Answer:
Convection in the Mantle (heat driven)
Ridge push (gravitational force at the spreading ridges)
Slab pull (gravitational force in seduction zones)
Explanation:
Image result for Tectonic plates move due to what forces
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.

I am pretty sure the answer is B:some severe thunderstorms.
Answer:
More choices.
Explanation:
Cities are very densely populated because there are a lot of opportunities for a job. There are also plenty of places to send children to school. In bigger cities there are also more schools so if you were going to school you could have a choice on which school you wanted to go to. There would also be responses to bad weather such as a lot of snow the plows would be out or if there was an issue at home there are homes and shelters.
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.
