Answer:
The grain size
Explanation:
The grain size can provide lot of clues for us when it comes to the formation of the rocks, the conditions in which they formed, and even what happened after their initial formation. The reason for this is that the grains vary in size and shape depending on the conditions in which the rocks formed. If the magma/lava cooled of quickly, the grains will be very small, almost unnoticeable, and that is a sign that the cooling appeared on the surface, very close to it, or in the presence of water. On the other hand, if the magma cooled slowly, the grains will be large and well defined, and that is a sign that the magma was cooling off slowly, deep into the crust, where there's higher temperature and pressure.
Answer:
Ethiopia is most densely populated in the highlands where most people live as farmers. In the 1980s, the Socialist regime made unsuccessful attempts to forcibly relocate people away from the civil war and gather the people in new villages. Ethnically, the population is very mixed and hundreds of different languages are spoken.
More and more Ethiopians are seeking refuge in the cities today than ever before. The biggest reason why more and more Ethiopians are moving to the cities is that wages are higher there than in the countryside and that there are more jobs to choose from (in the countryside it is mostly agriculture). Despite that, only 20% of the population lives in cities and other urban areas.
Answer: Snowfield or Glacier
Explanation:
The higher one goes, the colder it becomes. This affects water as well when it falls to the earth. If it falls in an area that is cold such as high elevation areas, it would end up freezing up and becoming snow.
When this happens, it would usually be stored in an area with other snow such as a snowfield or a glacier. This is why high mountains usually have snow caps. Mt. Kilimanjaro for instance in is Mid-Africa, a region which gets no snow whatsoever yet, it still has a snow cap.
The answer to this is B. It lies west of Mississippi River and East of Rocky Mountains in the U.S and Canada.
Hope this helped :)
Have a great day <span />
