A fault in which the hanging wall moves down relative to the footwall is a

ikadub [295]

The faults in which the hanging wall moves down relative to the footwall is called normal fault.

Explanation:

There are several types of faults based on their characteristics. One of them is the normal fault, or normal dip-slip fault. The main characteristic of this fault is that its hanging wall moves down relative to the footwall, while the footwall tends to move up relative to the hanging wall. The force that creates this type of faults is the vertical compression as the crust of Earth is lengthening.

These faults can be found all over the world, and they are actually the most common type of faults.
The normal dip-slip faults are bounding big portion of the mountains, as well as rift valleys.
As these faults progress with their formation, with the footwall going up, and the hanging wall going down, the footwall becomes a hill or a mountain, while the hanging wall becomes a valley.
The normal dip-slip faults can be found at all types of tectonic plate boundaries.

I need help with this begin timed

1) Pollution and acid due to industry and factories in urban areas. Africa has many problems, like famine, AIDS/HIV etc, but the pollution and acid due to industry and factories in urban areas are not a major issue right now. Though, as development does occur in some areas, this could become problems in the future.

2) A decrease in the usability of soil for agriculture. As deforestation progress, it is most likely that this issue would lead to a decrease in the usability of soil for agriculture, just like it is already happening in Amazonia and others regions that have faced similar problems.

---

3) Most Egyptian people lived and still live today close to the Nile river and Nile Delta because it is close to land that can grow crops. The majority of the Egypt agricultural production is located near the water of the Nile, the longest river on the Earth, as it permits the cultivation of various forms of crops.

---

4) If population growth occurs in an area that depends on farming, a direct result could be that deforestation will occur to clear land for additional farms. This happens because, as there is a grown in population, there is a growing in the demands of products derived from farming, and so more farms are needed in order to supply the demand. Deforestation occurs to make space for new farms.

---

5) The best term that could be used to describe the process of putting more trees in this area is reforestation. Reforestation is the opposite of deforestation, and as deforestation is a process in which trees are cut from the forest, reforestation is a process that puts more trees in an area.

6) People in South Africa would be most affected by the spread of the Kalahari Desert. The Kalahari Desert, situated mainly in Botswana, is spreading into other regions, including South Africa. Desertification is a process that could affect many sectors of the economy in the region.

7) People in Sub-Saharan Africa are least likely to live in a desert. Sub-Saharan Africa is the area of the continent that is situated fully or in part under the Sahara Desert, according to the United Nation. It is an area in which poverty is extremely diffused and that is still facing many issues.

---

8) True. The majority of Sub-Saharan African cities are located along major rivers, and the coast, because they needed access to bodies of water for trade. Historically, this was the normality for many cultures, as the access to water guarantee an access to trade and sometimes food, so it should come as no surprise that major city in the area still follows this principle.

---

9) The factor is most likely to have had the greatest impact on human settlement patterns in Sub-Saharan Africa is the proximity to water sources needed for subsistence farming. This is because water is a basic need in order to farming, so the impact would be likely to be more extended in those regions.

---

10) People in the Democratic Republic of Congo would be most affected by rain-forest conditions, as it happens that the Democratic Republic of Congo is situated where there is one of the biggest rainforests still present on the planet, so this is a factor that is a big influence on the people living in the region.

---

11) The relationship between literacy rates and a nation's standard of living is that a higher literacy rate will have a positive effect on a nation's standard of living. This happens because a higher literacy rate means more people with an higher education which mean more capable of creating or bring new jobs, which led to higher nation’s standard of living.

---

12) False. The Bantu migrations are NOT most closely associated with the Colombian Exchange. The Bantu migration happened between 1000 A.D. to 1800 A.D., while the Colombian Exchange happened during the XV and XVI century, but the two migrations are not related.

Non-Alaskan grizzly bears are indicator species for mountain ecosystems. In the nineteenth century, the grizzly bear nearly went

borishaifa [10]

Explanation:

Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed

This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.

The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.

The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.

This will go to balance the ecosystem which has been tampered or disturbed by development.

What type of agricultural practices are used in syria and how does climate affect it?

Vlad [161]

Answer:

Agricultural Practices: Pumping from rivers and flood irrigation.

How the climate affects it: During summer, the climate is dry and hot. During the winter, it's cold. Therefore, the rivers could freeze, or evaporate

Explanation:

Agricultural Practices: In Syria, the main system of irrigation is pumping from rivers and flood irrigation. In these areas, several irrigated crops are cultivated, such as the strategic crops of cotton, wheat and sugar beet. The fruit trees and early vegetables are also planted as in the Syrian coast.

How the climate affects it: The climate in Syria is dry and hot in summer and cold in winter. ... The average maximum summer temperatures in inland areas vary between 33°C and 40°C, with peaks that sometimes exceed 45°C, while the average minimum winter temperatures are around 0°C.
