A topographic map is a sort of map categorized by large-scale detail and measurable illustration of relief, normally using contour lines that has an elevation of highest and lowest. The difference between highest and lowest contour lines is RELIEF, The high relief, and low relief. The example of high relief are mountains; they are mapped with large contour intervals. While plains are the example of low relief that normally mapped with small contour intervals.
The correct answer is - Americans moved west in the 1800's because people wanted to get a fresh start and wanted to be able to buy their own land, as well as to try new economic possibilities, such as farming and gold mining.
In the 1800's the situation in the west started to stabilize and be much more attractive for people to move in. The problems with the native American populations were almost totally put under control so the safety issue was mostly resolved. Also the government had policies to give free land or for very small amount of money as to attract people to move there and thus have the demographic basis for implementing their rule more efficiently. For lots of people, mostly the ones from the lower class, this was seen as a golden opportunity and they used it as quick as possible.
We have that the first assertion is true. Political instability leads to a fight for power that is fierce and the government does not care about its people or it does not have the time to make changes in the economy. The second statement is also correct, since militias are one of the organized parts of Somali society at this point. The third point is also correct and is not happening only in Somalia. Hence, D is the correct choice.
A subduction zone is also generated when twooceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.
