An expansive pyramid age-structure diagram best displays the age ranges in a country that is in stage 2 of the demographic transition.
Option d
<u>Explanation:</u>
The shift in demographics from high death rates and high birth rates in societies with lower education, technologies and economically under developed to demographics of low death or birth rates in societies with advanced technology, higher education and persistent economic development and includes the stages between both the scenarios stated is named as demographic transition.
This is to suggest or evaluate the growth rate cycles of the population of the country. There are 3 types of population pyramids namely,
Expansive population pyramids - shows the population that has the greater percentage in younger age groups. Most of the 3rd world nations fall in this category.
Constrictive population pyramids - shows declining birth rates
Stationary population pyramids - depicts equal proportion of population in all age categories.
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 important information on being in each map is the right location and the impormmation of each country......
Explanation:
because its easy to find the main impormation of each country and also you will know what is the angle of the location in there and also you will see at the map where the country belong.......
