Answer:
The imaginary vertical lines that run from the North pole to the South pole on a map are called longitudinal lines. The equator is equidistant from the North and South poles. Then, the equator separates the northern and southern hemispheres.
Explanation:
Forced assimilation could be a major cause of internal conflict
D. Atacama desert . . . is considered the driest non-polar desert in the world
We need to assume that the orbits are circular; this is a very good approximation and do not hesitate to adopt it. We need then to consider the basic equation of circular motion that relates centripetal acceleration, angular velocity, mass, radius and force:

. We also have the basic equation of Newton, F=ma. By checking, we see that for each planet we have that a=v^2*r where v is the angular velocity. v=

where T is the orbital period, hence we have that a=

. Denote with the index 1 the Earth case and with 2 the Mars case. We have then that

. Substituting the known values in a calculator, we get the result: the centripetal acceleration of earth is 2.32 times greater than that of Mars.
The correct answer is - T (True).
The term ''unification'', in a political sense, refers to the unification, or rather merging, of two or more countries into one country. This can be performed by countries that have been divided (for example West Germany and East Germany), countries that have mutual interest to function as one country (for example Yugoslavia), or countries that have the same ethic and cultural background but haven't been functioning as one country (for example Italy).
