Answer: Urban centers in Ethiopia are ridden by a variety of socio-economic issues such as illiteracy, unemployment, and especially poverty.
Explanation: They can also lack environmental management, lack of stability in infrastructure and buildings, as well as lack of investment in the local human population.
While there has been an increase in construction, the quality of construction itself has been poor as the government has felt pressure to rapidly build in order to meet demand and immediate needs. However this can mean very costly rehabilitation of the faulty construction in the future.
In addition, in urban Ethiopia, women out number men which has contributed to the poverty level as their main source of employment is agriculture.
Furthermore, many times there is only one main road within the urban centers which contributes to a lack of infrastructure and overcrowds the area.
Finally, there is also a lack of post secondary education and medical facilities.
Answer:
5. pycnocline.
Explanation:
Pycnocline is the rapid change in density of ocean water with depth. With increase in depth, ocean water tends to be denser. The two major factors that determine density in ocean water are temperature and salinity(salt contents). The denser water become in the ocean the more likely it sinks easily . This is one major factor that drive Ocean currents, the process is called thermohaline circulation.
The increase in salinity of ocean water causes an increase in density . This is because the salt become tightly pack and filled the water to make it denser . This simply means an increase in saline content of ocean water causes an increase in the density.
Another factor that affects density is temperature. Water at the surface possesses higher temperature due to direct contact with the sun. Usually, the higher the temperature the less dense ocean water becomes . This is why surface water is less dense. As water becomes warm the molecule disperse, this account for it lower density . Colder water are usually higher in density .
Generally, an increase in ocean depth causes considerable increase in density because of it colder temperature and increased salinity contents.
Answer:
The Rocky Mountains are a push factor.
Explanation:
There are numerous factors that contribute to migration, but all of them can be put in two wide categories, push factors and pull factors. The push factors are the factors that make people leave a certain place and move to another one. The pull factors are the factors that attract people to move into a certain place.
The Rocky Mountains can be considered as a push factor. The reason for this is that these mountains when compared to many other parts of the United States, offer very few opportunities and advantages. Especially when the large economic centers are taken into consideration, being in the same country, people naturally feel that they are missing out on a lot of things in life by living in the Rocky Mountains, so they move out of them and generally tend to migrate to the big urban areas.
