Which best describes the costs of world war i a. millions of soldiers died, but civilians were generally spared b. millions if people died, but the economies of warring nations remained healthy c. millions of soldiers and civilians died, and the economies of europe were ruined d. economies were ruined, but few civilians died

According to official data, more people were killed and killed during the First World War, in percentage terms, than in the case of World War II. According to estimates, tens of millions of people were killed as soldiers or as civilians, while many remained wounded or with permanent psychological consequences. Also economies of many countries have been largely destroyed, hundreds of billions of dollars have been spent directly in the war, and almost so indirectly. It was a war that cost more than any other war by then.

The answer is: C.

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)

where is the rest of the question. this isn't making sense. can you upload a picture of the question?
