What are some of the disagreements that led to the creation of the eastern orthodox church?

The separation of the Christian church into western and Eastern was quite anticipated on the basis of these conflicts:  

-Disagreements between churches. Churches could not find agreement either in rites, in politics or in culture.  

-Disagreements in politics. The main problem of the conflict on the political ground was the antagonism between emperors of Byzantium and the Roman Paami.  

-Disagreement in culture. The main problem in the cultural sphere was the difference between languages. So, in the east the main language was Greek, and in the West-Latin. In other words, to read each other's literature, people were looking for translations, otherwise,they were fond of different books.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
