Answer:
The composition of Earth's core Solid iron surrounded by molten iron .
Explanation:
Earth's Core -
Earth's core is the hottest and the deepest layer in the Earth . It is composed of two layers , first is , the outer core , which is type of border between the mantle and the core , and second is the inner core .
The inner core is rich in solid , and mainly contains iron , and the outer core is in liquid state , which is rich in nickel and iron metals . the outer core is where the Earth gets its magnetic field .
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:
The Colorado stream is extremely helpless by human abuse, natural issues, and destitute stream administration procedure. As a especially over-apportioned water asset, the water quality of the stream is jeopardized by agrarian overdraw, that will increment the saltiness of the stream. to boot, this overdraw is overstated by climactic changeability. With overstated temperature and variable precipitation, the amount of snowmelt contributive to the stream of the stream will exclusively diminish, that subsequently diminishes its capacity capability.

Answer:
Pioneers moved west through a desire to make their fortune through the farming of previously unfarmed lands – too many people it was regarded as an extremely exciting opportunity, a chance of a new life. -The attraction of cattle farming encouraged people to move out west.
