geometrically defined curl of a vector field again a vector field. This is a phenomenon similar to the 3-dimensional cross product, and the connection is reflected in the notation ∇ × for the curl.

Answer:
Seafloor spreading occurs along mid-ocean ridges large mountain ranges rising from the ocean floor.
Explanation:
The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.
Answer:
The incorrect statement is the last one: Whole wheat flout is enriched woth B-vitamins and iron.
Explanation:
The white flour or also called refined is the one that is obtained from a process in which the seed and the husk of the grains are removed to grind them, but thus the cereal loses the fiber, the iron, and many B vitamins. It is white flour that has to be enriched with B-vitamins and iron due to the significant amount of nutrients it loses during its production, its refinement.
The whole wheat flour preserves all nutrients and properties because it is obtained from whole grain.
