Answer: A question and answering teaching method.
Explanation:
Answer:
In a convergent plate boundary, two plates move towards one another. Due to this collision, the denser plate sinks below the less denser plate. It is marked by a subduction zone and deep-sea trench. Deep focus earthquakes originate in these regions. due to the high temperature and pressure at greater depth, partial melting takes place, as a result of which the plate melts and the magma being less dense, rises up towards the surface in the over-riding plate, forming volcanoes or chain of volcanic islands.
The San Andes Mountain also has formed in this way, by sharing a convergent plate boundary, where the denser Pacific plate (Oceanic crust) is subducting beneath the less dense South American plate (Continental plate).
<span>n January of 1917, British cryptographers deciphered a telegram from German Foreign Minister Arthur Zimmermann to the German Minister to Mexico, von Eckhardt, offering United States territory to Mexico in return for joining the German cause. This message helped draw the United States into the war and thus changed the course of history. The telegram had such an impact on American opinion that, according to David Kahn, author of The Codebreakers, "No other single cryptanalysis has had such enormous consequences." It is his opinion that "never before or since has so much turned upon the solution of a secret message." In an effort to protect their intelligence from detection and to capitalize on growing anti-German sentiment in the United States, the British waited until February 24 to present the telegram to Woodrow Wilson. The American press published news of the telegram on March 1. On April 6, 1917, the United States Congress formally declared war on Germany and its allies.</span>
At the turn of the 20th century, American cities had the following:
- Corruption
- Gangs
- Tenements
- Pollution and sanitation issues
As the cities grew so also did corruption as people sought to make it however way they could. Gangs were also formed for the same reason and terrorized many cities as they had political backing.
Tenements were a common feature as well in order to deal with the massive increase in population and this led to a lot of pollution and sanitation issues as the tenements were not well maintained.
In conclusion, American cities had a lot of negatives at the turn of the 20th century.
