Has grown less common over time, due to multiple social and economic conditions, including increasing levels of democracy, a declining acceptance of arranged marriage, an increase in marriages based on a desire for love and companionship, and strides in the education and human rights protections afforded to women.

"Polygamy" has grown less common over time, due to multiple social and economic conditions, including increasing levels of democracy, a declining acceptance of arranged marriage, an increase in marriages based on a desire for love and companionship, and strides in the education and human rights protections afforded to women.

Explanation:

Polygamy is the act of having more than one husband or wife at the same time, in every combination. It is a type of relationship that as lost presentation among the population, but in the past was very popular and in many religions supported. Most often it was a misogynist movement in societies, systems, and cultures supporting sexism. Right now it is not seen very often because equality has brought light to many of us. It also was a practice that permitted abuse over women.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)

manifest functions are the recognized and intended consequences of any social pattern, while latent functions are those unrecognized and unintended consequences. to analyze the manifest functions of any social institution, we have to study its contribution to the continuation of a group, community, or society.
