Answers

Answer 1

Answer:

The crust size remains constant because the older crust is melted at subduction zones.

Explanation:

The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.

The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.

Answers

Answer:

Job specialization encouraged leisure time, which allowed people to appreciate and develop art, sports, theater, and recreation. Citizens of early cities gained the ability to specialize in their jobs, or to work in certain trades rather than sharing agricultural or other work. Agricultural innovations like irrigation, crop cycling, and harvesting techniques meant that fewer people were needed to work as farmers and laborers. With specialized trades, more citizens in the city could work exclusively in cultural and social trades, developing art and entertainment. Cities became places where cultures developed. These developments pulled new people to cities because the city became the place to learn and experience things that could not be experienced in isolated rural environments.

Compere push and pull factors that drive migration, and give two examples of each.​

Answers

Answer:

Pull factors are the ones that attract migrants (as a strong economy), while push factors are the ones that drive migrants away (like war).

Explanation:

There are numerous different factors that make people migrate from one place to another, but all of them can be put into two broad groups, pull and push factors. The pull factors are factors that attract people to migrate in as these are the factors that offer a better life. The push factors, on the other side, are the factors that make people move away as these are the factors that make life harder.

An example of a pull factor is a strong economy. A strong economy means that the society is well developed and that job opportunities will be abundant, thus there is a chance of improving the economic status and having a better life. An example of a push factor is war. A situation where there is a war means that people feel unsafe and that they may end up losing their lives, or someone from their family and circle of friends. In order to avoid such a scenario, people move away, primarily looking for countries that offer safety.
